for 20 yrs, you had a very few oil specs. 5W30 for most everything, 15W40 for diesels, and 5W30 Mobil 1 for Corvettes, Northstars and a few Turbo/Supercharged engines.
Then they added 5W30 DEXOS1....and 5W20 DEXOS1 for a few of the 2013s...and the upcoming new trucks will require 0W20 DEXOS1 it was annouced today....
We're about to open a new store. I had planned on going with a 500 gal tank of 5W30 Dexos, and 250 Gal tank of original 5W30, and a 250 gal of of Dextron6 - now I'm uncertain WHAT to do....why can't GM get it head together on Oil Specs?:mad:
