10 Tenths Race Castor is an ashless SAE 20W-40 engine oil manufactured from high quality castor vegetable oil, synthetic ester, anti-corrosion additives and an advanced anti-oxidant. The synthetic base fluids are specially blended to produce SAE 30 and SAE 40 classifications. This helps to reduce or eliminate traditional problems such as lacquers and deposits. 10 Tenths Race Castor has retained all of the advantages of a castor-based product, including a naturally higher and stronger film strength, very high load carrying capacity, better wetting properties and reduced power loss due to friction.
