Fuel trucks keep equipment running in the field without a trip back to the yard — critical for oilfield, construction, and agricultural operations across Texas and Louisiana. Two names dominate the conversation when fleet managers start shopping: STI (Service Trucks International) and Maintainer. Both build capable fuel service bodies, but the right choice depends on your chassis, your route, and where you’re buying. Here’s an honest side-by-side.

STI Fuel Trucks: Built for Texas Oilfield Fuel Routes
STI builds one of the most complete lube and fuel service body lineups on the market, and it shows in how their fuel trucks are configured. Multi-compartment tanks let one truck carry diesel, DEF, and hydraulic oil on the same route — a real time-saver for oilfield and pipeline crews running long service loops in the Permian Basin, Eagle Ford, and Gulf Coast.
STI Fuel Truck Strengths
- Texas-built — manufactured in Waco, TX and available locally through Star Truck Equipment in Wharton, TX
- Multi-compartment tank flexibility — diesel, DEF, and hydraulic oil in configurable combinations
- Pairs with STI’s full lube truck lineup for operators who need both fuel and lubrication service in one fleet
- Oilfield-proven — daily use across Texas and Louisiana energy corridors
- Local install and service — no shipping delays or long-distance warranty headaches
STI Fuel Truck Considerations
- Best matched to chassis cabs F-450 and up — not ideal for half-ton or 3/4-ton pickups
- Larger tank/pump packages push installed cost toward the higher end
- Peak season lead times can stretch during oilfield demand spikes
Maintainer Fuel Trucks: Ag and Utility Fleet Standard
Maintainer has built service and fuel truck bodies for over 60 years, with a strong following among agricultural equipment dealers and county/utility fleets, especially in the Midwest. Their fuel truck configurations are dependable and well-proven for operations that refuel heavy equipment on set routes rather than remote oilfield locations.
Maintainer Fuel Truck Strengths
- Long manufacturing track record — 60+ years building service and fuel bodies
- Heavy chassis support — options through Class 6–7 medium duty trucks
- Established reputation with ag equipment dealerships and municipal fleets
Maintainer Fuel Truck Considerations
- Limited dealer support in South Texas and Louisiana compared to STI
- Premium pricing on comparable tank/pump configurations
- Special-order lead times can be significant for popular configurations
