You won't typically find cards that feature gas, grocery, and dining, but there's still several cards that can provide you a solid return if you're looking to have one card that rules them all. If you don't mind picking up more than one card, there's various combinations that can help you build up your rewards at a great rate.
American Express Cards
One of the top cards for gas and supermarket purchases is the AMEX Everyday Preferred Card. It earns up to 4.5x Membership Rewards Points on supermarket purchases, up to 3x on gas station purchases, and up to 1.5x on everything else. You could run the dining through this card as non-category spend or pair it with the AMEX Green to earn 3x on your dining as well as 3x on travel and transit purchases as well.
Another great option in the Membership Rewards department is the AMEX Gold Card which earns 4x on both dining and grocery purchases. You can pair it with the Blue Business Plus if you're looking to earn 2x on gas and all other purchases.
Sam's Club & Costco Rewards
If you shop at Costco or Sam's Club, the Costco Anywhere Visa Card and Sam's Club Mastercard both earn great returns on gas and restaurant purchases. The only drawback is that you only receive your earned rewards once per year.
