This time-limited “Fuel Day” event eases budgets back to school and it also supports military families with 10% profits to the Children of Fallen Patriots Foundation.
What is Circle K Fuel Day?
Circle K’s Inner Circle Fuel Day is a one-day offer for Inner Circle loyalty members to enjoy savings worth 40 cents off every gallon of gasoline at select gas stations. This is the fourth Fuel Day for 2025, after Memorial Day and Thanksgiving, and comes just as families head into the busy back-to-school season.

What is the reason Circle K is having Fuel Day
To provide actual savings during periods when travel and spending are up, Circle K created Fuel Day. Aside from providing some relief to families feeling the crunch of a budget:

- Avoid bring-over transaction: Knowing that Fuel Day discount can be redeemed only once by Inner Circle account with the maximum of 35 gallons.
- Use more rewards: In most of the states, the 40-cent Fuel Day discount can usually be doubled with your per-gallon savings as an Inner Circle member or Circle K gift card or reloadable cash card.
- Confirm restrictions: Wisconsin regulations limit fuel discounts to no more than $4.50 per fuelling event, with a purchase of at least three gallons.
Beyond Fuel Day: Everyday Inner Circle benefits
Inner Circle rewards are much more than savings during special offers. While most everyday benefits command about 3 cents off per gallon (and 5 cents off when upgraded to Premium status after $500 spent at Circle K), Fuel Day supercharges that with a whopping one-day discount.
It is time for all the savings on the back side of saving through a charitable avenue. So mark your calendars for August 21. If you’re not in Inner Circle, you should enroll, and save an additional $0.40 every gallon fill-up-to-be on your back-to-school supplies and enjoy a more comfortable run for the rest of the season.
