Citi and ExxonMobil recently made changes to the ExxonMobil MasterCard rewards program, upping the rebates awarded and making it more competitive with other gas rebate cards on the market. Previously, the card offered a 3% rebate at Exxon or Mobil stations and a 1% rebate on all other eligible purchases. Now, the terms are:

You earn rebates of $0.15 per gallon on eligible gasoline purchases made at Exxon and Mobil stations in the United States (“Exxon and/or Mobil Gasoline Purchases”). You earn rebates of up to 2% on other eligible purchases (“Other Purchases”) you make each year as follows: 0.5% on your total annual Other Purchases up to $999; 1.0% on your total annual Other Purchases over $999 and up to $5,999; 2.0% on your total annual Other Purchases over $5,999 and up to $10,000; and 1% on your total annual Other Purchases over $10,000.

You’ll note that 15 cents per gallon is still inferior to the other gas cards offering 5%, often on any brand of gas–at least as long as gas is above $3/gallon. The tiered 2% rebate on other purchases, however, can be worthwhile, and is maximized if you can spend exactly $10,000 annually. If you have enough discipline to spend precisely $10,000, your rebate on that amount would be 1.35%.

Rebates are automatically redeemed as a credit against future Exxon or Mobil gas purchases in increments of $10. In addition, the card offers a 0% intro APR on both purchases and balance transfers, though the balance transfer fee has no limit and is 3% with a $5 minimum. There is no annual fee.
