Does a new car need engine oil?
1 Answers
New cars do not require additional engine oil during the break-in period. However, after the break-in period, it is necessary to replace the engine oil because the oil used during the break-in period is specifically designed for this phase to increase friction between components. The break-in period typically lasts between 3,000 to 5,000 kilometers, after which the engine oil should be changed. 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 the sealing of piston rings, and cool the engine by carrying away heat from moving parts.
