Question

Quizplus · Accepted Answer

Technician A is correct because sludge indeed results from the oxidation of oil, which can occur when the oil is exposed to high temperatures and oxygen, leading to thickening and the formation of sludge. Technician B is also correct because a slight buildup of sludge on the underside of the oil fill cap can be considered normal, especially in colder climates where condensation can mix with the oil, creating a sludge-like substance. This doesn't necessarily indicate a severe problem unless the buildup is excessive.
