Liquid Performance's Ethanol Equalizer is the only fuel additive needed to fix problems related to ethanol and non-ethanol added fuels. Its full synthetic formula removes water from your fuel tank caused by ethanol phase separation, stopping corrosion and engine detonation problems. With its advanced fuel system detergent, Ethanol Equalizer maintains a clean and lubricate fuel system improving power and throttle response. Ethanol phase separation in ethanol added fuels as well as time and humidity in non-ethanol fuels lowers octane levels. Ethanol Equalizer stabilizes fuel for over 3 years as well as adds up to 4 numbers, or 40 points of octane ensuring fuel quality and guaranteeing maximum mileage and performance with every fill up.
