As a Mazda Miata MX5 owner with a modest 11-gallon tank that demands premium fuel, I've become somewhat obsessive about optimizing my gas rewards.
With fuel prices continuing to fluctuate, finding ways to save at the pump has become more important than ever.
BP's Earnify rewards program offers several avenues for savings, and when combined with the right credit cards, the benefits become even more substantial.
The key is knowing which gas credit cards to pair with loyalty programs for maximum return.
BP recently rebranded their loyalty program to "Earnify" (formerly BPme Rewards). Here's what the program offers:
Amazon Prime Benefit: 5 cents off per gallon for Amazon Prime members
Mobile App Discount: Additional 5 cents off per gallon when paying through the Earnify mobile app
Points System: Earn 1 point for every $1 spent on gas
Redemption Structure: Every 800 points gets you 20 cents off per gallon for a one-time fill-up (points reset to zero after redemption)
With my Mazda Miata MX5's 11-gallon tank requiring premium fuel, let's calculate my monthly savings:
Monthly Fill-ups: 4 times
Amazon Prime + App Discount: 10¢ off per gallon on each fill-up
Monthly Savings from Discounts: 11 gallons × 10¢ × 4 fill-ups = $4.40/month
For points accumulation:
Assuming premium gas at $4.50/gallon
Monthly Spend: $4.50 × 11 gallons × 4 fill-ups = $198/month
Monthly Points Earned: 198 points
Months to Reach 800 Points: Approximately 4 months
Additional Savings Every 4 Months: 11 gallons × 20¢ = $2.20 (or about $0.55/month when averaged)
Total Monthly Savings: $4.95 (not accounting for any credit card rewards)
For comparison, let's calculate savings for a typical American driving an SUV that requires premium fuel:
Average Tank Size: 18 gallons
Monthly Fill-ups: 4 times
Amazon Prime + App Discount: 10¢ off per gallon on each fill-up
Monthly Savings from Discounts: 18 gallons × 10¢ × 4 fill-ups = $7.20/month
For points accumulation:
Monthly Spend: $4.50 × 18 gallons × 4 fill-ups = $324/month
Monthly Points Earned: 324 points
Months to Reach 800 Points: Approximately 2.5 months
Additional Savings Every 2.5 Months: 18 gallons × 20¢ = $3.60 (or about $1.44/month when averaged)
Total Monthly Savings: $8.64 (before credit card rewards)
Here's where the strategy gets interesting. By using credit cards with gas multipliers, you can dramatically increase your effective savings at BP stations.

BP's Earnify rewards program offers decent value on its own, but the real magic happens when you pair it with a rewards credit card. The combination of immediate per-gallon discounts, point accumulation for future savings, and credit card rewards creates a powerful stack that significantly reduces your effective cost of fuel.
For maximum rewards, the American Express Business Gold stands out for gas purchases with its 4X multiplier on fuel. For those without a business, the Citi Strata Premier offers excellent returns that can be transferred to travel partners.
Remember that Amazon Prime members get an automatic 5¢ off per gallon at BP. Combined with the mobile app discount and the right gas rewards credit card, you could be saving 10-15% on your premium fuel expenses.
