  • Fuel-up reminder that sticks — a bold octane warning so you (and anyone who borrows the keys) never fill up with the wrong pump.

  • Sold as a pair — put one at the fuel door and keep a spare, or split them between two cars.
  • Compact ~1.67" size — small enough for the fuel door, cluster, or dash without shouting.

  • Premium USA-made vinyl — weather-resistant and built to survive fuel-door abuse.

Minimum Octane Rating Warning Sticker

A small reminder that saves a big headache — keep the wrong fuel out of your tuned build.

Never Fill Up Wrong Again

Tuned your car for premium and worried a valet, a spouse, or a distracted you might grab the cheap pump? This little warning sticker is a constant, in-your-face reminder to run the octane your engine actually wants. Slap one on the fuel door and the decision is made before your hand ever hits the nozzle.

It's a customer-requested favorite — simple, cheeky, and genuinely useful for anyone running a tune that depends on the right fuel.

⚙️ Installation — Wet or Dry, About a Minute

Clean the surface first. Dry install works great, or go wet with about a cup of water and a small drop of dish soap (or StickerFab Application Fluid) to reposition before you squeegee it down. No heat gun needed.
