What type of engine oil is used for the Audi A4?
1 Answers
The Audi A4 uses 5W-40 engine oil. The primary functions of engine oil are to reduce friction and wear on moving parts, remove sludge (one of the functions of dispersants) and varnish (cleaners) from the engine, neutralize acids produced by fuel and lubricant oxidation (cleaners), improve piston ring sealing, and cool the engine by carrying away heat from moving parts. Taking the 2008 Audi A4 1.8T Individual Style Edition as an example, its body dimensions are 4587mm in length, 1772mm in width, and 1427mm in height, with a wheelbase of 2642mm. The body structure is a 4-door, 5-seater sedan.
