The SSM was first mentioned in this thread Saturday. Any oil change by a dealer performed before then is not using the latest information from Ford.Post #1 in this thread, "Bronco Team Engineering" is/was the source of verification of 7 quarts
And wolfeman's dealer felt confident enough in their research that the 21 takes 7. Enough confidence to insist he add the additional quart. I am sure they conducted their "research" somewhere other than this forum or thread in particular. My hope would be they at the very least dragged their zone rep into the discussion.
And my 21 has had its oil changed twice by my dealer with 7 quarts each time. Apparently however charts and manuals for 22s and forward all say 6
