Supertech full synthetic 5w30 is dexos gen 2 certified. It does not list ford 946-a spec. What are your thoughts on this oil in a 6.2?
Gm says dexos is all that is required. And ford manual says just use an api sn oil.
Contact Warren directly, they will send you the spec sheet. They are always helpful. The oil meets Dexos 2 which is miles above the outdated ford spec. Here is the last file I have on it.
