Throughout the year, Circle K offers a discount up to $0.30 or $0.40 off each gallon of gas (even diesel) during a Circle K Fuel Day. The National Fuel Day event is held during a 3-hour window (4 p.m. - 7 p.m. local time) in participating locations across the U.S.

Circle K Fuel Day Pop-up events occur in specific states and can be three hours long, while others last all day. Some events require you to be an Inner Circle Rewards member to enjoy the savings (automatically discounted at the pump). Others offer the savings to all customers.

KCL predicts the next Circle K Fuel Day will happen on Dec. 5, 2024.

Circle K holds several Fuel Day events throughout the year. One type, a Fuel Day Pop-up, happens in a few states at one time. Nationwide events occur at participating locations across the U.S. The next Circle K Fuel Day will happen on Wednesday, Dec. 5, 2024.

How Circle K Fuel Day Works

Circle K announces an upcoming event a day before the event is scheduled to take place at participating locations. Here are the differences between a nationwide and a Pop-up Fuel Day.

Nationwide Fuel Day Events:

  • Gas Savings: 3-hour window, 4 p.m. - 7 p.m., (local time)

  • Discount: $0.40 off per gallon (automatically discounted at the pump)

  • Loyalty Membership: Not required

  • Gas Savings: 3-hour window, 4 p.m. - 7 p.m., (local time) or all day

  • Discount: $0.30 or $0.40 off per gallon (automatically discounted at the pump/may require you to enter your associated phone number at the pump)

  • Loyalty Membership: Some locations require you to be an Inner Circle member, while others don't.

Circle K Fuel Day Nationwide events can offer more than discounted gas.

Circle K nationwide events offer $0.40 off per gallon at participating locations across the U.S. You have a 3-hour window (4 p.m. - 7 p.m.) to get the discount. During this type of Fuel Day event, you may find other savings as well, starting at 6 a.m. Here are some deals you may find based on what we've seen in the past.

  • Circle K team members hand out fuel discount cards worth $0.10 off/gal for future purchases.

  • Drinks and food are 50% off, including dispensed drinks, coffee (hot and iced), Froster, and Polar Pop cups. Look for discounted hot foods such as Circle K sandwiches, pizza slices, and other roller foods.

  • Watch for a 50% off car wash deal on any wash (Budget, Standard, Premium, and Ultimate) that will also begin at 6 a.m. and end at 11:59 p.m. (local) at participating locations.

  • Get 50% off EV charging starting at 6 a.m. We predict the 50% off EV charging will start at 6 a.m. and run through 3:59 p.m. (local) at participating locations during the next Circle K Fuel Day nationwide event.

We anticipate savings of $0.40 per gallon, starting at 4 p.m. during the next Circle K Fuel Day. This deal will go from 4 p.m. to 7 p.m. (local).
