Ok, long time no post. I haven't owned a GM F-body since 2009 and I ran exclusively GC. FFWD to now and the Camaro requires Dexos which I have read nothing about. I got excited at Walmart last night when I found what I thought was that infamous GC only to find it's 0/40 made in Belgium and for some reason it's not Dexos. The crazy thing is, it holds 10 quarts! I thought my recent Mustangs using 8 were crazy. I didn't even do research on the car and bought it the same day from a dealer without shopping them. I've never done that before, but I knew I wanted it and I knew they offered me a stupid a&^ deal. I'm in the car business, so I know what's up. It does have direct injection, so I assume that may have some bearing (no pun intended) on oil type. Thanks for any guidance. My first two oil changes are free from GM.
