I checked my downloaded manual as well as my printed manual in the glove box. Both say 8.5 qts with filter, and my dipstick reads normal doing just that. Do other people's manuals specify differently? Honest question.
I put all oil in the oil fill port, none added to the filter.
Not to hijack, but what about 0W-30? Great flow and protection at low temps/startup and a bit more viscous when things heat up. I base that perceived best of both worlds benefit on nothing fyi. Just a random thought.
