Gas rewards programs are the highest-leverage tool most drivers never fully use. The right combination of loyalty apps and grocery programs can save 30–80 cents per gallon — and most are completely free to join.
This guide ranks the top programs across three categories — gas station loyalty programs, grocery fuel rewards, and warehouse club savings — and shows you exactly how to stack them for maximum savings.
Category 1: Gas Station Loyalty Programs
Top Gas Station Loyalty Programs by Value
1. Shell Fuel Rewards (Best for Brand Loyalty)
Free program at all Shell stations. Base discount of 3¢/gal; Gold Status (6 fill-ups/month) bumps this to 5¢/gal. Stackable with Shell credit card offers and partner promotions. Download the Shell app to activate automatically.
2. BP Rewards (Best Flexibility)
Earn 1 point per gallon + bonus points for in-store purchases. 100 points = $1 off a future transaction (not per-gallon, so value varies). BP and Amoco stations are both included. The BP app also shows local prices.
3. ExxonMobil Rewards+ (Best Reach)
3¢/gal base on every purchase at Exxon and Mobil. Additional reward certificates earned through in-store spending. ExxonMobil has the largest US station count of any major brand (~12,000 locations).
4. Circle K Inner Circle (Best Promotional Deals)
Rotating offers that frequently include 20–40¢/gal discounts for enrolled members. Less consistent than Shell or ExxonMobil but excellent during promotional periods. Free enrollment; app required.
5. Sunoco Rewards (Simplest Program)
Flat 3¢/gal on every transaction with no points tracking needed. Periodic bonus offers of 10–20¢/gal for enrolled members. Best for drivers who want a simple, no-fuss program.
Category 2: Grocery Store Fuel Programs
Grocery fuel programs reward your everyday grocery spending with per-gallon discounts at affiliated gas stations. For families who already spend $500–$1,000/month on groceries, these programs can deliver $50–$100/month in fuel savings with zero additional spending.
Grocery Fuel Program Values Compared
Kroger Fuel Points (Best National Program)
Earn 1 point per $1 spent on groceries. Every 100 points = 10¢ off per gallon (up to 35 gallons). During 4x promotions (common on select items), earn 400 points per $100 spent. A $250 weekly grocery bill with 4x items can earn 100+ points in a single week. Points expire at month-end. Works at Kroger, Fred Meyer, Fry's, King Soopers, Ralphs, and participating Shell stations.
Albertsons/Safeway Just for U (Best West Coast)
Earn 1 fuel point per $1 spent; 100 points = 10¢/gal. Similar to Kroger but tied to Albertsons, Safeway, Vons, Pavilions, and affiliated chains. Strong in California, Pacific Northwest, Mountain West.
Giant/Stop & Shop Gas Rewards (Best Northeast)
Earn 1 point per $1 on groceries; can accumulate up to $1.50/gal off on large grocery purchases. Highest potential savings ceiling of any grocery program. Redeemable at affiliated Shell stations in Northeast states.
HEB Fuel Savings (Best Texas)
HEB's program is exclusive to Texas but delivers strong savings for loyal HEB shoppers. Points expire 30 days after earning — use them quickly.
Category 3: Warehouse Club Gas
Warehouse clubs maintain gas stations as a membership benefit, typically pricing fuel 10–30 cents below the surrounding market. This is the most consistent savings category — the discount is built in, not promotional.
- Costco ($65/year membership) — consistently the cheapest station in most markets. Best value for drivers who fill up 2+ times per week. Requires Visa credit card to pay at the pump.
- Sam's Club ($50/year membership) — typically 10–25¢ below market; slightly fewer locations than Costco but Walmart's geographic spread helps. Accept most payment methods.
- BJ's Wholesale ($55/year membership) — primarily Northeast US; 10–20¢ below market. Smaller footprint but excellent pricing where available.
Stacking Strategy: How to Combine Programs
The maximum savings come from stacking compatible programs simultaneously:
- Load your Kroger Fuel Points at a Kroger-affiliated Shell station.
- Pay with a 5% gas cashback credit card (PenFed, Citi Custom Cash, or Sam's Club Mastercard).
- Activate any active Upside or GasBuddy cash-back offer before filling up.
This three-layer stack can deliver effective savings of 40–80 cents per gallon on a good promotions week — turning a $60 fill-up into an effective $48–$54 purchase.
