Before you get a fuel discount card

Before diving into my top picks, it’s essential to consider a few factors when choosing a fuel discount card for your RV travels.

You want to be sure to choose a fuel discount card that:

  • Aligns with your RV’s fuel needs
  • Offers savings on a wide range of participating fuel stations
  • Provides significant discounts
  • Keeps any associated costs or fees in mind

Availability of participating fuel stations

It’s crucial to check if the fuel discount card is accepted at fuel stations along your planned route. Ensure that participating stations are conveniently located along your journey so that you can take full advantage of the discounts offered.

Type of fuel required

Some fuel discount cards cater specifically to diesel fuel while others cover both gas and diesel. Make sure to select a card that aligns with your RV’s fuel requirements.

Annual fees or membership requirements

Some cards may require an upfront fee or annual membership fee while others may be free to join. Evaluate the potential savings and benefits offered by the card to assess if the cost or fees justify the benefits you would receive.

Overall savings potential

Compare the discounts provided by different cards and assess how much money you can save over time. Keep in mind that some cards offer fixed discounts per gallon while others may provide a percentage-based discount. Consider factors such as the average price of fuel in your area and how frequently you fill up your RV to estimate your potential savings accurately.

Top 3 gas and diesel RV fuel cards and programs

Two of the following discount programs offer diesel savings while one helps you save on both gas and diesel.

1. TSD Losistics Open Roads (diesel)

TSD Logistics Open Roads s an excellent option for diesel RV owners. This fuel discount card offers significant savings at more than 1,500 participating fuel stations across the United States including Pilot Flying J, TA-Petro, and Speedway.

There are NO sign-up or membership fees, nor long-term contracts. Current members save an average of 30-40 cents per gallon off the pump price.

Instead of charging membership fees, Open Roads makes its money by keeping 10 percent of your savings per gallon. For example, if your fuel card saves you 50 cents per gallon, Open Roads keeps 5 cents and you save 45 cents.

It’s a fair trade-off that still saves you big money. If, for example, you get a 25-cent discount filling up a 100 gallon tank, you save $22.50! That pays for a good lunch!

For all Canadian clients, Open Roads requires a US Bank Account with US Currency. The account will require a US Bank Routing Number (it will be 9 digits). The account must allow for ACH withdrawals from a US based Company. If you don’t have a Social Security Number, you may use your Social Insurance Number.

2. Gasbuddy (gas and diesel)

GasBuddy is a widely recognized app that not only helps you find the best fuel prices but also offers a Free Forever fuel discount card. This free membership card provides up to 25 cents off per gallon depending on the participating station and the fuel type (gas or diesel).

The GasBuddy card can be used at over 150,000 fuel stations nationwide making it a convenient choice for RV travelers. Plus, you can earn GasBack (free gas) through shopping and dining deals.

This discount card doesn’t require a credit check but does require info to verify your identity. Plus, it links to your debit card.

We know many RVers aren’t comfortable with providing personal info and linking cards. If that’s you, don’t worry; the free GasBuddy app can save you money by itself. The app is still great for finding the cheapest fuel in the area.

Plus a nifty tool for your travel budget!

The GasBuddy website also has this really nifty tool to help make your travel budget! The Trip Cost Calculator estimates your fuel cost based on your route and vehicle information.

3. Mudflap (diesel)

The Mudflap App is designed for truckers but diesel RV owners can benefit from it, too. You can get discounted fuel rates at over 1,500 truck stops nationwide.

Their network of participating locations is relatively small compared to other discount cards. However, you’ll save about $0.40 per gallon! Plus, it’s completely free to you. Mudflap makes its money through its partnerships.

Mudflap does not require a credit card or any fees to join. Unlike Open Roads, you do not have to wait for a physical card to arrive in the mail. Instead, you simply use the app to purchase the fuel.

The app links to your credit card (not your bank account) and requires you to go to the cashier inside to authorize fueling.

Other RV fuel discount programs and memberships

There are a few other fuel discount programs and memberships worth mentioning. The following may not offer the most fuel savings but do offer additional benefits that make them worth it.

4. Pilot Flying J MyRewards

Pilot Flying J is a popular truck stop chain with a FREE loyalty program called myRewards. As an RV traveler, enrolling in myRewards grants you access to fuel discounts, free shower benefits, and exclusive discounts on seleted merchandise.

You save $0.10 on every gallon of gas or diesel for your RV. Plus, gain access to even more offers through their myRewards Plus App. (Military also saves 10 percent off food and drinks when verified by through the app.)

This program is an excellent choice for those who frequent Pilot Flying J locations. Their network consists of over 800 retail and fueling locations in 44 states.

5. Good Sam Club

Good Sam Club is not just an RV membership organization; it also offers fuel discounts. With the Good Sam Club membership, RVers save $0.05 cents per gallon on gas and $0.10 per gallon on diesel at Pilot Flying J.

This membership also provides other benefits like campground discounts and access to roadside assistance services. So, though the fuel savings is similar to Pilot J’s myRewards, you can get more types of savings with Good Sam.

Good Sam membership starts at $29 for 1 year which can easily pay for itself if you take advantage of all the discounts.

6. Costco

While not exclusive to RV owners, a Costco membership can be a valuable addition to your fuel savings strategy. By purchasing fuel at Costco gas stations, you can enjoy consistently low prices which are often significantly cheaper than regular gas stations.

On average, you can expect gas prices that are 20-30 cents cheaper than nearby gas stations. Most Costco locations only have gas but some select locations sell diesel.

Like Good Sam, Costco offers lots of opportunities to save on more than just fuel. As you know, you can save on food, clothes, tires, and various products. But you can also save a lot on theme park tickets, cruises, discounted restaurant gift cards, and more.

Tips on How to Get Better Fuel Mileage in Your RV

Here’s advice on how to get better fuel mileage in your RV

With fuel prices skyrocketing across the country, you may be concerned about your next big road trip. And rightly so! You may not know this but the average RV is driven about 5,000 miles each year. For us, it’s somewhat more.

Some rigs get only 5-7 miles per gallon (mpg) while other more fuel-efficient models can get up to 18-25 mpg. This is important because gas mileage efficiency can save you thousands of dollars over the lifetime of your RV (and maybe even on one long, road trip).  

How you drive and take care of your RV can have a big effect on how much fuel you use.

The cost of RV driving

Most RVs average about 10 mpg. If you have not calculated your RV’s mpg or have an upcoming trip that you would like to prepare for, you may find this helpful:

Check your owner’s manual to see what the manufacturer says your mpg is. 

Google the average cost of fuel in the area you are traveling. This matters because the fuel price is much higher in California and Washington than it is in Texas and Louisiana

Map out your entire route in miles.

Divide the total number of miles by the mpg of your RV. Then multiply that number by the average cost of gas in the region you’ll be traveling in.

Getting better fuel mileage in your RV

RVs are perfect for road trips but they can consume a lot of fuel. Fortunately, there are steps you can take to improve your RV’s fuel efficiency. Here are 13 tips to help you get more out of the fuel you buy.

1. RV size/weight

One of the most obvious ways to increase your fuel efficiency is by purchasing a smaller RV. If you want a better mpg, you need to go smaller and lighter.

On average, class A motorhomes will get about 6-13 mpg. Class B motorhomes will average approximately 18-20 mpg. And Class C rigs usually average 10-15 mpg. To learn more, read Meet the RVs: Find the Right RV Class for Your Travel Style.

If you already own an RV and don’t want to purchase a different one, there are other things you can do. We’ll cover those other options in just a bit.

2. Consider diesel

You can choose to a diesel engine in any class and see some fuel savings. Overall, diesel provides about a 30 percent increase in fuel efficiency compared to regular gasoline engines. 

Diesel engines do require considerably more oil than gas engines, though. So there’s an added expense there. But you only need to change the oil once a year or every 15,000 miles compared to every 6 months with a gas engine. Also, the initial cost of a diesel motorhome will be higher than a comparable gas engine.

3. Trip planning

Plan ahead. Trip routes matter! You get better fuel mileage on highways than on winding backroads. If you’re trying to maximize fuel efficiency, select a route that avoids gusty winds and intersections as much as possible. Google Maps has a setting for this. It’ll show a little leaf next to the most fuel-efficient route when presenting your route options.

Many other apps, however, try to route you to your destination in the shortest way possible. But sometimes, these routes can have increased stops or mountainous roads. Some routes may be slightly longer but can save you fuel because you can drive smoothly and at a steady speed. 

Do the little research before you go!

4. RV maintenance 

Be sure to stay current on your RV maintenance. A dirty air filter can decrease your fuel efficiency by about 10 percent. A faulty oxygen sensor can be even more damaging by cutting your gas mileage by up to 40 percent. 

By staying on top of your rig’s regular maintenance, you can avoid any hidden gas zappers. 

I have a few helpful articles on maintenance:

5. Towing weight

The heavier weight of your RV, items that you pack, and any tow vehicles can affect your mileage. Avoid carrying items you don’t need. In other words, the heavier your rig, the less mileage you can get. This also goes for vehicles (toads) that you may be towing.

6. Maintain the correct tire pressure

Maintaining your RV’s tire pressure can profoundly affect your fuel mileage. Properly inflated tires can boost your RV fuel efficiency by up to 3 percent. 

There’s usually a sticker in your door frame that shows what tire pressure you should use. Or, check your user’s manual. 

Don’t fill your tires based on the psi number on your tires! That’s the maximum pressure your tires can hold, NOT the recommended pressure for your vehicle.

By the way, you should always check your tire pressure when the tires are cold, not after driving. And be sure to check the psi on EVERY travel day.

7. Check your oil

Keeping your oil at the recommended level for your vehicle helps maintain the efficiency of your engine. When your engine runs smoother, your fuel efficiency increases.

Keep your oil between the minimum and maximum marks on the oil dipstick to maintain your RV’s performance. 

8. Watch your speed

Maintaining a steady speed and keeping that speed below the maximum for the road you’re traveling on can help with your fuel mileage. Driving too fast can cause your engine to be overworked, needlessly using fuel. 

The greatest improvement comes with slowing down. The difference between 65 and 70 mph is surprisingly dramatic.

Overall, slowing down and maintaining a steady speed can prevent you from braking and repeatedly accelerating which also zaps your fuel.

9. Balance matters

RV owners can improve fuel economy by optimizing their RV’s weight distribution. Heavy items should be closer to the floor and RV owners should try to distribute their weight to balance front to rear and side to side. 

10. Don’t idle excessively

An idling engine can eat up a ton of your fuel. If you make a stop that will last more than a few minutes, you’ll want to turn off your engine. 

You also want to try and avoid hitting rush hour traffic in the cities through which you are driving. Not only will it save fuel but it will be less stressful.

Avoiding idling not only saves you money on wasted gas but over time it can also save wear and tear on your engine. 

11. Mind your air conditioner

Another tip for increasing your fuel economy is to mind your A/C. Turning off the air conditioner and changing the A/C filters can also save you money. 

Running the A/C adds strain to your engine especially when you are traveling at lower rates of speed. That strain equates to more fuel usage. In addition, replacing your A/C filters can reduce that strain on your engine and increase your fuel efficiency by up to 10 percent. 

That might not seem like much, but combined with all of these other tips, a vast gas-saving!

12. Avoid rough terrain

Avoiding rough roads can also end up saving you money in the end. That is because unnecessary braking and acceleration can sap your gas. 

Scan the roads for hazards, drive slowly, and use highways or smoother and well-maintained roads as much as possible.

13. Keep track of your fuel economy

A drop in your vehicle’s fuel economy can be a sign of engine trouble. Keep track of your fuel economy by noting the odometer reading and the number of gallons purchased each time you fill up. To calculate your fuel mileage, divide the number of miles traveled between fill-ups by the number of gallons purchased.

By following these few simple steps, you can prolong the life of your RV’s engine and save money on fuel and maintenance costs. Overall, being a smarter driver can make your RV lifestyle less expensive and more enjoyable. 

We RVers may wander far and wide but it’s true for most of us that we end up with some favorite Go-To places―places that draw us back again and again.

Arizona is one of those places for us. And we know it is for many RVers looking to get away and explore during the winter. 

That’s why I wrote these five articles:
