My take is probably...yes...and I don't think that's particularly facetious or sarcastic.
If the "future engine hardware" is designed for 0W-8 or 0W-16, there should be no problems with people in the know. My beef and the beef of others here is when an engine that was using 5W30 for several years with no issue is suddenly spec'd for 5W20 with no mods or changes to the engine. The only change was the model year, and then in that model year no other choices regarding oil grade were given. Then in other parts of the world there were no changes to oil grade for the same engine. That sparked a lot of the controversy here with several members. Now if that engine was redesigned and modifications were made to warrant the thinner oil so be it. No changes is what got a lot of people thinking and posting about it here and on other sites as strictly CAFE related. Now some of those same engines got the green light again to use 5W30, several years later.
