Ford F-350 Super Duty Problems

Use correct oil to prevent engine performance problems on Ford F-350 Super Duty

Problem Description and Possible Solution

Using the correct oil for this engine is critical. Improper engine oil can foam in the high pressure system and not develop enough pressure for operation. Symptoms of this can be hard starting, long cranking time before start, rough engine idle, and a lack of power. Another sign is tiny bubbles in the oil on the engine oil dipstick after the engine is shut off. The additives in the correct oil that protect against foaming can still break down, so changing the oil at the correct intervals is important.
