What kind of oil does a BMW use?
1 Answers
BMW generally uses fully synthetic oil. Because the internal structure of BMW engines is relatively complex, it requires the use of high-quality oil. The advantages of fully synthetic oil are as follows: Low evaporation loss: Synthetic oil is a pure compound with a narrow boiling point range, and its evaporation loss is much lower than that of mineral oil, which can reduce fuel consumption, decrease exhaust emissions, and extend the service life of catalytic converters. In addition, compared with traditional mineral oil, synthetic oil also has excellent chemical stability, good radiation resistance, high oil film strength, and less foam. Therefore, high-end cars generally choose synthetic oil. Excellent high-temperature and low-temperature fluidity: Synthetic oil has a higher viscosity index than mineral oil, and its viscosity changes less with temperature. At the same high-temperature viscosity, most synthetic oils have a lower pour point (or freezing point) than mineral oils. For the same oil film requirements, synthetic oil can achieve engine protection with a lower viscosity. There are many brands of fully synthetic oil. Mobil: It entered the Chinese market relatively early and is highly favored by car owners for engine protection, extended maintenance cycles, and improved performance. Shell Helix Ultra: It is added with Shell's high-performance dynamic cleaning and dispersing factor, which can clean the engine interior to the greatest extent and effectively prevent the accumulation of carbon particles, thereby preventing sludge buildup and carbon deposits.
