I was having a conversation with one of our Oz oil experts about alternative oil for my GM DI/AFM 4.3 and he recommended Mobil 1 ESP 0w-40 with the Dexos2 certification. ESP 0W-40 After some searching I realized the only Dexos2 oil available in North America is 5W-30 AC/Delco and Raloy Lubricantes, S.A. de C.V. (?) . The rest of the world gets 5W-40 and 0W-40 Dexos2 oil in various brands. What's up with that? Also GM calls Dexos2 diesel oil but the rest of the world calls it diesel or gas engine oil.
