Depending on how often he drives the car and fills the gas tank, he uses 1 bottle with each fill up. I hope this answers some of your question. **Q: does this work on a 2 stroke?** A: Does your 2 stroke recommend a higher octane - 89+ and you can't get the fuel? if so, use it **Q: Is this safe for use with catalytic converters?** A: I am using it in a 66 Mustang and a 73 Z28 neither have converters, so not sure **Q: Will this stuff boost 93 octane to 95?** A: Yes, I think it is a gain of just under 2.5 octane numbers when added to 12 or 14 gallons. ## Frequently Bought Together - STP Octane Booster for Gasoline Fuel Additive, 5.25 oz, Fuel Additive That Raises Octane Levels and Cleans the Fuel Intake System to Restore Lost Power and Acceleration, Help Improve MPG - STP Ultra 5 In 1 Fuel System Cleaner and Stabilizer, Deep Cleans Fuel System and Fights Engine Friction, 12 FlOz - STP Complete Fuel System Cleaner, Fuel Cleaner Deep Cleans Entire Fuel System, 5.25 Oz, Multicoloured, 1 Count (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/253335130-stp-octane-booster-restore-horsepower-boosts-155-ml](https://www.desertcart.tn/products/253335130-stp-octane-booster-restore-horsepower-boosts-155-ml) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-30*
