I just read the tail end of this so it may not relate.
Where I agree with 7777 is for a dollar more you might as well run a true grpV oil instead of guessing what's in it. I think it's a safe assumption that if any of the Mobil One products were primarily ester based they would be advertising the heck out of it instead of resorting to the proprietary line.
Mobil One is a fine oil but paying a dollar more for an ester base with most of them being VII-less with an awesome add pack seems like a no-brainer.
