Diesel Needs 37.5% Better Economy Just to Break Even on Fuel

At the EIA's latest averages, diesel is $5.60 a gallon against $4.07 for gasoline. That is one of the few numbers in an RV fleet budget anybody actually publishes.

Why this cost guide has fewer prices than it used to

An earlier version of this page carried thirty-five dollar ranges. None of them was sourced, because there is no published rate card for multi-unit RV rental, and the venues these deployments go to overwhelmingly do not publish their own charges either.

What follows separates the lines you can fix today, the lines you can calculate from published data, and the lines nobody publishes at all. That is less satisfying than a table of averages and considerably more useful when you have to defend a number.

Fuel is the line you can calculate rather than guess

The U.S. Energy Information Administration publishes national average retail fuel prices weekly. For the week ending August 31, 2026 it put on-highway diesel at $5.60 per gallon and regular gasoline at $4.07.

Divide the price by the vehicle's economy and you have a cost per mile. Multiply that by the round-trip distance, because a delivery run comes back whether or not the coach does.

EconomyDiesel per mileGasoline per mileDiesel, 400-mile round trip
6 mpg$0.933$0.678$373.27
7 mpg$0.800$0.582$319.94
8 mpg$0.700$0.509$279.95
9 mpg$0.622$0.452$248.84
10 mpg$0.560$0.407$223.96
11 mpg$0.509$0.370$203.60
12 mpg$0.467$0.339$186.63

The economy figure is yours to supply, because it depends on the unit, the load and the terrain, and we are not going to invent one. Ask the supplier what the specific unit returns. The prices in that table are published; the mpg is the input you bring.

The diesel assumption that costs money

Diesel units carry a reputation for being cheaper to run, and on a long enough view there are real arguments about durability and torque. On fuel cost per mile, at these prices, the arithmetic does not support it on its own.

Diesel at $5.60 against gasoline at $4.07 is roughly 37.5% more per gallon. To break even on fuel cost per mile, the diesel unit has to return about 37.5% more miles per gallon. A gasoline unit at 8 mpg is matched by a diesel at roughly 11 mpg, not at 9.

What it costs to assume

On a deployment with real mileage, choosing diesel on the belief that it is automatically cheaper to fuel, when the actual economy gap is two or three miles per gallon rather than 3.0, means paying more per mile for the whole job. Ask for both units' real economy figures and run the division before deciding. It takes a minute and the prices are published weekly.

One caveat worth stating: these are national averages and fuel prices move weekly and regionally. Re-check the EIA release for your travel window rather than relying on the figures on this page, and note the date this page was updated.

The lines nobody publishes

Across the venues we have checked while writing this site, the pattern is consistent and it is worth stating plainly, because it changes how a budget should be presented.

Daytona International Speedway publishes no campsite rate. SoFi Stadium says only that "Parking fees will vary based on each event." Arrowhead and Buffalo require passes purchased in advance without stating a figure. Lambeau routes RVs to a third-party operator. Coachella publishes no camping price. Neither CES nor the Las Vegas venues publish a vehicle exhibit rate.

How to present a budget with real holes in it

Give the fixed number, give the calculated number with its workings, and name each unpublished line explicitly with who you will get it from and when. A budget with four labelled open lines survives scrutiny. A budget with a tidy all-in figure built on someone's blog estimate does not survive the first invoice.

The three lines most often under-counted

The return leg. A delivery is a round trip in fuel and driver hours even when the brief is one way. The table above prices 400 miles for a 200-mile job for exactly this reason.

Waste service. Most venues we have checked provide no sewer connection. Bonnaroo publishes $75 per mobile pump service and states "There will not be any hookups or dumping areas." Daytona lists pump-out as a paid service in most of its campgrounds and offers none at all in one. That is a recurring line driven by tank capacity and headcount, not a one-off.

The driver across the deployment. If a unit needs repositioning mid-event, it needs the same licence class as the delivery did. Budgeting a driver for drop-off only leaves the unit stranded wherever it was first placed.

What most people get wrong: comparing per-unit instead of per-deployment

Rental rates are quoted per unit per day, so that is how people compare suppliers. It is the wrong unit of comparison once delivery, fuel, waste and drivers are in play, because those scale differently. Fuel and driver time scale with distance and moves, not with unit count. Waste scales with headcount and nights.

A slightly higher day rate from a supplier with units closer to the site can be the cheaper deployment once the round-trip mileage is priced. Ask where the units are actually coming from before comparing day rates, because that answer is worth more than the rate difference on any job with real distance in it.

"I would rather hand somebody a budget with four blanks in it and my name against who fills each one, than a clean total I cannot stand behind. The fuel I can work out in front of them, because the EIA publishes the price every week. The campsite at Daytona I cannot, because Daytona does not publish it. Pretending otherwise is how people end up explaining a variance to their finance team."

Build the budget in this order

  1. Get a firm unit quote for exact dates. This is your anchor.
  2. Ask where the units are staged, and calculate round-trip mileage from there.
  3. Ask the supplier for each unit's real fuel economy, then divide the current EIA price by it.
  4. Decide whether the driver is needed for delivery only or across the deployment.
  5. Work out tank capacity against headcount and nights to size the waste service line.
  6. Name every venue line you cannot price, with who you will get it from and when.
  7. Re-check the EIA fuel release close to travel, since these are weekly national averages.

Frequently Asked Questions

Is a diesel RV cheaper to run than a gasoline one?

Not automatically, and at present prices the gap is wide. The U.S. Energy Information Administration put on-highway diesel at $5.599 per gallon and regular gasoline at $4.071 for the week ending August 31, 2026. Diesel is therefore about 37.5% more expensive per gallon, so a diesel unit needs roughly 37.5% better fuel economy simply to match a gasoline unit on fuel cost per mile. A gasoline unit returning 8 mpg is matched by a diesel returning about 11 mpg.

How much does RV fleet rental cost?

No manufacturer, association or venue publishes a rate card for multi-unit RV rental, so any single all-in figure is an estimate rather than a published price. What can be quoted firmly for stated dates is the unit rental itself. Fuel can be calculated from published EIA prices once you know the distance and the vehicle’s economy. Venue costs, permits and waste services are typically unpublished until you buy them.

How do you calculate RV delivery fuel cost?

Divide the current fuel price by the vehicle's miles per gallon to get cost per mile, then multiply by the round-trip distance, because a delivery usually returns. At the EIA's the week ending August 31, 2026 diesel average of $5.599, a unit returning 8 mpg costs about $0.700 per mile, so a 200-mile delivery run out and back is roughly $279.95 in fuel before any labour.

What costs are usually missing from an RV fleet budget?

Waste service, venue credentials and the return leg. Most venues we have checked provide no sewer hookup, so pump-out is a recurring paid service; venue oversized-vehicle passes are rarely priced publicly; and delivery mileage is a round trip even when the job is one way. A licensed driver across the whole deployment, rather than just for delivery, is the other line that is regularly under-counted.
