I want the time back that I spent reading a few pages of this thread. What total pap. No UOAs to substatiate anything, and the rest a bunch of marketing filler. "The formula hasen't changed since 1985" well then it is not as good as it could be because there have been SIGNIFICANT improvements in lubrication since that time. Do you really believe 20 year old tech is that good, and that the lubes of that time are better than they are now?

No explanation of how the oil does not oxidize or nitirate. No explanation of how the additives in the oil do not get used up or break down. No explanation of how the wear metals floating around for such a long period of time will not be abrasive. Even their own web site says that the wear metals will be higher in a UOA this length, yet on the same site they claim that oil does not get dirty!

What is the base oil used and who makes it? 20 year old PAO? This is one thing I have never seen anyone post. And getting 2-3mpg improvement by going from 5W30 to a 50wt? The car manufactures would KILL for an improvement like that, and add to the fact that it would be a serious marketing gain to say that you never have to change your oil. They would be all over it. The fact that they are not speaks volumes.
