Was browsing through my owners manual for transfer case fluid and saw the manual says GM 6094m and not Dexos approved. Not worried about it as these 5.3s aren't direct injected and before Dexos they were just fine with Dino. But 11 was supposed to be the year Dexos became mandatory. Was actually thinking about going to regular old red MaxLife before the Rotella Gas Truck went on closeout. Has this been covered a million times or was there just a run of wrong owner manuals or what?
