What Makes RVs Use More or Less Gas?
Many things can change how much gas your RV uses:
- Engine type: Diesel engines get about 25% better mileage than gas engines
- How heavy the RV is: More weight = more gas
- Towing: Pulling a car or boat makes you use more gas
- Wind: Driving against the wind uses more fuel
- Speed: Going faster burns more gas
- Hills: Going up mountains uses much more fuel
How Much Fuel Does an RV Generator Use?
Your RV generator also needs fuel. Here’s what to know:
- Gas generators use about 0.75 gallons per hour
- Propane generators use about 3.45 gallons per hour
So if you run your generator for 4 hours, that’s 3 extra gallons of gas you’ll use!
2025 RV Gas Price Outlook
Good news for RV owners! Gas prices are looking a bit better:
- 2025 forecast: $3.22 per gallon (national average)
- Down from $3.33 in 2024
This might help you save money on your next trip.
How to Figure Out Gas Costs for Your Trip
Want to know how much your RV trip will cost in gas? Here’s a simple way to figure it out:
- Find out how many miles you’ll drive
- Divide by your RV’s MPG
- Multiply by the price of gas
For example: A 1,000-mile trip in a Class C RV that gets 10 MPG at $3.22 per gallon would cost:
1,000 ÷ 10 = 100 gallons
100 gallons × $3.22 = $322 for the whole trip
You can also use an online RV fuel calculator to make this even easier!
Ways to Use Less Gas in Your RV
Want to save money? Here are simple tips:
- Drive slower: Going 55 mph instead of 70 can save lots of gas
- Take out heavy stuff: Less weight means less gas
- Check your tires: Make sure they have the right air
- Use apps like GasBuddy to find cheaper gas
- Plan your route to avoid steep hills when possible
- Turn off your generator when you don’t need it
