These days fuel prices are climbing even faster than the mercury in a thermometer. With oil companies posting record profits, the government unwilling or unable to rein them in, and summer travel demands for fuel, the prices at the pump will only continue to climb. As RVers, we only have two choices, pay it or park it. We have no intention of getting off the road, but with a little effort and planning on our part, hopefully we can lessen the impact of today’s outrageous fuel prices to some extent.

All men are not created equal, nor are all fuel prices. RVers have a few tools at their disposal to help save money by filling our tanks at the lowest available price. Several internet websites list the lowest gasoline prices in an area, including www.gasbuddy.com and www.gaspricewatch.com. Diesel fuel prices at major truck stops are listed at www.dieselboss.com. Flying J truck stops update both their gasoline and diesel prices daily on their website at www.flyingj.com. When starting out on a trip, RVers can check fuel prices in their current location and along their route. Many times fuel prices will differ by fifteen to twenty cents a gallon from one state to the next. By checking before you leave, you can avoid overpaying for fuel and then finding it at a reduced price a few miles down the road.

Some RV clubs and other groups provide their members with discount programs that can lower the price at the fuel pump. Good Sam Club members can take advantage of gas and diesel discounts at Love’s Travel Stops (www.loves.com). Love’s offers Good Sam members a two cent per gallon discount on gasoline and a one cent per gallon savings on diesel fuel.

The RVers’ best friend in terms of fuel stations is the Flying J truck stop chain (www.flyingj.com). RVers can obtain a free RV Real Value card from Flying J good for one cent a gallon off on gasoline and diesel fuel, and five cents a gallon off on propane. Cardholders are also entitled to other discounts and promotions. In our experience, Flying J has almost always offered the lowest fuel prices in an area. Most Flying J locations also allow RVers to park overnight if they need a safe place to get off the road and don’t want to go into a campground just to get a few hours sleep.

Discount warehouse stores such as Costco and Sam’s Club usually have lower fuel prices overall and membership can result in savings on fuel purchases. Often we have found fuel prices to be several cents a gallon cheaper a couple of blocks away from the interstate, compared to stations just off the exit.

Some credit cards offer rebates or discounts on fuel purchases. Check with your credit card company to see what they may offer.

Besides purchasing fuel wisely, properly maintaining your vehicles can save you money when you pull up to the fuel pump.

If you have a gasoline engine, keep it tuned up for maximum efficiency and the best fuel economy. Switching to iridium or platinum-tip spark plugs can help maintain your engine’s peak performance for far longer than standard spark plugs, even under strenuous driving conditions such as pulling heavy trailers and climbing steep grades. Though they cost more than standard spark plugs, the premium models last much longer.

Replace air filters and fuel filters as provided by your vehicle manufacturer’s maintenance schedule. An engine that breathes better uses much less fuel.

In both gasoline and diesel engines, synthetic lubricants help reduce friction, wear, and fuel consumption and extend your engine’s life. Even if you currently use conventional motor oil, switching to synthetic oil can be done at any time. Be sure to follow your manufacturer’s recommendations for oil grade, viscosity and oil change intervals to protect your warranty. Synthetic automatic transmission fluid and other lubricants are also available and provide improved performance.

For motorhome drivers, it is better to use your vehicle’s dash air conditioner when on the road, instead of operating the rooftop air conditioning units off of your generator. Your motorhome’s engine is running anyway, so why have that genset burning more fuel at the same time? Some motorhome drivers hang a clear plastic sheet or drop cloth, which can be purchased inexpensively at any discount store, behind the driver’s compartment to keep the cold air up front while on the road, instead of trying to cool the entire coach.

Many drivers lose money and fuel mileage where the rubber meets the road. Under-inflated tires create more drag, forcing your engine to work harder to move your vehicle. It is a simple fact that a circle rolls easier and smoother than a square. Properly inflated tires also give a better ride, carry more weight, and last longer. Purchase a quality air gauge at a truck stop and check your tire pressure before each trip.

Radial-ply tires create less rolling resistance than bias-ply tires. Be aware that if your vehicle has bias-ply tires, your current wheels may not work with radial tires. Tires with highway tread patterns also contribute to better fuel economy, compared to mud and snow tires with deeper lug patterns.

The best thing you can do to conserve fuel is to drive slower. Fuel mileage drops drastically the faster you drive. Driving 55 miles per hour instead of 65 can save as much as 20 percent of your fuel. Slow down and enjoy the view and the fuel economy!

When driving in mountain country, know your vehicle’s personality traits. Our MCI bus has a four speed Allison automatic transmission. On a steep climb, the transmission shifts itself from fourth to third gear at about 45 miles per hour. However, by then the engine is lugging and we lose a lot of momentum. A glance at my tailpipe shows black smoke coming out. That black smoke is unburned fuel. I can manually shift the engine down to third at 50 miles per hour, which keeps our speed up and saves fuel.

If your vehicle is equipped with cruise control, using it will result in better fuel economy. Be aware that in certain driving conditions, such as in rain or snow, or in mountain country, for safety, cruise control should not be used.  

While tailwinds seldom seem to exist for RVers, the rare occasions we do get so blessed contribute to fuel savings. Of course, the other side of that coin is that a headwind (and we all know how frequent those seem to be) will greatly reduce fuel economy. Slow down when you encounter headwinds. You’ll enjoy a safer, more comfortable drive and reduce the adverse effects of the wind on your mileage.

Rooftop storage pods create drag that reduces fuel mileage. Evaluate whether the advantages of that rooftop storage are worth the adverse impact on your mileage. Drivers of pickup trucks and SUVs that tow trailers can benefit by a roof mounted wind deflector.

Towing a dinghy always impacts fuel mileage. For short trips, leaving your dinghy behind can be advantageous. Consider using bicycles or a scooter for local transportation when possible.

We can’t control fuel prices, but we can drive smarter and use less, lowering the impact of skyrocketing prices on our travels and depriving the fuel pump bandits of at least some of their high profits at our expense.
