Fully synthetic, ester based low viscosity oil, with Electrosyntec Technology, designed to cut oil drag yet maintain a tough low-wear film on highly stressed components. Contains advanced friction modifier chemistry to attack friction at crucial points in valve and power train systems - two sources of hidden power which give that vital edge in acceleration and full throttle output. Has produced outstanding results in dynamometer tests and in restricted racing classes, where modifications are strictly limited, power was shown to increase between 3 to 5%, which is potentially race-winning!
