Lets take 3 oils, the mfg is not important all oils a 20 grade for an engine spec'd for a 20 grade. Here are some of the specs, which would you use based on specs alone, and why? Most oil buffs might know the products by the specs, (PLEASE LETS NOT GET BRANDS INVOLVED, LET THEM REMAIN NAMELESS). These are 0w20 and 5W20 grade oils. I didn't label them. I made a friend on this site and we've exchanged a few PM's about this and he suggested I run this question on the board.
Lets say you were going to use one one for all seasons, temps from -10*F- 100*F.
