Been in my 2017 Class C with a Super Duty Ford 450 for 1 1/2 years now. I have near 20,000 miles on it. Religiously change the oil every 3000 miles. As you can tell, I do some mileage. So when I first got my rig new, I asked at the dealer, I called my mechanic, and even called the local Ford dealership, and no one could give me an answer. Does this motor have 6 or 7 quarts of oil? I have changed every time and put 6 1/2 quarts to be safe. I still have not gotten an answer! Thanks for any help!
