Are you looking for the best gas credit card now that we have $4 gas? Fortunately we have personal finance blogs to cut through the fluff and tell you straight which is the best card. Right now, the best gas credit card appears to be the American Express SimplyCash® card. It offers 5% cash back on gas and they credit it directly to your account. No shenanigans about requesting a check over $50, depositing a check, waiting, sometimes forgetting to request it, etc. Credit directly to your account FTW!

The only concern is that it’s a business card, which means you have to have a business right? Nope. You can apply as a sole proprietorship, use your social security number as your EIN, and you’re in luck. This is entirely legitimate and there are no tax implications of doing so.

The other cards mentioned, the Discover Open Road and the American Express Costco TrueEarnings cards are less desirable. The Discover Open Road limits your cashback to $20 a month (first $100 in purchases) and the TrueEarnings card has an annual fee unless you’re a Costco member (and is only 3% cashback, 5% for the business card version). You are better offer with the SimplyCash card.
