Review: Phenomenal Cleaner With High PEA % - Does the job and seemed to help my engine run smoother. I also like that it has a high PEA content, which is one of the main ingredients I look for in a quality fuel system cleaner. It’s easy to use and feels more legitimate than a lot of cheaper fuel additives. The only downside is that it is a little pricey, but overall I’d still recommend it if you want a solid fuel system cleaner.

### ⭐⭐⭐⭐⭐ Phenomenal Cleaner With High PEA %
*by B***U on April 29, 2026*

### ⭐⭐⭐⭐⭐ Great performance and highly effective

### ⭐⭐⭐⭐⭐ The best FI cleaner available in a bottle.
*by G***X on April 17, 2026*

This has been the best fuel injector cleaner for me compared to all the others I’ve used. This cleaner uses Polyetheramine (PEA). PEA is a nitrogen-based detergent that is widely considered the "gold standard" in the industry because it is thermally stable. Unlike cheaper detergents (like PIB or polyisobutylene), PEA does not break down at the high temperatures found in the combustion chamber, allowing it to effectively remove carbon deposits from fuel injectors, intake valves, and the combustion chamber itself. Also, out of all the over the counter FI cleaners, Redline has the highest concentration. Red Line SI-1 generally contains between 30% and 40% PEA by weight. Chevron Techron Concentrate Plus: Typically contains 20% to 30% PEA. Gumout Regane High Mileage: Usually sits in the 10% to 25% PEA range. This product is expensive, but I wouldn’t use anything else.
