If you’re watching gas prices closely, you’re not alone. Between daily commutes and weekend getaways, fuel costs add up fast. The good news? Cashback apps make it easier than ever to keep a little extra cash in your pocket at the pump. Whether you’re new to rewards or looking to stack savings, here’s a practical comparison of the top fuel cashback apps—so you can spend less every time you fill up.

Fluz: Instant Cashback, Zero Waiting

Let’s start with Fluz. Fluz stands out for its instant cashback model. Instead of uploading receipts or waiting days for points to clear, you simply buy a digital gift card through the app before paying at the pump. Popular gas stations like Speedway, Chevron, and Texaco are all on Fluz, making it an easy win.

Fluz is ideal for drivers who want immediate savings. For example, if you buy a $50 gift card for Speedway, you could earn cashback on Speedway right away—often up to 3-4%, depending on current offers. Plus, there’s no cap on how often you can use it, and you can stack Fluz with station loyalty programs for even more rewards.

Upside: Easy App, But Requires Uploading Receipts

Upside, formerly known as GetUpside, is another popular choice for drivers. You can save money on gas by claiming offers in the app before you fill up. Afterward, you upload your receipt or link a credit card for automatic tracking.

Upside’s offers can be higher than Fluz for select locations, sometimes reaching 25 cents per gallon. However, offers are not available at every station, and cashback isn’t instant. Funds need to accumulate before you cash out, which may not be ideal if you prefer immediate savings.

GasBuddy: Great for Price Tracking, Less So for Cashback

GasBuddy started as a gas price comparison tool, but it’s expanded to include GasBack rewards through linked debit cards. GasBuddy is handy if you want to see the cheapest gas nearby, but its cashback rewards tend to be lower than both Fluz and Upside.

If your priority is real-time fuel pricing with modest rewards, GasBuddy offers value. However, for drivers seeking faster, higher cashback, Fluz often pulls ahead thanks to its digital gift card flexibility.

Shell Fuel Rewards: Great for Shell Loyalists

For those loyal to Shell stations, the Shell Fuel Rewards program is worth exploring. By linking your account and using participating debit or credit cards, you earn fuel discounts rather than cashback.

Shell Fuel Rewards shines for drivers who prefer cents-off-per-gallon savings at Shell stations. However, its limited brand focus makes it less versatile than apps like Fluz, which covers multiple fuel merchants nationwide.

Which App Should You Choose?

The answer depends on your driving habits and how quickly you want your savings. If you love instant gratification, Fluz is the best option. With no need to upload receipts and the flexibility to use your digital gift cards anytime, you’re looking at effortless savings on every tank. If you don’t mind a bit of a wait and enjoy stacking offers at specific stations, Upside provides great value, too.

For maximum efficiency, consider using multiple apps. For instance, earn cashback on Chevron with Fluz, and use Upside offers when they align. Smart stacking means more money back on every mile.

Before your next fill-up, make sure to download the Fluz app and keep your gas station rewards accounts linked. With the right strategy, you can turn every stop at the pump into an opportunity to save.
