How mobile diesel delivery pricing works
Every quote has two components: the fuel and the delivery.
The fuel is priced at a competitive per-gallon market rate that changes daily — sometimes dramatically. In one recent week, our delivered price for on-road diesel moved from $3.69 to $4.69 per gallon, and off-road dyed diesel moved from $3.09 to $4.09. That's not a pricing strategy; that's the diesel market. Any company quoting you a fixed per-gallon price weeks in advance is either padding it heavily or planning to renegotiate.
The delivery fee covers the truck, the driver, and the time your job takes. It ranges from zero to roughly $1,000, and the structure is often negotiated per account. Some clients prefer a single per-gallon number with no separate line item — in that case the delivery cost is built into the gallon price. Same math, different invoice.
Current price ranges in Denver
| Item | Recent delivered range | Notes |
|---|---|---|
| On-road (clear) diesel | $3.69 – $4.69 / gal | Moves daily with the market |
| Off-road (dyed) diesel | $3.09 – $4.09 / gal | No road taxes; off-road equipment only |
| DEF (diesel exhaust fluid) | $2.50 – $3.00 / gal | Delivered |
| Delivery fee | $0 – ~$1,000 | See factors below; often fused into gallon price on volume accounts |
| Emergency / after-hours | ~2× the delivery fee | Fuel priced at market rate as usual |
Ranges reflect what our Denver-metro customers have recently paid. Your quote depends on the day's market and your site.
What determines your delivery fee
Four factors move the fee up or down:
- Volume. The biggest lever. The more gallons in one stop, the lower the fee per delivery — small top-offs carry the highest fees because the truck and driver cost the same whether we pump 80 gallons or 800.
- Distance. Miles traveled from our service area to your site.
- Site difficulty. Access, terrain, and how the job eats time: a paved lot with one tank is one thing; a muddy site where the truck can't get within hose distance of six scattered machines is another.
- Equipment count. Fueling one generator is faster than wet-hosing fifteen pieces of equipment across a site. Time is part of the fee.
Scheduled vs. emergency delivery pricing
Emergency fuel delivery costs roughly double the standard delivery fee, and it's worth understanding why. A 2am emergency call means waking a dispatcher, reaching a driver, prepping a truck, and deploying to your site on a clock where every minute matters — usually because a generator is about to run dry or a crew can't start. The fuel itself is still priced at market rate; you're paying for guaranteed middle-of-the-night deployment. If your operation can't tolerate downtime, a scheduled recurring delivery is always cheaper than an emergency call.
How to get an accurate quote fast
Have four things ready when you call: roughly how many gallons you need, the site address, what we're fueling (tanks, generators, equipment — and how many), and your timing. With those, a quote takes minutes. We serve the Denver metro in English y en Español: (720) 736-1614.
