A local engine rebuilder recommended using diesel engine oil in everything. It has more detergents in it and it keeps the insides of the engine cleaner.

My BIL ran diesel fuel in his engine for a few minutes to clean it out.

Added to the engine oil i hope?

Did that once with an old nissan patrol 3,3L
Half a liter diesel ontop off the engine oil.

Motor was really clean after about ten minutes idling.
(Removed rocker cover before and after)

I was always taught never to put detergent oil in an old engine that had never run on it, or it will distribute accumulated gunk into every oil way.

Especially if you have a sludge trap in the crank.
