Been a member for about a year and a half. These are what I consider to be the best oils in each respective viscosity.
Synthetic Xw-20 Mobil 1
Dino Xw-20 Motorcraft
Synthetic 0w-30 German Castrol
Synthetic 5w-30 Amsoil ASL
Dino 5w-30 Motorcraft/Pennzoil
Synthetic 10w-30 Mobil 1 Amsoil
Dino 10w-30 Chevron Supreme
Synthetic 5w-40 Redline
Dino 5w-40 Shell
Synthetic 0w-40 Mobil 1
Synthetic Xw-50 Mobil 1
I define best by performance (NOT JUST IN AN LS1 ENGINE
), cost, availability and consistancy. There are other very good oils I didn't list that some would but that is what makes it my opinion.
