How Fuel Gets to You

Mobile fueling or bulk delivery: which fits your Colorado site?

Three delivery formats. We’ll quote whichever fits your volume, site access and cost target.

Wet-Hose Fueling

Mobile fleet fueling

Overnight or day shift, fuel direct to each tank

A driver pulls into your yard after hours, fuels every truck or piece of equipment directly, logs each fill, and clears out before your crews arrive. No staff required on site.

Best for: Trucking fleets, delivery yards, rental fleets and service vehicles.

Tank Wagon Delivery

On-site tank fills

20 – 4,400 gallons per drop · same-day or scheduled

A smaller delivery truck fills your day tank, jobsite bulk tank or generator. The flexible option when volume varies or site access is tight.

Best for: Construction sites, generator refills, day tanks and smaller bulk storage.

Transport Load

Bulk transport delivery

Full transport loads to 7,500+ gallons · scheduled

Tractor-trailer delivery straight into large bulk storage. The lowest cost per gallon for high-volume buyers.

Best for: Data centers, large industrial sites, agriculture and rail yards.

Colorado Diesel Taxes

What diesel tax costs per gallon across Colorado

Colorado's combined on-road diesel tax is $0.6050 per gallon, below the $0.6052 national average.

$0.6050

On-road (clear) diesel, per gallon

$0.0270

Off-road (dyed) diesel, per gallon

$578.00

Tax difference per 1,000 gallons

20th

Highest on-road rate of 50 (49 states + D.C.)

Dyed diesel is nearly tax-exempt here ($0.0270 per gallon), so for equipment that never runs on public roads, dyed saves about $0.5780 per gallon, or $578.00 on every 1,000 gallons. Rates include federal and state per-gallon taxes and fees as of October 5, 2026; sales and local taxes are extra. Not tax advice. See every state's breakdown →
