What is the oil model for BMW?
1 Answers
For BMW 1 Series, 2 Series, 3 Series, X1 and other models, the official recommendation is SAE5W-30 and higher-grade SAE0W-40. The BMW 5 Series generally uses the oil model specification of 5W30. Oil SAE5W-30: SAE-5W-30 is a grade of all-season oil. 5W can withstand external low temperatures of -30°C, and the following 30 means it can withstand a maximum temperature of +30°C (summer temperature). Oil SAE0W-40: SAE5W-40 refers to the original oil, where 5W represents winter oil. Oil 5W30: Suitable for Japanese and Korean cars, as the engines of these two series are more precise with smaller gaps. If only considering the viscosity grade, 5W30 is suitable for colder regions and winter. Methods for selecting oil: If you value the longevity of the oil, you can use Mobil lubricants; if you care about the cleaning ability of the oil for the engine, it is recommended to choose Shell oil; if you need oil with strong oil film elasticity, you can choose Castrol. Precautions for selecting oil: Choose oil with the appropriate viscosity, and pay attention to the amount of oil added, which should not be too much or too little. Too much oil can easily increase the engine load and affect power; driving for too long can damage the engine exhaust system, increase carbon deposits, and too much oil can also create the illusion of burning oil. Too little oil will affect the overall lubrication effect of the engine, causing many components that rely on crankshaft splash lubrication to wear out more severely or even be damaged.
