Engine oil

The viscosity and maker approval your engine is filled with.

Buying advice

The approval code (API SP, ILSAC GF-6, VW 504 00, BMW Longlife-01) matters more than the brand. Viscosity and capacity are in the owner's manual — capacity changes with the engine, and sometimes with the model year.

Check before you buy: trims and mid-year changes can affect fit. Enter your VIN or registration at the retailer to confirm, and compare the OEM number on your old part.
