Exigo Fuels Blog
Operational analysis, cost breakdowns, specification guides, and hurricane-season playbooks from the Exigo Fuels dispatch team. Written for fleet managers, facility directors, generator operators, marine bunker buyers, and construction site superintendents who buy commercial diesel and gasoline in Southeast Florida.
The Exigo Fuels blog exists for one audience: operators responsible for keeping fuel flowing across a fleet, a facility, or a critical site in Miami-Dade, Broward, or Palm Beach counties.
Every guide is written or reviewed by someone on our dispatch, driver, or account-management team who has handled the scenario we are documenting — whether that is a hospital generator top-up during a substation outage, a weekend reefer fueling run to a cold-storage warehouse in Medley, an off-road dyed diesel drop at a Brightline corridor construction site, or a fleet transition from retail cards to on-site delivery.
Articles cite their sources (EPA, DOT, NFPA, ASTM, USCG, IRS, FDACS, Florida DEP) so a compliance officer or facility engineer can audit any claim. Pricing examples use conservative public benchmarks (AAA Florida averages, EIA retail data, OPIS rack postings) with assumptions stated explicitly.
Where a topic touches a service we sell, we link to the relevant service page; where it does not (DEF distribution, residential fuel storage, retail fueling apps), we say so plainly. If a topic does not help you make a specific operational or purchasing decision, we do not publish it.
Commercial fuel pricing is more transparent than retail pump pricing — but only if you know what to look at. These guides break down rack-indexed wholesale pricing, the volume thresholds where bulk delivery starts paying back, fleet-wide cost per gallon and per mile, and the head-to-head economics of mobile fuel delivery versus fuel cards. Use them when you are comparing quotes, building a fueling-program business case, or deciding whether to switch your Southeast Florida fleet from retail stations to wholesale delivery.
Commercial fuel pricing is more transparent than retail, but it moves daily and depends on more than just the per-gallon number. Here is how to read a quote, what should be itemized, and where the real savings are.

Read full articleFuel specs are not interchangeable, and the regulatory framework around diesel and gasoline in Florida is layered — IRS §4082 for off-road dyed diesel, ASTM D975 for ULSD chemistry, EPA Tier 4 for aftertreatment, FDACS for meter calibration. These guides cover what the specs mean operationally, when each fuel type is the right choice, and how to read batch documentation so you can audit what you actually buy. Written for fleet managers, compliance officers, and facility engineers in Southeast Florida.
Diesel and gasoline are not interchangeable. Here is the engineering, economics, and Florida-specific framework for choosing the right fuel platform — including per-mile and per-hour cost math, aftertreatment differences, and a decision matrix by fleet type.
Read full articleASTM D975 is the one diesel spec that matters on every commercial invoice — the 15 ppm sulfur limit alone is what keeps Tier 4 engines alive. Here is what the spec covers, why it matters, and how to verify your supplier.
Read full articleDyed diesel is clear ULSD with a red dye marking it tax-exempt — same ASTM D975 fuel, $0.24-$0.58 cheaper per gallon. Here is who can legally use it in Florida, why it is illegal on public roads under IRS §4082, and how the construction, agriculture, marine, and generator operators who qualify order it.
Read full articleOff-road dyed diesel runs $0.30 to $0.55 per gallon below clear ULSD in Florida — and using it in a road-registered vehicle starts at $1,000 per violation under IRS §6715. Here are the 2026 price ranges, the legal use cases, and the federal + state + local enforcement framework.
Read full articleHow a commercial fuel delivery actually runs — from quote and dispatch through metered transfer and invoice — and the response-time tiers that govern when fuel arrives. These operations guides explain the equipment (DOT-spec tankers, FDACS-sealed meters, NFPA 30A grounding), the safety procedures, and the timing benchmarks you should expect from a credible Southeast Florida supplier. Use them to set internal expectations, train site personnel, and evaluate suppliers during a procurement.
Mobile fuel delivery brings ASTM D975 diesel and gasoline directly to your site in DOT-compliant tankers. Here is the full six-step process, the equipment, the safety and compliance framework, and the cost structure — plus when it fits and when it does not.

Read full articleFlorida operates under a six-month Atlantic hurricane season every year, and commercial fuel readiness during that window is fundamentally different from the rest of the calendar. These guides document the pre-storm and post-storm playbooks we use internally — generator runtime sizing, NFPA 30 storage compliance, the 72h/48h/24h pre-landfall checklists, and the contracted dispatch protocols that critical infrastructure (hospitals, data centers, public safety) operates under during named-storm activation.
A step-by-step Florida hurricane fuel readiness playbook — pre-season generator load tests, runtime sizing math, NFPA 30 and Florida DEP compliance, and the 72h/48h/24h pre-landfall checklists we use internally.

Bulk fuel delivery pricing in Florida depends on three things: volume, fuel type, and delivery distance. Here is the exact cost breakdown for 2026 — per-gallon rates, minimum orders, and what drives the price up or down.

Read full articleOur editorial voice is deliberately operational rather than promotional. Cost analysis pieces break down the economics of on-site versus retail fueling, volume- based pricing tiers, and recovered driver time — with methodology transparent enough that you can reproduce the math on your own fleet. Fuel-technology guides cover diesel specifications (ASTM D975, ULSD chemistry, biodiesel blends), gasoline grades and REC-90 ethanol-free applications, fuel polishing and contamination diagnostics, and storage tank maintenance under NFPA 30 and Florida DEP rules.
Safety and compliance guides explain the regulations that shape commercial fuel delivery — NFPA 110 for standby generator systems, DOT Hazmat rules under 49 CFR Parts 171-180 for fuel transport, FDACS weights-and-measures for meter sealing, and EPA SPCC under 40 CFR Part 112 for on-site storage above 1,320 gallons. Hurricane preparedness and emergency response articles document what we have learned from each Atlantic storm season since 2023, including the contracted dispatch protocols we operate under for critical infrastructure.
For facility planning, we recommend reading the relevant industry guide first (see our industries overview), then the matching service guide on services, before requesting a quote. For fleet conversion analysis, start with the pricing cluster above and run your own numbers in the fuel cost calculator.
For fuel-spec questions, the diesel vs gasoline and ASTM D975 guides cover most decision points; for off-road dyed diesel tax handling, the IRS §4082 guide covers eligibility, penalties, and tank-mixing rules. For hurricane season, the 2026 preparedness guide is the operational playbook we use internally — including the 72h/48h/24h pre-landfall checklists and generator runtime sizing math.
Most operational specifics in these guides are tuned to commercial buyers in Miami-Dade, Broward, and Palm Beach counties — the area Exigo Fuels services directly out of our Hialeah headquarters. Compliance frameworks (DOT, EPA, NFPA, ASTM, IRS) apply nationally, so the specification and tax content carries cleanly to other states.
Pricing benchmarks (OPIS rack averages, Florida state fuel tax rates, Florida DEP storage thresholds) reflect Florida market conditions and should be adapted before applying outside the state. Hurricane preparedness content is explicitly Florida-focused — Atlantic basin season timing, Florida DEM coordination, Southeast Florida evacuation routes — and may not translate to Gulf-coast or non-coastal operations without adaptation.
The best articles come from reader questions. If there is a topic you want covered that is not on this blog yet — a specific compliance scenario, a fuel-quality diagnostic, a fleet-conversion case study, an industry-specific deep dive — email our team at content@exigofuels.com and we will write it.
