Rymax Engine Performance Booster is a new generation, ashless, boron ester based friction reducer and anti-oxidant, which adds unique features to any standard motor oil. Works extremely well in synergy with traditional friction modifiers in common engine oils. The highly polar ester borate forms a protective friction reducing layer of boron nitride under pressure and heat protecting all engine parts most susceptible to wear. The ceramic coating will stick to the surface of internal engine parts, even when the engine is off, providing immediate anti-wear protection at start-up.
