You can also use after an oil change, but TECHRON recommends NOT to use more than twice during a new oil change. I use during the last 500 miles (whole bottle) on near empty tank & run the car until the reserve light comes on. Been using this for at least 20 years. If the car runs rough, you can pour in a bottle twice, like every 2,500 miles, or repeat the process, whichever you want to do. For best results, try & do as much highway driving after pouring in & make sure to drive at least 5-10 miles to get it up in the lines & all before turning the engine off. Since you're going to be at the gas station & pouring in before refilling the tank, this is a good time. Good Luck! **Q: What is the ratio of additive to fuel? Can it be used in nonethanol fuel?** A: 1 oz per 10 gallons. It can be used in nonethanol fuel. **Q: Can you reseal the 20 oz bottle and use the rest later?** A: You can't physically reseal the paper tab, but yes you can screw the cap back on & it will keep it sealed for later use. However, this will not guarantee the same 5 year shelf life. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Que sea un artículo que cumpla con controles de calidad. *by on Reviewed in Mexico 29 January 2026* Hola Buenos días, en lo particular este producto es de buena calidad y si creo que cumple con las necesidades. ### ⭐⭐⭐⭐⭐ ممتاز *by on Reviewed in Saudi Arabia 23 May 2026* انا فخور جدا بالمنتج اصلي ١٠٠% ### ⭐⭐⭐⭐⭐ Very fast delivery *by on Reviewed in Australia 16 May 2026* Fast delivery and all good. ## Frequently Bought Together - Chevron Techron High Mileage Fuel System Cleaner, 12 oz, Pack of 1 - Chevron Techron Concentrate Plus Fuel System Cleaner, 12 oz, Pack of 1 - Chevron Techron Fuel Injector Cleaner, 12 oz, 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.hr/products/733181172-techron-266711163-high-mileage-fuel-system-cleaner](https://www.desertcart.hr/products/733181172-techron-266711163-high-mileage-fuel-system-cleaner) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-28*
