Fuel Types We Deliver
We offer multiple refueling options to meet the needs of different industries, applications, and compliance requirements.
- Diesel Fuel Delivery On-road diesel remains essential for fleets, transportation, and modern diesel-powered equipment. Our mobile fuel trucks deliver diesel directly to your vehicles, machinery, or tanks, eliminating unnecessary trips and downtime.
- Dyed (Off-Road) Diesel For construction, agricultural, and industrial equipment that operates off public roads, we deliver dyed diesel directly to your job site. Also known as off-road or red diesel, this fuel is ideal for heavy equipment, generators, and stationary engines.
- Diesel Exhaust Fluid (DEF) We also supply DEF delivery to support emissions-compliant diesel engines. Whether you need DEF delivered directly to equipment or bulk DEF supplied to your site, we help keep your fleet operating efficiently and within regulatory standards.
On-Site Fuel Cells for Reliable Supply
For operations that burn fuel daily, having diesel delivered is only part of the equation. One Call Rentals also provides portable on-site fuel cells with pumps in 250-gallon, 500-gallon, and 1,000-gallon options, giving your crew a dependable on-site supply without relying on constant refueling runs.
These fuel cells are ideal for construction sites, fleet yards, remote projects, and any location where downtime or fuel runs create delays.
Benefits of adding a fuel cell to your refueling plan:
- Reduced delivery frequency: Larger on-site capacity means fewer deliveries and less scheduling overhead.
- Assured on-site supply: Keep fuel available for equipment, generators, and vehicles throughout the workweek.
- Faster daily operations: Fuel on-site instead of sending operators off-site mid-shift.
- Scalable to your usage: Choose the right size based on burn rate, crew size, and project duration.
- Cleaner, simpler logistics: One partner can support both the fuel delivery and on-site storage setup.
If you’re not sure which size fuel cell fits your operation, our team can recommend the best option based on your equipment mix, expected run times, and delivery cadence.
