DDifficulty 3/5

Which oil temperature can contribute to low lubrication pressure by reducing its viscosity?

Correct answer

Very hot.

A very high temperature can make oil more fluid and contribute to lower pressure. However, a low gauge reading alone does not prove that the oil is very hot: it can also involve oil level, the oil used or a fault. If a pressure warning appears, stop safely and follow the manufacturer’s instructions; do not keep driving on the assumption that temperature alone explains it.
