Review: Great product - Great product Review: Corrects Ethanol treated fuel. - I use it on all my vehicles, Boots mileage and performance. Corrects the problems caused by ethanol. More Noticeable when I used it on an Older Porsche and My Audi. I have 2 Chevy Astro vans that run better with this boosting the fuel. The Gallon is the best value, but you need 2 drivers to use it up before it loses shelf life from opening. The Quart is working good for just me. Keeps injectors cleans, spark plugs run cleaner. Keeps my Honda Mower starting good, even sitting through the winter. But I store it with a full tank. ## Features - FUEL SYSTEM CLEANER: Cleanses the entire fuel system using PEA additives, including fuel injectors, lines, & fuel pumps.
