Pricing & Quotes (10)

How much do fuel delivery companies charge?
Most Florida fuel delivery companies charge a per-gallon rate that combines the wholesale fuel cost (OPIS rack price) plus a delivery margin of roughly $0.20 to $0.60 per gallon, with the spread driven by volume, distance, and fuel type. On orders below 200 gallons many providers add a flat service fee of $35 to $150. Exigo Fuels publishes itemized invoices showing rack price, margin, and delivery fee separately so commercial buyers can audit pricing against their fuel index. Volume customers ordering 1,000+ gallons routinely pay below local cardlock pricing. Call (305) 900-6725 for a quote indexed to your delivery address and weekly volume.
How much to deliver diesel?
In South Florida, diesel delivery typically runs the OPIS Miami rack price plus $0.20 to $0.55 per gallon depending on volume and location, with no separate trip charge for orders of 200 gallons or more. Smaller drops (under 200 gallons) generally carry a $75 to $150 minimum-stop fee. Off-hour deliveries (nights, weekends, holidays) and emergency dispatch within 1 to 4 hours add a premium of $0.10 to $0.30 per gallon. Account customers on standing-order programs typically beat retail cardlock by $0.40 to $0.80 per gallon once delivery is included. Get a written quote at exigofuels.com/contact.
How much is diesel in Miami, Florida?
Miami diesel pricing tracks the OPIS Gulf Coast and Miami terminal rack assessments and changes daily. Retail diesel in Miami-Dade typically runs $0.30 to $0.70 per gallon above wholesale rack, while bulk on-site delivery for commercial accounts often lands within $0.20 to $0.40 of rack on volume orders. Florida levies a state diesel fuel tax of roughly $0.36 per gallon plus federal excise of $0.244 per gallon (clear diesel only). Off-road dyed diesel sold under IRS Section 4082 is exempt from federal road tax. For a current Miami delivered price quote tied to your weekly volume, call (305) 900-6725.
How much is diesel fuel in Miami, Florida?
Diesel fuel in Miami, Florida is priced off the daily OPIS Miami terminal rack and varies with crude markets, refinery output, and seasonal demand. Commercial buyers using on-site fuel delivery typically pay rack plus $0.20 to $0.40 per gallon all-in, while small-quantity retail buyers see rack plus $0.40 to $0.80. Clear (on-road) diesel includes Florida state fuel tax (~$0.36/gal) and federal excise ($0.244/gal); dyed off-road diesel for generators, construction, and agriculture is sold tax-exempt. Pricing differs slightly between Hialeah, Doral, and Port of Miami terminals. Request a delivered quote at /diesel-fuel-supplier/.
Is it cheaper to have fuel delivered?
For commercial fleets, yes. Once you account for driver labor (paid time spent at retail pumps), vehicle deadhead miles to and from a station, transaction fees on cardlock networks, and lost productive hours, on-site fuel delivery typically beats retail by $0.30 to $0.80 per gallon on volumes above 500 gallons per week. Single-vehicle owners or low-volume users (under 100 gallons per month) generally pay more for delivery than self-service retail because of minimum-stop fees. The breakeven point for most South Florida fleets is around 300 to 500 gallons per delivery. See our cost breakdown at /blog/how-much-does-fuel-delivery-cost-florida/.
How to find cheap diesel fuel?
The cheapest diesel for commercial buyers comes from rack-indexed bulk delivery, not retail stations. Negotiate a contract priced as OPIS Miami daily average plus a fixed margin (e.g., rack + $0.18) so you ride the wholesale market rather than retail markup. For fleets above 5,000 gallons per month, ask your supplier for index-plus quotes from at least three providers and request itemized invoices showing rack, margin, taxes, and fees as separate line items. Off-road operations (construction, generators, marine) qualify for tax-exempt dyed diesel under IRS §4082, saving roughly $0.60 per gallon in road taxes. Exigo Fuels publishes a transparent rack-plus structure — call (305) 900-6725.
How to get wholesale diesel?
To buy wholesale diesel you need either a Florida fuel tax license (for resellers) or a commercial bulk delivery account with a licensed supplier (for end users). Most fleet operators, marinas, generator owners, and construction firms qualify for the second path: open a credit account, set up a bulk on-site tank or scheduled delivery program, and pay the daily wholesale rack price plus a delivery margin. Federal Form 637 registration is required for tax-exempt dyed diesel use. Exigo Fuels onboards qualifying commercial accounts in 24 to 48 hours with net-15 or net-30 terms based on credit. Apply at /services/fuel-wholesale/.
How to get fuel and pay later?
Most commercial fuel suppliers offer net-terms billing for qualifying business accounts. Exigo Fuels extends net-15 and net-30 terms to approved commercial customers, with credit decisions usually returned within one business day after a brief application that requires a federal EIN, bank reference, and one or two trade references. Larger accounts can negotiate net-45 or net-60. Fleet operators preferring per-transaction billing can use a fuel card program for over-the-road purchases at thousands of stations with consolidated weekly invoicing. New accounts and one-off deliveries are typically prepaid by ACH, wire, or card. Apply at /contact/.
How much does a fuel supplier make?
Fuel distributor margins are thin: industry data from the National Association of Convenience Stores and the Petroleum Marketers Association of America puts gross margin at $0.10 to $0.30 per gallon on bulk commercial delivery, with net operating margin closer to $0.03 to $0.08 after fuel cost, transport, insurance, equipment, and labor. Larger distributors run higher absolute dollars on volume; specialty providers (marine, aviation, emergency) earn higher per-gallon margins because of regulatory complexity and on-call dispatch. Industry-wide, fuel wholesale and distribution operate on 1% to 3% net profit, which is why pricing transparency and volume pricing matter to commercial buyers. Compare itemized quotes before signing a supply agreement.
Do you offer fuel price lock contracts?
Yes. Exigo Fuels offers fixed-price contracts and index-plus agreements for qualifying commercial accounts to protect against market volatility. Fixed-price terms typically run 3 to 12 months on committed monthly volumes, with an upfront price agreed regardless of OPIS movement. Index-plus contracts hold a guaranteed margin (e.g., rack + $0.18) over the daily OPIS Miami assessment, giving full transparency while keeping pricing competitive when markets soften. Larger accounts can layer hedge instruments through their broker. We help commercial buyers model breakeven, cap exposure, and pick the structure that fits their budget cycle. Contact our sales team at (305) 900-6725 to discuss available pricing structures.

Service Mechanics — How Delivery Works (10)

Can you get diesel fuel delivered?
Yes. Diesel fuel can be delivered directly to commercial sites, fleet yards, generators, marinas, construction equipment, and reefer units throughout Southeast Florida. Exigo Fuels operates DOT-compliant tanker trucks dispatched from our Hialeah hub to Miami-Dade, Broward, and Palm Beach counties. Delivery includes both clear (on-road, taxed) and dyed (off-road, tax-exempt) ULSD #2 meeting ASTM D975. Drivers handle tank-fill, equipment fueling, and meter-ticketed transactions with itemized receipts showing gallons, fuel type, and time of delivery. Same-day and 24/7 emergency service is available. Schedule a delivery at /services/on-site-fuel-delivery/.
How is diesel delivered?
Diesel is delivered by DOT-licensed tanker trucks ranging from 1,000-gallon mobile fuel trucks for equipment and small tanks up to 9,000-gallon transport trailers for bulk fills. Each truck carries a calibrated meter, certified ticket printer, and grounding cable to verify the volume dispensed and prevent static ignition. The driver verifies the receiving tank capacity and product compatibility, connects the discharge hose, pumps fuel through a filter, then prints a ticket showing gallons, product code, time, and tank ID. For dyed diesel, IRS-required red dye is added at the terminal, not at the tank. Spill kits, fire extinguishers, and HAZMAT placards are carried on every truck.
How does mobile fuel delivery work?
Mobile fuel delivery brings diesel or gasoline directly to your fleet, equipment, or storage tank using a dedicated fuel truck rather than requiring vehicles to drive to a retail station. The customer schedules a delivery (one-time or recurring), provides the address and tank or vehicle list, and the supplier dispatches a metered tanker that fuels each unit on-site. Each transaction is logged with gallons, vehicle ID, and time. Programs typically run overnight or during off-shift hours so vehicles are full and ready at the start of each workday. Exigo Fuels offers wet-hose mobile fueling for fleets, generators, and marine vessels — see fuel delivery.
How to get gasoline delivered to your house?
Residential gasoline delivery in Florida is restricted under NFPA 30A and Florida Department of Agriculture rules: licensed bulk delivery is permitted only to approved tanks (above-ground or underground) that meet code, not directly into vehicle tanks at single-family residences. Homeowners with a permitted on-property fuel tank for a generator, boat, or farm equipment can receive delivery. For a personal vehicle that ran out of fuel, several consumer apps offer roadside refueling with portable cans, but those are not bulk fuel delivery — they are emergency roadside services. Exigo Fuels delivers to permitted residential generator and marine tanks throughout Southeast Florida.
Is there an app that delivers gas?
Several consumer apps (Booster, Yoshi, EzFill in some Florida markets) deliver small quantities of gasoline directly to personal vehicles in residential and office parking lots. These services target individual drivers and target volumes of 5 to 25 gallons per vehicle. For commercial fuel buyers — fleets, generators, marinas, construction sites — app-based consumer delivery is not a fit; commercial volume requires a licensed bulk supplier with metered tankers, DOT compliance, and itemized B2B billing. Exigo Fuels is a commercial bulk supplier serving Southeast Florida 24/7. To schedule, call (305) 900-6725 or use the contact form at /contact/.
What app can bring me gas?
Consumer-side apps such as Booster, Yoshi, and EzFill offer on-demand gasoline to personal vehicles in select U.S. markets, with availability that varies by ZIP code. Coverage in South Florida is uneven and these services typically cap at 25 gallons per visit. They are not designed for commercial fleet, generator, or marine fueling. For business needs in Miami-Dade, Broward, or Palm Beach, schedule a commercial delivery with a licensed bulk supplier — Exigo Fuels handles diesel, gasoline, and marine fuel from 100 gallons up to bulk truckload. Reach our 24/7 dispatch at (305) 900-6725 or schedule online at /contact/.
How much does a mobile fuel truck cost?
A new mobile fuel delivery truck in 2026 costs roughly $140,000 to $260,000 depending on tank size, configuration, and chassis. A 1,000- to 2,000-gallon DOT-compliant straight truck with single-product tank, calibrated meter, hose reel, and ticket printer typically lists at $140k to $180k; a multi-compartment 3,000- to 4,000-gallon truck supporting two products (diesel and gasoline) runs $180k to $260k. Larger 9,000-gallon transport trailers used for terminal-to-tank bulk runs cost $90k to $160k for the trailer alone, paired with a tractor at $130k+. Add insurance, HAZMAT permitting, driver CDL with HAZMAT endorsement, and ongoing maintenance.
How quickly can you deliver fuel?
Standard commercial fuel deliveries in Southeast Florida are completed within 24 hours of an approved order; same-day delivery is available for most Miami-Dade, Broward, and Palm Beach addresses if booked before midday. Emergency dispatch for hospitals, data centers, telecom sites, and life-safety generators is available 24/7 with on-site arrival within 1 to 4 hours from our Hialeah hub depending on tier. Recurring fleet and generator customers are placed on standing weekly or biweekly schedules so tanks never drop below threshold. Call our 24/7 dispatch at (305) 900-6725 to confirm response time for your address.
Do I need to be present during the fuel delivery?
No. For above-ground and underground tank fills, deliveries can be completed using a tank access code, key lockbox, or pre-authorized site instructions. Drivers follow strict spill-prevention and metering protocols regardless of whether a customer contact is on-site, and every transaction is documented with a printed ticket showing gallons, fuel type, time, driver, and truck ID. For wet-hose fleet fueling and on-equipment refueling, a site contact is helpful to identify vehicles but is not required when a vehicle list and yard access plan are on file. Receipts and invoices are emailed and available in your account portal.
What is your minimum delivery amount?
Minimum delivery quantities depend on fuel type and service. Marine fuel delivery to docked vessels has a 250-gallon minimum. Commercial on-site delivery to construction sites, fleet yards, and generators typically starts at 200 to 500 gallons depending on location. Bulk on-site delivery for industrial operations starts at 1,000 gallons with volume discounts on orders above 5,000 gallons. Below-minimum orders may incur a flat short-stop fee. Recurring scheduled deliveries on a standing program qualify for lower minimums and preferred pricing. For a custom quote tied to your fuel type, volume, and location, contact (305) 900-6725 or sales@exigofuels.com.

Fuel Types & Specs (8)

Where do you get diesel fuel from?
Exigo Fuels sources ULSD #2 diesel from major refinery terminals on Florida's East Coast, primarily the Port Everglades, Port of Miami, and Tampa terminal racks supplied by Marathon, Chevron, Valero, Citgo, and other Tier-1 refiners. Each load is documented with a refiner BOL (bill of lading), batch ID, and ASTM D975 conformity certificate. Loads are pulled fresh from the rack, never blended on-truck, and dyed off-road diesel is dyed at the terminal per IRS rule. This sourcing model gives commercial buyers full traceability from refinery to tank — important for fleet warranty claims, generator servicing, and EPA tier compliance.
Is HFO cheaper than diesel?
Yes. Heavy fuel oil (HFO, also called bunker fuel or residual fuel) is significantly cheaper than diesel — typically 30% to 50% lower per gallon — because it is a heavier refining cut requiring less processing. HFO is used in large marine engines, industrial boilers, and some power plants where engine design tolerates its higher viscosity, sulfur content, and contaminants. It cannot be used in modern on-road diesel engines, generators, or most marine pleasure craft. HFO also requires preheated storage and specialized handling. For Southeast Florida commercial customers running standard diesel engines, ULSD #2 remains the only practical choice. Exigo Fuels supplies ULSD diesel and marine diesel only.
Can diesel give you a rash?
Yes — direct, prolonged skin contact with diesel fuel can cause irritant contact dermatitis, presenting as redness, itching, dryness, cracking, and sometimes blistering. Diesel is classified as a skin irritant in OSHA Hazard Communication and has been associated with increased risk of skin cancer with chronic, unprotected exposure. Workers in fuel handling, equipment maintenance, marine, and construction should wear nitrile gloves, long sleeves, and eye protection, and wash skin promptly with soap and water if contact occurs. Diesel-soaked clothing should be removed and laundered separately. Anyone with persistent rash or chemical burn after exposure should seek medical evaluation. Exigo Fuels drivers follow OSHA-aligned PPE protocols on every delivery.
Who is the biggest supplier of fuel?
Globally, the largest fuel suppliers are Saudi Aramco, Sinopec, ExxonMobil, Shell, BP, Chevron, and TotalEnergies — vertically integrated majors that control upstream production, refining, and downstream distribution. In the United States, the largest fuel marketers and distributors include Pilot Flying J (TA-Pilot), Love's, Mansfield Energy, World Fuel Services, and Sunoco LP. Most regional commercial fuel delivery, however, is handled by independent jobbers and distributors that buy from refiner terminals and deliver to local fleets, generators, and marinas — the segment Exigo Fuels operates in for Southeast Florida. Choosing a regional specialist usually beats national chains on response time and pricing transparency.
Who is the largest fuel distributor in the US?
Mansfield Energy is generally cited as the largest independent fuel distributor in the United States by volume, moving roughly 3 billion gallons annually across all 50 states with a focus on bulk commercial, fleet, and emergency response fuel. Other top distributors include World Fuel Services (now Pilot Travel Centers / TA-Pilot), Pilot Company, Love's Travel Stops, and Sunoco LP. These national distributors typically partner with regional jobbers — independent operators like Exigo Fuels — for last-mile delivery in specific metro areas. For Southeast Florida commercial buyers, regional jobbers usually deliver faster response times and transparent pricing than national accounts.
What types of fuel do you deliver?
Exigo Fuels delivers a full range of petroleum products across Southeast Florida: ULSD #2 ultra-low sulfur diesel meeting ASTM D975 (clear/on-road and dyed/off-road grades), unleaded gasoline (87 regular, 89 mid-grade, 93 premium), premium marine diesel for boats and yachts, Recreational 90 ethanol-free gasoline for marine and small-engine use, off-road dyed diesel for construction equipment and standby generators, and on-road clear diesel for fleets. We also offer fuel polishing, tank cleaning, and on-site quality testing. All fuel is sourced from major refiners with documented BOLs and batch traceability. See /services/ for full product list.
What is ASTM D975 and why does it matter for diesel?
ASTM D975 is the international consensus specification for diesel fuel oils, published by ASTM International. It defines the chemical and physical properties — cetane number, sulfur content, flash point, distillation range, viscosity, lubricity — that diesel must meet for safe, efficient combustion in compression-ignition engines. ULSD (ultra-low sulfur diesel) under D975 caps sulfur at 15 ppm, which is required for EPA Tier 4 emissions compliance and to protect modern aftertreatment systems (DPF, SCR). Buying off-spec diesel risks engine damage, voided warranties, and emissions violations. Exigo Fuels delivers only ASTM D975-conformant ULSD; see our ASTM D975 guide.
What is the difference between dyed and clear diesel?
Clear diesel is on-road fuel sold with all federal and state road taxes included (about $0.61 per gallon in Florida combined) and is legal for use in any licensed highway vehicle. Dyed diesel is identical ULSD product treated at the terminal with red dye per IRS Section 4082; it is sold tax-exempt and restricted by federal law to off-road use only — generators, construction equipment, agricultural machinery, marine vessels, and stationary engines. Using dyed diesel in a highway vehicle is a federal violation with penalties starting at $1,000 per occurrence. Florida Department of Revenue and IRS conduct random tank dipping audits. See our full guide at dyed vs clear diesel.

Emergency & Hurricane Response (8)

Do you offer 24/7 emergency fuel delivery?
Yes. Exigo Fuels operates a 24/7/365 emergency dispatch line, including during hurricanes, tropical storms, and grid-out events. Our three-tier response prioritizes by urgency: Tier 1 (hospitals, life-safety, dialysis, telecom backbone) targets on-site arrival within 1 hour; Tier 2 (data centers, mission-critical commercial) within 2 hours; Tier 3 (standard fleet and generator emergencies) within 4 hours. Since 2023 we have maintained a 100% reliability record on emergency generator refueling for active commercial customers under contract. Note: emergency 1-hour and 2-hour dispatch is reserved for active contracted accounts; new customers are served on a scheduled-delivery basis. Call (305) 900-6725 to activate emergency response.
What is your hurricane preparedness program?
Our hurricane preparedness program for commercial accounts in Southeast Florida begins each May with a pre-season tank top-off and generator load-test fuel verification. During Florida's named-storm season (June 1 to November 30) we monitor NHC advisories and pre-position tankers, drivers, and dyed diesel inventory at our Hialeah staging area when a storm enters the cone. Customers on a Hurricane Priority Agreement get pre-storm top-offs at the 72-hour cone-of-uncertainty mark and post-storm priority dispatch as roads reopen. Past events handled include Hurricanes Irma, Dorian, and Ian. To enroll, contact our commercial team at (305) 900-6725.
How fast can you respond to a generator running out of fuel?
For active contracted customers, Exigo Fuels targets on-site arrival within 1 to 4 hours of an emergency call depending on response tier and address. Hospitals, dialysis centers, and life-safety facilities receive Tier 1 priority (1-hour target). Data centers and mission-critical commercial sites are Tier 2 (2-hour target). Standard commercial generators are Tier 3 (4-hour target). Response time is shorter for customers within 30 minutes of our Hialeah hub and during normal traffic windows; expect longer windows during active hurricane evacuation. We strongly recommend pre-arranging a service agreement before an emergency rather than calling for the first time during an outage. Activate at (305) 900-6725.
Can you deliver fuel during a hurricane?
Deliveries pause when the National Hurricane Center reports sustained winds above 39 mph or when local authorities close roads — driver and public safety override every dispatch. Outside those windows we operate continuously, including overnight and during tropical-storm-force conditions. Our hurricane SOP coordinates with Miami-Dade Emergency Management, Broward EOC, and Palm Beach EOC for road status and re-entry permits. Customers on a Hurricane Priority Agreement get top-offs in the pre-storm window (72 hours before landfall) and priority dispatch in the immediate post-storm period when generators are running and fuel demand spikes. Pre-arrange at (305) 900-6725.
Do you serve hospitals and life-safety facilities?
Yes. Exigo Fuels serves hospitals, dialysis clinics, surgery centers, assisted-living facilities, telecom switch sites, and other life-safety customers across Southeast Florida under Tier 1 emergency response (1-hour on-site target during active emergencies). We follow NFPA 110 generator fuel standards, maintain documented chain-of-custody on every delivery, and provide quarterly tank fuel quality testing where required. Critical infrastructure customers also receive priority during named-storm activations. We have served as a trusted subcontractor on critical-infrastructure fuel programs in Miami-Dade. Hospital procurement teams can request a service agreement at sales@exigofuels.com.
What documentation do you provide after an emergency delivery?
Every emergency delivery is documented with: a printed metered ticket showing gallons, fuel type, time, driver, and truck ID; a photographed dipstick reading before and after the fill (tank level verification); the refiner BOL (bill of lading) traceable to the source terminal; and an emailed digital invoice within 24 hours. For NFPA 110 Level 1 generator customers we add a fuel quality conformity statement (water, sediment, microbial growth assessment) on request. This documentation supports insurance claims, FEMA reimbursement, and regulatory audits following a hurricane or grid-out event. Records are retained for 7 years and accessible through your customer portal.
How do I prepare my generator tank for hurricane season?
Best-practice hurricane prep for a standby generator: top off to 100% by May 31; pull a fuel sample for water, particulates, and microbial growth (diesel bug) testing; replace fuel filters if they are more than 12 months old; run a load-bank test to confirm the unit will accept 80% nameplate load; verify the day-tank float and transfer-pump operation; confirm the supplier knows your tank fill location, tank capacity, and access requirements; pre-sign a Hurricane Priority Agreement with your fuel provider. Long-stored diesel that has not been polished in 12+ months should be filtered before the season. Exigo Fuels offers pre-season inspection and polishing — see /services/fuel-polishing/.
Can new customers get emergency dispatch during a hurricane?
During active emergencies, our 1-hour and 2-hour rapid dispatch is reserved for active contracted customers under a service agreement. New customers calling during an event are served on a scheduled-delivery basis as capacity allows, typically within 24 to 72 hours depending on event severity and queue depth. The reason: pre-staged trucks and dyed-diesel inventory go first to customers we have committed to. To avoid this gap, sign a service agreement before hurricane season — it costs nothing to enroll, locks in priority response, and includes a pre-season top-off. Enroll at (305) 900-6725 or sales@exigofuels.com.

Generator Refueling (6)

How to properly refuel a generator?
Best practice for refueling a diesel generator: shut down or transfer load before refueling on portable units; for permanent standby generators with dedicated tanks, refueling can be done with the unit running if the tank is sized and vented for it. Always ground the truck and tank, use a closed-system fill (no open buckets), monitor a calibrated meter, and stop at no more than 95% of tank capacity to allow for thermal expansion. After fueling, log the gallons added, take a dipstick reading, and inspect for leaks. Use only ULSD #2 meeting ASTM D975. For full SOP and Florida code references, see /services/generator-refueling/.
What is the 80% rule for generators?
The 80% rule for generators has two related meanings. First, on tank fills: never fill a fuel tank above 95%, and target 80% to 90% on smaller integral tanks to leave space for thermal expansion and to keep vapor venting safe. Second, on load: a continuously running generator should not be loaded above 80% of nameplate kW for extended periods — running near full load reduces engine life, increases wet-stacking risk on lightly loaded diesels, and cuts fuel efficiency. Most facility designers size generators so peak emergency load lands at 70% to 80% of nameplate. NFPA 110 and manufacturer guidance both align with this principle. Confirm with your generator OEM data sheet.
What is the 20/20/20 rule for generators?
The 20/20/20 rule is an industry rule of thumb for sizing a portable or backup generator: keep total connected load at 20% to 80% of nameplate, run for at least 20 minutes after starting before applying full load, and exercise the unit at 20% load for 20 minutes minimum during routine test runs. Some facility-management programs use 20/20/20 as a maintenance schedule: 20-minute exercise every 20 days at 20% load. The point is to prevent wet-stacking (unburned fuel buildup in the exhaust on under-loaded diesels), validate startup reliability, and exercise the engine at meaningful temperature. Refer to NFPA 110 for the regulatory framework on emergency generator testing.
How often do generators need to be refueled?
Standby generator refueling frequency depends on tank size, generator load, and run hours. A typical 100 kW commercial standby with a 250-gallon base tank consumes roughly 7 gallons per hour at 75% load — about 35 hours of runtime, or roughly one full refuel per major event. Larger units (500 kW+) with day tanks fed from a bulk storage tank may need bulk replenishment every 2 to 5 days during a sustained outage. Standby units that only exercise weekly need a top-off every 6 to 12 months to keep fuel fresh. Hospitals and data centers under NFPA 110 Level 1 maintain enough on-site fuel for 24-hour minimum runtime. See our generator program.
Can you refuel a generator while it is running?
For permanent standby generators with code-compliant fixed tanks, day-tank systems, and vented fill points: yes — refueling while the unit runs is standard practice during extended outages and is how data centers, hospitals, and telecom sites stay online for days. The driver uses a closed-system fill, a calibrated meter, and grounded equipment. For small portable generators with integral tanks, refueling while running is unsafe and prohibited by manufacturer guidance — gasoline vapors and hot exhaust can ignite. Always check the unit's service manual and follow NFPA 30 / 30A. See our detailed guide at /blog/can-you-refuel-generator-while-running-florida/.
Can you help with generator refueling for my building?
Yes. Exigo Fuels delivers scheduled and emergency generator refueling for commercial buildings, hospitals, data centers, telecom facilities, and high-rise residential complexes throughout Southeast Florida. Our scheduled program monitors fuel levels (manually or via remote tank-level telemetry where installed) and dispatches deliveries before tanks drop below threshold so backup power is always ready. For active outages, our 24/7 dispatch targets 1- to 2-hour on-site arrival for Tier 1 customers. We also offer fuel quality testing, polishing, and tank cleaning to keep stored diesel within ASTM D975 specs. Call (305) 900-6725 or see /services/generator-refueling/.

Off-Road & Construction (5)

Can anyone purchase off-road diesel?
No. Off-road (dyed) diesel is restricted by federal law — IRS Section 4082 — to legitimate off-highway uses: construction equipment, generators, agricultural machinery, marine vessels, and other stationary or non-licensed engines. To buy dyed diesel, the end user must use it only in qualifying off-road equipment and certify the use to the supplier. Buying dyed diesel and using it in a licensed highway vehicle is a federal violation with penalties of $1,000 minimum per occurrence (and per vehicle). Florida Department of Revenue and IRS Criminal Investigation conduct random tank dipping audits at construction sites and roadside fuel checks. Reputable suppliers (including Exigo Fuels) require a signed end-use certification before delivering dyed product.
Why is off-road diesel illegal?
Off-road diesel is not illegal — it is legal and standard for off-highway equipment, and it is the same ULSD product as on-road diesel chemically. What is illegal is using dyed off-road diesel in a licensed highway vehicle, because road-use fuel must carry federal and state road taxes that fund highway infrastructure. The red dye added at the terminal under IRS Section 4082 is a tax marker — its presence in a highway vehicle's fuel system is prima facie evidence of tax evasion. Penalties start at $1,000 per occurrence and escalate. Off-road diesel itself is fully legal for generators, construction, marine, and ag use. See our guide at /blog/dyed-diesel-vs-clear-diesel-florida-tax-guide/.
How much cheaper is off-road diesel?
Off-road dyed diesel is roughly $0.55 to $0.65 per gallon cheaper than clear on-road diesel in Florida — the savings come entirely from skipping federal excise tax ($0.244/gal) and Florida state diesel fuel tax (~$0.36/gal combined state and county). The base fuel cost, refining margin, and delivery margin are identical. For a 5,000-gallon-per-month construction operation, that is roughly $2,750 to $3,250 in monthly tax savings. Generator owners, marina operators, construction firms, and farms should always be on dyed diesel for off-road equipment. Exigo Fuels delivers both grades and tracks each separately on invoices. See /off-road-diesel-delivery/.
Do you fuel construction equipment on-site?
Yes. Exigo Fuels delivers wet-hose on-site fueling for construction equipment — excavators, loaders, dozers, generators, light towers, compactors, and tower cranes — across Southeast Florida. We dispatch tankers directly to active job sites, fueling each piece of equipment at the start of shift or overnight so equipment is full at first light. Each unit is metered and logged separately on the daily ticket, allowing project managers to allocate fuel cost to job codes. Off-road dyed diesel applies to qualifying equipment for tax savings of about $0.60 per gallon. Standing-order programs lock in pricing for the project duration. See /services/on-site-fuel-delivery/.
What documentation do I need to buy dyed off-road diesel?
To purchase dyed off-road diesel, federal IRS rules require the end user to certify in writing that the fuel will be used only in non-taxable off-road applications. Most suppliers (Exigo Fuels included) keep a one-time end-use certification on file per customer covering all subsequent deliveries; the form lists qualifying equipment and use cases. Resellers or fuel distributors need IRS Form 637 registration. There is no Florida Department of Revenue license needed for end users buying for their own off-road equipment. Maintain delivery records and equipment hour logs for at least three years to support an IRS or Florida DOR audit. Open an account at /services/fuel-wholesale/.

Fleet & Marine (5)

Do you offer fleet fueling programs?
Yes. Our fleet fueling program is built to eliminate the labor cost and downtime of sending vehicles to retail stations. Services include on-site bulk delivery to your yard or depot, wet-hose mobile fueling for scattered vehicles overnight, fuel management with per-vehicle and per-driver reporting, and consolidated weekly invoicing. Each fleet account gets a dedicated specialist who tunes delivery cadence, monitors consumption, and flags efficiency outliers. We serve transportation, construction, school bus systems, municipal vehicles, food service, and emergency-services fleets across Miami-Dade, Broward, and Palm Beach. Volume customers typically beat retail by $0.40 to $0.80 per gallon all-in. See /services/fleet-fueling/.
Do you deliver fuel directly to boats and yachts?
Yes. Exigo Fuels delivers premium marine diesel and Recreational 90 ethanol-free gasoline directly to docked vessels at private docks, marinas, yacht clubs, and commercial ports throughout Southeast Florida. Marine diesel is ULSD #2 meeting EPA Tier 4 marine standards and is dyed when sold tax-exempt for off-road marine use. Minimum order is 250 gallons. We handle vessels of all sizes — sport fishing, sailing yachts, motor yachts, sport-fishers, and commercial fishing — with careful spill-prevention procedures and absorbent booms deployed around the dock during transfer. Schedule at (305) 900-6725 or /services/boat-fueling/.
What marinas do you service?
We deliver to marinas, private docks, yacht clubs, and commercial waterfront across Miami-Dade, Broward, and Palm Beach counties. Frequent destinations include Williams Island Marina (Aventura), Fort Lauderdale Intracoastal Waterway marinas, Miami Beach Marina, Dinner Key Marina (Coconut Grove), Biscayne Bay private docks, Bahia Mar (Fort Lauderdale), Pier 66, Sunset Harbour, Old Port Cove (North Palm Beach), and Boca Grand Cay. We also serve commercial fishing docks and boatyards. If your marina or private dock is not on our regular route, call (305) 900-6725 — most accessible waterfront in the tri-county area can be reached by our fuel trucks with prior coordination of access and tide windows.
Do you provide reefer fueling for refrigerated trailers?
Yes. Exigo Fuels delivers dyed off-road diesel for refrigerated trailer (reefer) units at distribution centers, cold-chain warehouses, and produce yards across Southeast Florida. Reefer fueling is typically scheduled overnight or between dispatch waves so trailers stay cold without disrupting loading operations. Each unit is metered and logged by trailer number and driver. Off-road dyed product applies because reefer engines are off-highway under IRS rules — saving roughly $0.60 per gallon versus clear on-road diesel. We coordinate with yard supervisors on access and trailer ID lists. See /services/reefer-fueling/ or call (305) 900-6725.
Do you offer fuel cards for over-the-road fueling?
Yes. Exigo Fuels offers fuel card programs that pair on-site bulk delivery with over-the-road retail fueling at thousands of stations nationwide for fleets that operate beyond Florida or have drivers on long routes. Cards include per-driver and per-vehicle tracking, configurable purchase limits (gallons, dollars, day/time, station type), and consolidated weekly invoicing aligned with your bulk delivery account. The combined model lets fleet managers run cheap on-site fueling at the home yard while still supporting drivers on the road.
