The reason I was asking is the fact I now work part time at a GM Dealer's "Goodwrench Quick Lube" and I see them selling the dexos oil and I really wasn't familiar with it. now I kinda asked about it but never got a straight and honest answer.
Now I'm not totally stupid when it comes to oils,lubricants and automobiles. I just didn't really trust their answer.
Now personally I'm not to happy with the way the place is run..as far as pushing the 3/3,000 oil change interval. to me its all about the $$$$. now there is a lot more things i can say about that but ill leave it alone...
