Your RV Gas Mileage – 5 Tips To Make It Better

If you are concerned about your RV gas mileage, you are in good company. A lot of RVers have the subject of RV fuel economy on their mind at times. And no wonder, since RV fuel costs take up a large chunk of our RVing budget. So how do we improve our RV MPG?

The 5 tips I am going to share with you can apply to all RVs. This is because all RVs have an engine and tires. So you may need to improve your motorhome gas mileage or your travel trailer or fifth wheel gas mileage. It doesn’t matter, because these RV tips apply to them all. Now let’s get started!

Better RV Gas Mileage With Proper Tire Pressure

Maintaining the right RV tire pressure will have a big impact on your RV gas mileage. If your tire air pressure is low, the rolling resistance is greater. This means that it will take more energy to move your RV down the road. That means more fuel will be used to get you where you want to go.

Of course, you don’t want to over-inflate your tires either. This makes for an extremely harsh ride and can cause safety issues as well. So find the manufacturer’s recommended tire pressure for your RV and maintain that pressure in your tires. Usually there is sticker in your RV that will list the correct RV tire pressure for your rig.

If you use a tow vehicle for a towable RV, make sure that you maintain the correct air pressure in its tires too. If you want the best RV gas mileage possible, you will be checking and maintaining your tire air pressure regularly.

Keep Your RV Weight Down

It’s a real adjustment to move from a sticks and bricks home to an RV. And one of the things that a new RVer has to learn is how to manage their RV weight. This is because in our former home, weight was not an issue. So we don’t tend to think about it much when we first start RVing.

But RV weight issues impact a lot of things. There are weight limits for every RV out there. And the closer we come to the limit for our rig, the more our RV fuel economy will drop. Of course, keeping our weight low is easier said than done. But the less weight we are hauling, the better our RV gas mileage will be.

Lower RV Highway Speed = Better RV Gas Mileage

Everyone knows that the faster you drive a vehicle on the highway, the lower your gas mileage will be. But it’s surprising to see how many people ignore that principle when they drive an RV. I often see rigs of all sizes exceeding the speed limit on the highway. And sometimes, they exceed it by a lot.

Generally speaking, if you want the best RV gas mileage, you should keep your speed around 60 – 65 mph on the highway. For every 5 MPH above that limit, your RV fuel economy will drop significantly. Not to mention that it is also inherently dangerous for most RVs to be going at that speed.

RV Engine Maintenance

If you have an RV on the road, somewhere there is an engine that is pulling it. It could be either gas or diesel, but all engines need regular maintenance. If the proper maintenance is not followed, many things can go wrong. But one thing that will most likely suffer for sure is RV gas mileage.

So keep your engine in good repair and maintain it according to the manufacturer’s specifications. This means that you have to be organized and plan ahead for RV engine maintenance. But if you do, it will pay you back in the long run.

Use Synthetic Oil In your RV’s engine

This actually could be part of the last tip I mentioned above. But it is so important that I am mentioning it separately. This is because the best synthetic engine oils on the market can do a lot of good for your RV engine. Once again, it doesn’t matter whether the engine is part of your RV or not. It could be an engine in your tow vehicle.

But generally speaking, if you want the best engine lubrication and therefore the best RV gas mileage, you should use a synthetic motor oil. It will cost you a little more when you change the RV engine oil. But it’s the best protection for your RV engine that you can get. And don’t forget to change the engine air filter regularly too for good RV fuel economy.

If you use all 5 of these tips, you are well on your way toward getting the best RV MPG possible. Have safe and happy travels my friends!
