Review: No hardened valves seats NO PROBLEM - Does what it says. Trust in the science behind it. Running this product in several engines built before the 1970s that have remained in continual operation since new. Gives you the lead substitute chemical plus an additional "stated" octane boost. We have our engine oil analyzed proactively and we are not seeing any abnormal signs of internal engine degradation. Easy to add when fueling. The goal is routine operation of your aging vehicles with a sustained heat cycle. Machines are like the human body; use it or lose it! 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. ## Features - Package Dimensions: 9.906 cms (L) x 6.096 cms (W) x 9.906 cms (H) - Product Type: Auto Accessory - Package Quantity: 1 - Country Of Origin: United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CCMMCK | | Best Sellers Rank | #69,642 in Automotive ( See Top 100 in Automotive ) #15 in Octane Boosters | | Brand | 104+ | | Customer Reviews | 4.6 4.6 out of 5 stars (139) | | Date First Available | July 7, 2004 | | Is Discontinued By Manufacturer | Yes | | Item Weight | 15.9 ounces | | Item model number | 10410 | | Manufacturer | Gold Eagle Co. | | Manufacturer Part Number | 10410 | | Model | 104+ Performance | | Product Dimensions | 9.63 x 8 x 7.81 inches | | Special Features | Acts As A Lead Substitute, Cleans Fuel Injectors and The Complete Fuel System, Maximizes Power and Improves Gas Mileage, Reduces Knocks, Pings, and Hesitation, Safe For Catalytic Converters and Oxygen Sensors | ## Images ![104+ Performance Max Octane Boost and Lead Substitute (10410) - Image 1](https://m.media-amazon.com/images/I/61EWyh9KUUL.jpg) ## 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.
