Save $1 Per Gallon Every Wednesday With OnePay — Up to 50 Gallons

If you fill up the tank more than once a week, this one’s worth circling on your calendar. OnePay is offering $1 cashback per gallon of gas every Wednesday through September 15, 2026 — with a cap of 50 gallons per redemption and up to two redemptions per day.

That’s a real, recurring discount that runs all summer long and into fall — not a one-time promo you’ll forget about by next week.

What Makes This Deal Stand Out

Most gas cashback offers are capped at a few bucks or tied to a single station chain. OnePay’s Wednesday deal is notable for a couple of reasons:

• $1 per gallon is meaningful. Whether you’re in a truck, an SUV, or running a small business with a fleet vehicle, that adds up fast at the pump.
• 50 gallons per redemption. That’s a generous cap — enough to cover a full tank on most personal vehicles and then some.
• Two redemptions per day. Families or households with multiple drivers could potentially stack two fill-ups on the same Wednesday.
• It runs through September 15, 2026. That’s every Wednesday from now through mid-September — a full summer’s worth of savings.

Who This Is Best For

This deal was practically made for Southern families who drive longer distances to work, school, and weekend trips. If you’re doing a summer road trip to the Gulf Coast or hauling a boat trailer every few weekends, Wednesday becomes your new best friend at the gas station.

It’s also a smart pick for:

• Commuters who can time their fill-ups to Wednesday
• Parents running kids to summer camps, sports leagues, and activities
• Small business owners with vehicles that need regular fueling — especially if you can time two fill-ups in one day
• Anyone with a larger vehicle (truck, SUV, minivan) where the per-gallon savings hit harder

How to Use It

You’ll need a OnePay account to access the deal. Sign up, link your payment method, and use OnePay at the pump every Wednesday to trigger the cashback. The two-redemption-per-day structure means you can potentially claim the discount on two separate fill-ups — so if you and your spouse both drive, you could coordinate to double the value.

Just keep in mind that Wednesday is the only eligible day — filling up Tuesday night or Thursday morning won’t qualify.

Any Catches?

A couple of things to be aware of:

• Wednesday only. If your schedule doesn’t allow mid-week fill-ups, this deal loses most of its value.
• Sign-up required. You’ll need a OnePay account, which means a new app and payment setup. If you’re already juggling multiple payment apps, that’s a small friction point.
• Deal expires September 15, 2026. Mark your calendar — after that date, the Wednesday cashback ends.

Bottom Line

For value-conscious drivers — especially those with trucks, SUVs, or multiple vehicles — OnePay’s Wednesday gas cashback is one of the more straightforward recurring deals around this summer. There’s no coupon clipping, no special gas station to hunt down, and no spending minimum. Just fill up on Wednesdays.
