I know a guy who works in an industrial field and works with pumps and such. He uses a straight 50 weight in his truck. Down here in the south I guess you could get away with it, but he's an older gentlemen and I'm sure he was around before they came out with multi weight oils. He tells me a 30 weight is about as thin as you ever want to go. Opinions? I didn't have time to go into detail about it. Opinions? I believe the last time I talked to him about this is he likes that the thicker oil won't run off the parts as easily after shutdown as a thinner oil would.
Believe it or not I read an article about a guy who did a test like this about cold start noise problems and he had lots of noise with thinner oils 5w20 vs a 20w50. He claimed the same thing. The thin oil ran off the parts when the engine was hot from driving, then made noise waiting for oil to get back onto the internal parts in the morning on a cold start.
