1 Answers
BMW's engine oil temperature of 120°C at high speed is normal. BMW cars are equipped with high-temperature engines, where the normal engine oil temperature tends to be higher than the coolant temperature. Detailed information about engine oil is as follows: 1. Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the "blood" of a car. 2. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of lubricants, determining their fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Additives are an essential part of lubricants.
