What is the normal oil temperature?

[DiMia]

An oil temperature of 100 degrees is normal. The operating temperature of engine oil is generally between 70 and 90 degrees. During aggressive driving, the engine temperature may rise slightly under high load conditions, reaching around 100 to 110 degrees. If the oil temperature remains above 120 degrees for an extended period, it is necessary to conduct a timely inspection, as it may cause varying degrees of damage. The effects of excessively high oil temperature include: 1. Affecting the viscosity of the oil, which not only leads to severe wear of some engine components but may also cause cylinder scoring or bearing seizure in severe cases; 2. Causing the fuel injected into the cylinder to ignite prematurely, resulting in insufficient compression and reduced power.
