Rymax Engine Performance Booster is a Boron Ester based friction reducer. It adds unique features to your motor oil and works extremely well with all common engine oils. The highly polar Ester Borate forms a protective friction-reducing layer of Boron Nitride under pressure and protects all engine parts. This additive not only boosts the engine performance but also keeps the oil performing optimally for a very long period of time. It can be used in gasoline, diesel and LPG engines with and without turbochargers and is also suitable for our Apollo / Motrax R engine oil, as it is ashless.
