What brand of engine oil should be used for BMW M4?
1 Answers
BMW M4 uses Castrol original equipment manufacturer (OEM) engine oil. Precautions for changing engine oil: 1. Pay attention to the timing of oil changes. The interval for oil changes is generally determined by mileage and time: conventional mineral oil should be changed every 5,000 kilometers or six months; semi-synthetic oil every 7,500 kilometers; and full-synthetic oil every 10,000 kilometers. 2. Be mindful of the amount of oil added. The oil level should be slightly below the mark on the dipstick and not overfilled. Engine oil is crucial for engine operation as it serves the dual functions of lubrication and heat dissipation. Therefore, the engine must never run without oil. However, excessive oil can increase the rotational resistance of the crankshaft, reduce engine output power, and cause the excess oil to enter the combustion chamber, leading to oil burning, blue smoke emissions, and increased fuel consumption. 3. Choose the right engine oil. In terms of types, the most common engine oils on the market today are semi-synthetic and full-synthetic oils. This is because modern car engines are increasingly advanced, requiring higher-quality engine oil. Comparatively, full-synthetic oil is of higher quality.
