I only use Valvoline and have for years and years because of the following. It's the only oil where the inside of an engine I'd seen was as clean as the day it came off the dealer's lot. No sludge or gunk in it at all. The Chevy p/u had 100,000+ miles on it and the oil was faithfully changed every 3,000 miles. If I had seen it I wouldn't have believed it.
My 79 Formula spun a bearing in the engine and I believe it was from using Rotella 15-40 diesel oil. Never again in a gas engine.
Edit:
I forgot to add that in my 66 GTO I only run Valvoline VR-1 20w-50 Racing Oil.
