Heavily favoring putting 50% Redline oil into the mix in my 4.3 when it comes back. Liking the Redline 0W-20 since it is a thin 30-weight - sounding perfect for my engine. I am loathe to use 10W-40 conventional.
The other half would probably be a 5W-30 conventional, high in moly. I stocked up on clearance, but that other half may end up being a quart GC 0W-30. Eventually.
I heard Group V "sticks to the metal parts inside" better on start-up, then enables engine to run silky smooth.
I even have a quart of Redline 0W-30 coming, whenever Amazon.com decides to ship it.
Thoughts and opinions?
