Technician A says that a full-flow oil filter will bypass some of the oil under cold running conditions. Technician B says that a full-flow oil filter can bypass some of the oil during high-speed operation. Who is right?

Question

Quizplus · Accepted Answer

Both technicians are correct. A full-flow oil filter can bypass some oil under cold running conditions because the oil is too thick to pass through the small filter media. It can also bypass oil during high-speed operation if the oil pressure is too high and the filter is unable to handle the volume of oil flow.
