Title: Save Big on Fuel – What Every Pressure Washing Pro Should Know About Non-Road Diesel
If you’re in the pressure washing business and you're not already taking advantage of
non-road diesel, you could be leaving serious money on the table.
Here’s the deal: Every gallon of diesel you pump at the station for on-road use is hit with both
federal and state road taxes. But if that fuel is going into equipment that doesn’t touch a public road — like hot water pressure washers, generators, or anything stationary — you could avoid paying those taxes entirely.
How Much Can You Save?
Across the U.S., the average road fuel tax adds up to
about 55–60 cents per gallon — some states even top
$1.00 per gallon. That means if your crew burns through 100 gallons of diesel a week in equipment, you're potentially wasting
$50–$100 every single week.
Hot Water Units = Higher Fuel Burn
Those of us running
hot water units know how quickly fuel disappears on long commercial jobs. It’s not uncommon to burn through
half or more of your fuel in your burners alone during overnight shifts. That’s all fuel that qualifies as
non-road usage.
Two Ways to Take Advantage
1. Set Up a Fueling Station at Your Shop
If you have a fleet and a fixed location, consider setting up a small
fuel tank on-site. Fuel delivery services can bring
dyed diesel (non-taxed, off-road fuel) right to your shop. This is perfectly legal as long as you’re not putting it in vehicles that drive on public roads.

Important: Non-road diesel (also called "dyed diesel") is
illegal to use in any vehicle that travels on public streets. It’s meant strictly for equipment.
2. Use Designated Non-Road Fueling Stations
Some cities have stations that sell diesel
specifically for equipment use. These locations do
not include the road tax in their pricing. Ask your local fuel supplier or check state energy websites for approved fueling points. They're especially common in agricultural and industrial zones.
Documentation Matters
Keep accurate records. If you’re ever audited, you’ll want to show:
- Where the fuel went (equipment, not trucks)
- How much you used
- Where you bought it
Bottom Line
If half your diesel usage is going into machines that
never touch the street, you should not be paying road taxes on that fuel.
The savings can add up fast:
- 100 gallons/week = $55–$60 saved
- 400 gallons/month = $220–$240 saved
- 5,000 gallons/year = $2,750–$3,000+ saved
This is an
easy win for pressure washing companies looking to cut costs without cutting corners.
