DW and I have bought a 2013 Edge and a 2014 F350 DRW. I've read in manuals that both vehicles recommend synthetic. I've used Mobile 1 and Delvac 1 for years. It really paid off in large farm tractors that ran a lot of hours. I've always used oil testing, and could come close to double hours over conventional oil. Another thing I noticed was a lot of hours without needing engine overhaul. Matter of fact, I never had to overhaul an engine after using synthetic. I know it works, just do to many hours of use.
