A premium non additive API GL1 rated SAE250 gear oil. Designed specifically for use in veteran, vintage and Edwardian gearbox, transaxles and selected spur and bevel type rear axles where an API GL1 non EP SAE250 or 600w oil is specified. It does not contain any aggressive load carrying additives that may cause corrosion damage to ferrous and non ferrous metal types used in these types of vehicles.
