Can someone actually explain Dexos oil to me?
Maybe I'm just dumb (well..I know i am) but I'm just not understanding dexos oil. I get it's like a high performance oil or whatever for 2011+ GM's. But why is what seems like a GM specific oil is manufactured for all cars if it's specific to GM?
I was in the store the other day getting oil and stuff for my 01 CRV and everything from Mobil 1 to Pennzoil was dexos oil. There was only 1 or 2 bottles of Mobil that wasn't dexos. Guy behind the parts counter couldnt really explain it to me.
Dumb it down for me!
