About

The Fuel Equipment Improver (FEI) is a highly efficient additive incorporated into engine fuel to enhance engine health and lifespan. FEI is specifically formulated to generate lower friction, resulting in smoother mechanical surfaces without leaving any film deposit. Whether a part is new or refurbished, a single application of FEI before installation is adequate for high-pressure fuel pumps or injector nozzles. FEI offers a projected payback period of less than a year.
