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.

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.
