What kind of engine oil does BMW use?
1 Answers
BMW can use 0W30, 0W40, 5W30, or 5W40 engine oil, and there isn't one that is the best. The explanation of engine oil specifications and the selection of engine oil are as follows: Explanation of engine oil specifications: Engine oil is the lubricating oil used by the engine, composed of base oil and additives. The 'W' in the engine oil specification stands for winter. The smaller the number before the 'W', the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable temperature. The larger the number after the 'W', the higher the viscosity and the higher the applicable temperature. Selection of engine oil: Naturally aspirated engines do not require high-performance engine oil, so mineral oil and semi-synthetic oil can be used, while a larger budget allows for the use of fully synthetic oil. Compared to naturally aspirated engines, turbocharged engines have a more precise structure, operate in more complex conditions, and require higher-quality engine oil with better fluidity. It is best to use fully synthetic oil.
