Has your dealer been doing the oil changes properly? The 350H takes 4.6 Qts of oil vs 5.9 for the 350. When I took possession of my CPO, it had just gotten an oil change. I saw that it was way over the full line, probably a quart over. I tried to use my HFreight electric pump that had bailed me out on all my previous cars, but it took out a a couple of pints and stopped. It's still overfilled and I don't want to argue with a service manager that "it's fine". Wondering if anyone else has had this experience. I may have to crawl under there and try to drain off the extra quart...
