For pre-1980 classic cars and motorcycles A conventional 20W-50 multigrade engine oil formulated with high quality mineral oils plus selected additives Ideally suited to older technology and classic car engines. Offers excellent oil consumption and a very high level of engine wear protection API: SF/CC Classic 20w/50 is particularly suited to vehicles from around 1950 to 1980 that require a mineral multi-grade oil. It should be used in vehicles fitted originally, or retro-fitted, with a modern style spin-on oil filter. It is also suitable for later classic motorcyles, wet clutches, but should not be used in bikes with roller main bearings (these require a monograde).
