CHARLOTTE, N.C.—Circle K is offering 40 cents off per gallon of fuel today between 4 p.m. and 7 p.m. local time during its second Circle K Fuel Day. At over 5,000 Circle K and Holiday Stationstores, customers can fuel up ahead of the long weekend and unofficial start of summer.

“After an overwhelming response from customers, we are thrilled to bring back Circle K Fuel Day in a bigger way,” said Louise Warner, senior vice president, global fuels, for Circle K. “With summer right around the corner, we want to thank our customers for their loyalty by providing them an opportunity to fuel their adventures and enjoy some great savings.”

During Fuel Day, customers will also have the chance to save all summer long. Most locations will hand out a limited amount of fuel discount cards valid for 10 cents off per gallon of fuel throughout the summer season.

The fuel sale will only be available at participating company-operated and select franchise-operated U.S. fueling locations.
