Admin If you drive in California, Colorado, New Mexico, Oregon, Texas, or Washington, today is the day to fill up. Circle K’s Inner Circle Fuel Day is running right now, Thursday, October 15, with 40 cents off every gallon — all day long, from 12:01 a.m. to 11:59 p.m. local time.
On a 15-gallon fill-up that is six dollars back in your pocket for doing absolutely nothing different. Every fuel grade is included, diesel too, and the discount stacks with Easy Pay if that is how you usually pay. The only requirement is Inner Circle membership — but joining is free and takes about a minute in the app.
How to get the discount
- Make sure you are registered for Circle K’s free Inner Circle program — sign up in the Circle K app, text JOIN to 25050, or join online before you fuel.
- Head to a participating Circle K in California, Colorado, New Mexico, Oregon, Texas, or Washington today, October 15.
- At the pump, enter the phone number tied to your Inner Circle account before you start fueling (or give it to the cashier inside).
- Watch the price drop 40 cents per gallon automatically. The limit is 35 gallons per transaction.
