I don't disagree that it will help, but the issue is separate from the oil type as pressure used to come up normally with 20W-50.

I did a quick test before, and started the engine and took the oil cap off, counting until I saw oil come out of the cam rail squirter, was right on "8-mississippi".

Guess the sooner I get my turbo one going the better...
