Gas is a high-frequency, predictable spend category. Cards with 3-5% earn rates on fuel can return $120-$300+ per year at average household gas spend. Here are the 4 cards worth shopping for gas rewards.
5% cash back on your top eligible spend category each billing cycle (up to $500/month). If gas is your biggest category, this auto-earns 5% on gas without any manual selection. $0 AF.
5% on gas stations during the quarterly rotation when gas is a featured category (typically Q2). First-year Cashback Match doubles the 5% to effectively 10% year one. $0 AF.
4% cash back on gas, 3% on dining, 2% on groceries — a strong multi-category card with gas as the anchor earn category. $0 AF.
2% flat on everything including gas. No category confusion, no rotation tracking. Beats category cards once you exceed the gas spend cap. $0 AF.
Most gas category bonuses require the merchant to code as 'gas station' or 'service station'. Costco and Sam's Club fuel typically code as 'warehouse club' — NOT gas — and don't qualify for gas category bonuses on most cards. Exception: the Costco Anywhere Visa by Citi specifically earns 4% on Costco gas. Standalone Shell, BP, Exxon, and independent stations almost always code correctly.
Increasingly yes. Many issuers have expanded 'gas/fuel' category definitions to include EV charging stations (ChargePoint, Tesla Supercharger, Electrify America). Citi Custom Cash includes EV charging in its gas category. Verify with the specific issuer before relying on it.
Average household buys ~$200-$300/month in fuel. At 5% earn rate vs 2% baseline: $72-$108/year incremental. Higher for multi-vehicle households or high-mileage drivers. For context, EIA national average gas data is available at eia.gov. The CFPB has consumer guidance on credit card rewards at consumerfinance.gov.
