100％ SYNTHETIC
Premium Pro oil has 2 grades; 0W-20 and 20W-60. "Engine oil setting" can be done by mixing these 2 types to obtain a specific viscosity to match the tuning level and/or use conditions. (See the Oil Mixture Viscosity Table below.) Oil viscosity can be adjusted as tuners want to reduce friction loss or to maintain sealing action with oil when clearance between parts must be wider, oil viscosity can be adjusted.
