Circle K’s Fuel Day is BACK!! Members Save 40¢ Per Gallon on 8/13 – a solid discount for anyone filling up at CircleK. This limited‑time offer drops the price of gas by $0.40 per gallon, helping drivers stretch their budget farther.

Why this fuel deal stands out

  • Immediate cash‑back at the pump – no coupons to clip.
  • Only available to Circle K members, rewarding loyalty.
  • Works on any grade of gasoline, so you can choose premium if you prefer.

    • How to grab the deal at CircleK

    1. Download or open the Circle K mobile app.
    2. Tap the “Fuel Day” promotion on 8/13.
    3. Pay at the pump using the app‑linked payment method. The discount applies automatically.

    Savings tips & price context

    Even after the 40¢ discount, gas prices can vary by region. Compare the posted price at your local Circle K with nearby stations to ensure you’re getting the best rate. If you already have a Circle K loyalty card, the discount stacks with any other in‑store offers, so keep an eye on the app for additional promos. Consider filling up early in the day when demand is lower; some stations post slightly lower prices during off‑peak hours. Pairing the discount with a full‑tank fill maximizes the dollar amount saved.
