It's ready for it's first change since I purchased it a year ago Oct. 2013,(2,000 miles in a year) only to read the owner's manuel which states use synthetic oil. Not certain what dealer put in at time of purchase.
Can I use the regular oil, not synthetic and a Fram filter????????
noooooo use motorcraft or purlator filters fram is JUNK paper end caps. Motorcraft and purlator have metal end caps and are way better.
