The current average for gas is $3.78, which is 14 percent higher than at the beginning of the year. A recent study by Card Hub selected five of the best credit cards for gas purchases after studying over 1,000.

Three of the cards are generic gas cards, while the other two are specific gas station based.

The points given on this card are equal to 5 percent cash back at any station where you pay at the pump.

For those who pay at the supermarkets, it's 3 percent and an additional 1 percent on all other purchases.

There is no annual fee, but you must have a PenFed membership, which is $15 unless you qualify from military connection or where you work.

Along with the 3 percent cash back for gas and some department stores, this card gets 5 percent at supermarkets and 1 percent everywhere else.

It does have a $75 annual fee, though the $150 bonus for spending $1,000 in the first three months could cover the cost for two years.

Marathon Credit Card

The Marathon card is specifically a gas card and gives 25 cent rebate for each gallon of gas that is purchased at Marathon if the cardholder charges at least $1,000.

If the consumer spends $500 to $999.99 15 cents are rebated for each gallon and less than $500 gives 5 cents.

Like the Marathon Card, this is also a station-affiliated card. For the first 60 days after opening the account, 30 cents are rebated on Chevron and Texaco gas.

Afterward, 20 cents a gallon is given when $1,000 is spent and 10 cents for $300 to $1,000. Up to $300 in discounts can be earned and redeemed each calendar year.
