Either STA-BIL Storage or STA-BIL 360 Protection fuel stabilizers would be great for winter storage. Hope this helps! **Q: can octane booster substitute for hi octane gas** A: It's not a substitute, it's an additive. Personally, if you have a performance vehicle that requires high-octane gas (91, 93 octane), then I would buy that higher octane rated gas than use an octane booster. If you are racing a high-performance car, very high octane gas, 104 ~ 108, is available (for a very high price) but probably not necessary for most stock engine tunes. Best to think about your requirements than just buy an octane booster. Despite claims by many octane booster manufacturers that it 'adds HP and improves mileage', I have never seen a noticeable improvement over 91 octane pump gas which is the highest octane rated gas I can purchase locally. **Q: What is the difference between this product (10410) and the other 104+ by the same brand (10406)? Which should I buy for a high HP S-charged engine?** A: Hi. Each 104+ Formula focuses on specific needs. 104+ Octane Boost (10406) simply rises the performance of your vehicle's engine to avoid knocking and pinging. 104+ Octane Boost (10410) can be used as a lead substitute and full fuel system cleaner as well. In your case, I would recommend the latter as it is a bit of a stronger formula. Hope that helps. If there are any questions, please feel free to contact us at producttechsupport@goldeagle.com.

They need lead to lube the top end and avoid excessive wear. Ethanol gas (10%) is murder. Use this and SeaFoam (or similar) to mitigate this issue. You might get strange looks at the gas station, but who cares. ## Frequently Bought Together - 104+ Performance Max Octane Boost and Lead Substitute (10410) - K&N Performance+ Octane Booster: Boosts Octane and Improves Engine Performance, 16 Ounce Bottle Treats up to 18 Gallons, 99-2020 - Lucas Oil 10026 Octane Booster - 15 Ounce --- ## 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.co.th/products/24563680-performance-max-octane-boost-and-lead-substitute-boosts-octane-while](https://www.desertcart.co.th/products/24563680-performance-max-octane-boost-and-lead-substitute-boosts-octane-while) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-27*
