Exigo Fuels Blog
Operational analysis, cost breakdowns, and industry guides from the Exigo Fuels team. Written for fleet managers, facility directors, and anyone buying commercial fuel in Southeast Florida.
Dyed 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 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 articleCommercial 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 articleThe Exigo Fuels blog exists for one audience: operators who are responsible for keeping fuel flowing across a fleet, a facility, or a critical site in Southeast Florida. Our editorial voice is deliberately operational rather than promotional. Every guide is written by or reviewed by someone on our dispatch, driver, or account-management team who has handled the scenario we're describing — whether that's a hospital generator top-up during a substation outage, a weekend reefer fueling run to a cold-storage warehouse in Medley, or a fleet transition from retail cards to on-site delivery. If the topic doesn't help you make a specific operational or purchasing decision, we don't publish it.
Our content spans four broad categories. Safety and compliance guides explain the regulations that shape fuel delivery in Florida — NFPA 110 for standby generator systems, DOT Hazmat rules for fuel transport, FDACS weights-and-measures requirements, SPCC for on-site storage, and USCG coordination for marine bunker operations. 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. Hurricane preparedness and emergency response articles document what we've learned from each Atlantic storm season since 2023, including the checklist we use internally during the pre-landfall queue.
Every article cites its sources: the EPA, DOT, NFPA, ASTM, and USCG regulations that we work under every day. Where we offer pricing examples, we use conservative public benchmarks (AAA Florida averages, EIA retail price data) and explicitly state the assumptions behind any savings calculations. We do not publish content that we cannot technically verify. 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. If you want a specific topic covered that isn't already on the blog, email dispatch and we'll write it — the best articles come from reader questions.
