Designed specifically for vehicles over 75,000 miles, it reduces upper cylinder friction, combats ethanol and water corrosion, and prevents carbon buildup—delivering restored engine performance and improved fuel economy in just one fill-up. Safe for all engine types and OEM warranties, this 6-pack liquid formula is a must-have for maintaining peak efficiency and longevity in high-mileage vehicles. ## Description Gum out Regane High Mileage Fuel System Cleaner reduces friction in the upper cylinder to improve fuel economy, while using PEA (polyether amine) to effectively remove deposits other products can't for restored performance. Engines with over 75, 000 miles can suffer from extensive carbon deposits and excess friction. Gum out Regane High Mileage Fuel System Cleaner conditions fuel to fight ethanol and water corrosion, and the upper cylinder to reduce friction and wear. Cleans direct and indirect fuel injectors, intake valves and ports, piston tops, cylinder heads, and combustion chamber, providing restored performance and fuel economy in high mileage vehicles with one fill-up. Also prevents future carbon build-up and reduces emissions. Oxygen sensor safe and safe for use in turbocharged and supercharged vehicles. Will not void OEM/manufacturer’s . Directions: Add entire bottle to nearly empty gasoline tank, then fill tank with up to 21 gallons of gasoline. For best results, do not refill tank until near empty. Use every 3, 000 miles. Review: Did not eliminate engine knock, but did improve it on my 2014 prius v - Backstory, I should have used fuel system earlier in my car. At about 120k, the engine started knocking, especially with the AC running. I have used predominantly Sam's Club gas, 87 octane. I never used fuel system cleaner until then (I have in my other cars, but just never did in the Prius. With the gas practically empty, I put in a bottle and only put in 4-5 gallons of gas. It definitely helped with the engine knocking. I now use it regularly (everytime the engine starts knocking again every few thousand miles.) I did originally try this on an empty tank and filled it up the tank......did not stop the engine knocking. Thus now I only put in a few gallons. Did it improve mileage....NOPE. I did not see any performance increase. Review: Good fuel system cleaner - Reorder additional. Package had no leakage. Great value for the price and quantity. Seems to help with my mileage at 178k, using every 3k. ## Features - The ALL NEW CarbonClear technology combines the PEA cleaning power you have come to trust with PIBA, and a patented technology for a better clean. The combination of the 3 detergents work synergistically to provide better cleaning power (new formula) vs. just PEA alone (old formula). - Conditions upper cylinder to reduce friction and wear in high mileage vehicles - Fights ethanol and water corrosion and prevents future carbon build-up - Provides maximized performance and fuel economy in one fill-up - Will not void OEM/manufacturer's - Fit type: Universal Fit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RJ2312P | | Best Sellers Rank | #38,165 in Automotive ( See Top 100 in Automotive ) #67 in Automotive Fuel System Cleaners | | Brand | Gumout | | Brand Name | Gumout | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.6 out of 5 stars 482 Reviews | | Global Trade Identification Number | 30071948100238, 30071948101389 | | Included Components | Fuel System Cleaner (6) | | Item Form | Liquid | | Item Type Name | Gumout 510023 Regane High Mileage Fuel System Cleaner, 6 oz.

They have treat rates that are not the same which leads me to believe that this product is likely 25-30%PEA. While the 12 oz product is ~15% PEA. **Q: The pea is 10% to 24% for gumout. redline is 28% to 32% the only other that has pea is chevron techron all good but redline is best agree?** A: Per the Gumout MSDS Polyetheramine: 10 - 30% I've come to understand that this covers all products, this one and there is a larger 12 oz product. They have treat rates that are not the same which leads me to believe that this product is likely 25-30%PEA. While the 12 oz product is ~15% PEA. I can't seem to pull up a recent MSDS for Redline, but prior versions say 25-30% or <30%. So, bottom line is they are comparable on a cost per PEA basis. **Q: Will it affect smog test if i use it couple days before?** A: If you want to be safe, run all that fuel out before the test. That way you will get all the cleaning benefit. Honestly, I do not think the chemicals will change the test if that was your question. The Cat converter will burn most everything. **Q: i use octane buster in my 93 vet. can i use this with it?** A: Absolutely! ## Customer Reviews ### ⭐⭐⭐⭐ Did not eliminate engine knock, but did improve it on my 2014 prius v *by L***L on 9 February 2024* Backstory, I should have used fuel system earlier in my car.
