Whenever I change brands I go through several cycles of a cleaning product then switch to a different oil. This strips the old and rebuilds the new. **Q: Is this compatable with alcohol?** A: YES, ester based, will not separate like non ester petroleum or synthetic 2 stroke oils in Ethanol.Very good with E85 fuel in a 2 stroke 66cc "china girl" motorized bike engine.Little or no smell compared to gas & typical 2 stroke mix.Jet richer by 30% from #70 to 64 if you get dieseling, (Dieseling is bad too lean, too hot) and replace fuel line with automotive grade and carb bowl o-ring with Nitrile (Buna-N) or Viton® (FKM) elastomer O-Rings or gasket and RTV instead of stock o-ring. E85 will lower mileage by some but act as higher octane too allowing for better high compression performance and a cleaner engine too.Off the Redline website: Contain ester base oils with the highest film strength and affinity for hot metalIncreased power and excellent scuff protectionProvides the lubricating qualities of castors, but with exceptional cleanlinessLow carbon residue dramatically reduces plug fouling and smokeCompatible with reformulated fuelsEach product works in both premix or injection systems **Q: Does this 2-stroke oil work well with ethanol fuel? 2-stroke racing motorcycle engines?** A: I've used it with racing gas I've purchased at the track I run this through my racing Go kart 2-Stroke engines (105 octane) I believe it will mix well in ethanol **Q: Well it work with other 2 storke oils that are in the bike?** A: more than likely, yes... however, to be 100% sure.. drain a little out of tank.. mix some fresh redline and mix together and see . watch for settling after some mild agitation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***T on February 26, 2026* ### ⭐⭐⭐⭐⭐ Review *by K***N on March 9, 2026* ### ⭐⭐⭐⭐⭐ Review *by D***D on April 14, 2026* --- ## 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.vn/products/16487770-40603-two-stroke-oil-racing-synthetic-16-ounce-12-pack](https://www.desertcart.vn/products/16487770-40603-two-stroke-oil-racing-synthetic-16-ounce-12-pack) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-18*
