Is it normal for a car's engine oil temperature to display 100 degrees?
1 Answers
A car's engine oil temperature displaying 100 degrees is normal. There are several reasons for a car's engine oil temperature to show 100 degrees: 1. When driving at normal speed, the cooling effect of the coolant will lower the oil temperature. During normal speed driving, the oil temperature will drop to around 80-90 degrees due to the cooling effect of the coolant. 2. When driving at low speeds, the cooling effect of the coolant decreases, causing the oil temperature to rise. At low speeds, the coolant's effectiveness is reduced, and the oil temperature will rise slightly (around 100 degrees). The functions of engine oil are as follows: 1. It lubricates the engine. 2. It provides cooling, cleaning, sealing, rust prevention, and absorbs impact loads.
