I have always thought that, "when in doubt about deciding which oil to use, buy the one with the highest listed flashpoint." The reason being, that a higher percentage of Group III, IV, and V components, in that oil will be reflected in a higher listed flashpoint. As a result, I'm guessing the percentage of the cheaper group I and II components will be low.
With that in mind, regarding 0W20 and 5W20 oils, I have been using (for those of you able to get your hands on it) Motorcraft 5W20 FULL Synthetic in my 2010 Ford Fusion Hybrid. Listed Flash point is 229C (or 444F). Kendall 5W20 Full Synthetic is supposed to be a "clone" of this oil, with the addition of titanium. Runs great in this application, especially in hot summer temperatures. I had NO oil consumption during a 5,100 OCI. Blackstone UOI resulted in just an iron result of just 3 during this interval (80,000 miles on the odometer). I have also used Havoline 0W20 (in the sump now), and Toyota 0W20. However, the Motorcraft give me the "just right" feel and is the quietest. Not scientific, but that is my conclusion as a test driver and owner. I bought my Motorcraft stash of 40 qts, a couple of years ago, when Advance AutoParts put it on clearance for $1.95 qt.
As a quick comparison, I found Pennzoil Ultra & Platinum with a Flashpoint of 224C. Other than Mobil 1 5W20 (230C), and RedLine 5W20, I know of no other 5W20 with a higher listed Flashpoint than what I am using.
*Late breaking news, I see the new Mobil 1 5W20 High Mileage oil, with a listed 244C flashpoint. That maybe a good future option for anyone who thinks like me. Am I all wrong in my thinking?
