The effect of lubricant temperature on pressure
Thread Content
The impact of the engine lubricant temperature on pressure: What temperature do you keep for the lubricant? We maintain it at 35-40 degrees. Sometimes, when the temperature is low, the oil pressure increases. Why is that?
As the oil temperature drops, the viscosity of the lubricant increases
At low temperatures, viscosity is high, so the pressure at the oil pump outlet is high; the same is true in reverse.
Agree. 【When the temperature is low, viscosity is high, so the pressure at the oil pump outlet is high; the same holds true in reverse. 】
