I think that Patman is coming fom the same perspective I am. We haven't seen an oil analysis that has looked bad using the 5w20 oils yet. For the most part, they have all looked pretty good, if not better than what 5w30 has offered in many applications.
Metroplex is unwavering in his opinion regarding 5w20 oils, and thats fine. It is interesting to note that he does use one of the thinnest 5w30's out there in Mobil One.
Oil analysis like was posted is the best way to see what the oils are doing. I too will be eager to see the Mobil 1 0w20 hit the market, and will probably do some testing in one of my F150s to see how it works!
Much of this debate is very similar to when 5w30 oils came on the market. Many folks swore they would never use the stuff, and here we are over a decade later without engines siezing everywhere due to 5w30 oils. Go figure...
