RV Fuel Efficiency: A Few Tips To Save You Money at the Gas Pump

Posted On: July 9, 2015

RVers, like those of us at Guaranty RV, pay attention to gas prices, and we know that 2015 is the year to take that dream vacation or road trip you’ve been putting off, because fuel prices are as low as they’ve been in ages. Just to give us that extra nudge in the vacation direction, AAA’s Monthly Gas Price Report for July tells us that the national average price of gas this month is the lowest it’s been in six years. That’s cause for celebration, but it doesn’t mean that you shouldn’t be concerned about how much you’re spending at the gas station. Sure, it’s less to fill up your tank than it was a year ago, but the cost of fuel to drive a motorhome or tow a travel trailer, fifth wheel or toy hauler can still be a bigger price tag than you’d like. Luckily, there are good ways to get the most fuel efficiency possible out of your RV, so you can stay out on the road, at the coast or in the woods for as long as you want. Whether you’re looking for some pointers on how to get the most out of the RV you already own, or you’re in the market for the most fuel efficient RV on the road, we’ve got some tips.

Tips For Better Fuel Efficiency: Keep Up On Maintenance


We’ve said this before, and we hear it from RV manufacturers all the time: the #1 thing you can do to get the best fuel efficiency out of your motorhome or tow vehicle is to perform regular maintenance. The camping experts, KOA, created a graph that gives you a visual of the largest culprits in fuel efficiency loss in RVs, and it was no surprise to us that three out of the four biggest culprits are dirty air filters, out of tune engines and faulty emissions. According to their research, a finely tuned motorhome or tow vehicle engine can save you up to 20% in fuel efficiency. Replacing an old oxygen sensor could make your RV a whopping 40% more efficient. A clean air filter can improve your RV’s fuel economy by up to 10%. You can get 3% better fuel efficiency by keeping your tires properly rotated and adjusting your tire pressure. No matter how you look at it, keeping up on your motorhome or tow vehicle’s maintenance schedule saves you money at the gas pump.

At Guaranty, we make it easy to keep track of your maintenance schedule. Download our easy-to-use RV Owner app to your smartphone. You can get the Android app from the Google Play Store, and the iPhone app is currently available in your iTunes App Store. Just look up Guaranty RV. Set RV Owner with your RV’s recommended service plan, along with your mileage, and it will automatically alert you when it’s time to check maintenance items off your list. You can check off the services you’ve completed as you go, delete ones you don’t intend to do, or even schedule an appointment with our RV Service Center directly from the app. Just set it and forget it; it’s as simple as that.

Driving Tips for the Best Gas Mileage: Staying at a Consistent Speed is Key


The other major gas-eating culprit in that KOA study is speeding. Their research corresponds with what many other RV manufacturers and RVers have found—55 to 60 miles per hour is the “sweet spot” for RV fuel efficiency. According to this study, every five miles per hour that you speed over that sweet spot costs you as much as ten cents more per gallon! So even if fuel prices are going down, your driving habits could be keeping your cost at the pump much higher.

Other driving tips include:
  • Use your overdrive gears whenever you can.
  • Utilize your cruise control so that you’re staying at a consistent speed.
  • If you’re idling somewhere for more than two or three minutes, turn off your engine.
  • Avoid rapidly speeding up or slowing down; build speed slowly and steadily.
  • Keep your windows rolled up while on the highway.
  • Plan in advance for best RV routes and less traffic.
  • Leave plenty of time to reach your destination, so you don’t have to speed.


One More Tip For Getting the Best Fuel Efficiency: Don’t Overpack


It’s easy in modern RVs to overpack, particularly in motorhomes and fifth wheels that offer such a wealth of storage. The problem is that extra weight makes for lousy gas mileage, and it’s not just the extra weight, but how it’s distributed throughout your RV. Take a look at your RV’s Gross Vehicle Weight Rating (GVWR) and stick to that, even if you can load in more. Also, spread the weight throughout the storage options in your RV so you’re not overloaded on one side or one end. Think about what you can leave at home. For instance, can you buy firewood near your destination rather than hauling it in your RV?

Another thing to consider in terms of RV weight is your water and waste tanks. If you’re going to a campground with full hookups, don’t fill your water tanks before you go; just fill up at the campsite and save yourself some mileage on the road. Remember, one gallon of water weighs eight pounds, and that quickly adds up. Similarly, dump and flush your waste tanks as soon as you can when you’re done camping, so you’re not hauling home the extra weight and impacting your fuel efficiency.
