Review: Excelent - You can actually sense the improvement.
Review: If you have an older car this is a must have! - I have two old cars with soft valve seats. 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.

## Questions & Answers

**Q: Which product should i use to put in to vintage automobiles? they run excellent.also:do you sell a fuel stabilizer for winter storage?**
A: If your vehicle benefits from a lead substitute or a boost in octane, then this product would be best. 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. Thanks for the question!

**Q: where is a msds for this product on your website?**
A: Hi. The Safety Data Sheet List is located at the bottom of our website where it says "SDS/Certifications". If you are unable to locate it, you can also request it at producttechsupport@goldeagle.com. Thanks for the question!
