Default Re: What engine oil?

Use a good oil.

There are varied opinions on what grade of oil and if there should be detergent in the oil and if there should be zinc additive in the oil. Some say when it was new the oil recommended by Ford was 30 Wt non-detergent so that is what you should use. Some say do not use detergent oil because it will dissolve any sludge build up in the engine and destroy the engine. Some say use an oil with zinc because it will prevent the camshaft from wearing out real fast.

I say use a good grade multi wt detergent oil. Zinc additive is not needed, detergent will not dissolve existing sludge.
