What happens to engine oil when overheated?
A car’s internal heat could cause a chemical reaction in the motor oil, which in turn causes the oil’s viscosity to change, making thermal breakdown among the most damaging effects. If your vehicle’s engine warms up beyond a certain temperature threshold, the motor oil will degrade.
