My 2 cents on switching back and forth between dino and syn. I had my truck into dealership to have work done and they changed oil after replacing the HPOP with fords dino oil. I went through two quarts of oil in less than 3k so I dumped it and went back to 5w-40 rotella syn and never used over 1 quart in 7500 miles since. It's had rotella in it since first change.
That makes me feel better payin big money for the syn rotella! So you change yours at 7500 miles then?
