If your operation depends on keeping heavy equipment running in the field, a purpose-built lube truck or fuel service body isn’t a luxury — it’s essential. Service Trucks International (STI) has built a well-earned reputation for manufacturing some of the toughest lube trucks and fuel service bodies in the industry, and at Star Truck Equipment in Wharton, TX, we stock and upfit STI bodies for crews across Texas and Louisiana.
What Is an STI Lube Truck?
An STI lube truck is a fully outfitted service vehicle designed to deliver lubrication, oil, and maintenance services directly to equipment in the field. Instead of hauling your machinery back to a shop, the shop comes to the machine. STI lube bodies are mounted on medium-duty chassis — typically Ford F-550, Ram 5500, or International HV platforms — and can be customized for a wide range of service applications.
These aren’t generic utility bodies with a few extra tanks bolted on. STI engineers each lube truck body from the ground up with the operator in mind: stainless-steel plumbing, precision-welded compartment framing, high-capacity oil and fluid tanks, reel mounts, and generator provisions. The result is a rig that can handle oil changes, greasing, and preventive maintenance on dozers, excavators, haul trucks, and other heavy iron — all without leaving the job site.
STI Lube Truck Key Features
- Multiple fluid tank configurations — engine oil, hydraulic fluid, gear oil, grease, fresh coolant, and waste tanks available in various capacities
- Heavy-duty compartments — lockable steel doors with full-length piano hinges for maximum storage organization
- Built-in reel mounts — support hose reels for oil, grease, and air delivery
- Generator-ready — provisions for onboard power to run lighting, air compressors, or electric reels
- Corrosion-resistant plumbing — stainless-steel fluid lines and fittings that hold up in oilfield and coastal environments
- Custom tank sizing — STI can configure tank volumes to match your specific shift requirements and fluid volume needs
STI Fuel Service Bodies
Alongside lube trucks, STI manufactures dedicated fuel service bodies — sometimes called fuel and lube combos — designed for fleet fueling and on-site fuel delivery. These bodies feature integrated fuel tanks (typically aluminum or steel), dual-pump systems for DEF and diesel delivery, and secure lockable compartments for hoses, nozzles, and accessories.
For oilfield crews in West Texas, the Permian Basin, or the Louisiana bayou country, an STI fuel service body eliminates daily fuel hauls and reduces equipment downtime. Your crew fuels up on-site and moves on — no waiting, no trips back to base.
STI fuel service bodies are often paired with crane bodies for maximum utility. If you need fuel delivery and lifting capability on a single truck, check out our crane bodies and STI crane body pages for combo configurations.
Who Uses STI Lube and Fuel Trucks?
STI lube trucks and fuel service bodies serve a wide range of industries across Texas and Louisiana:
- Oilfield services — Permian Basin, Eagle Ford, and Louisiana shale operations that need field lubrication and fuel delivery for drilling equipment
- Construction fleets — general contractors and earthmoving companies maintaining bulldozers, graders, and compactors on remote sites
- Municipal and county road departments — keeping road maintenance equipment in service without trips back to the yard
- Mining and aggregates — quarry and pit operations needing consistent lubrication schedules on crushers and loaders
- Agriculture — large farming operations in South Texas maintaining combines, tractors, and irrigation pumps during planting and harvest seasons
How STI Compares to the Competition
STI is often compared to brands like Maintainer, Knapheide, and Stellar in the lube and fuel truck category. While all three make capable products, STI differentiates itself with deeply customizable tank and compartment configurations, a strong domestic dealer network, and competitive pricing on fully-spec’d units. For a head-to-head breakdown, read our STI vs Maintainer service bodies comparison.
