I find the MPG thing a bit quirky too.
You may be right about full broken in. I know that metal pieces that are mirror polished have a lot less friction between them. Colt handguns always had better finishes inside than the Smith & Wesson that I worked on. I could decrease the pull on a S&W by just polishing the mating part inside to near mirror finish. Then I could trim a bit of the rebound spring off that "returns" the trigger to the forward position after being pulled back. Combining with the polishing and the trigger work, it effectively lowered the lbs of pull that was needed to fire the weapon in double action mode. I used to do a LOT of pistol tuning for guys, and making parts near mirror was a part of it all. Now stands to reason that motor oil, being Dino (aka conventional) may have some abrasive actions in it called carbon (among others). After things got polished so bright I switched to synthetic and the oil in synthetic is different. Crude oil has various sized molecules in it and some burn off (smallest) some adhere (varnish) and the rest provide lubricity in the engine. Synthetic has near uniform size molecules and perhaps it's because of this and the fact that it's stays around with less volatilization that it creates a condition for increased gas mileage. Synthetic oil has a higher base number than most conventional oils and appears to be more "detergent" oriented. Clean engines go a long way toward long life and increased performance.
Black powder shoots a bullet out from a firearm, and so does smokeless powders. The smokeless have similar but very uniquely superior qualities over the black powder of yesterday. I think in terms that the synthetic oils, whether Amsoil, Valvoline, Mobil, Red Line, Quaker State, etc have evolved into the "oils of today".
Amsoil may have been the 1st in synthetics for automotive industry, but I find it surprising how MANY are following suit. Even the Wal-Mart brand now has a full synthetic oil.
Since Mossad has indicated that price was no concern, just wanted oil to be cleanest, I would say if I had a shop with 2ea 55 gal drums of oil. One Mobil 1 and the other Havoline (or any other conventional), and was told by the oil guy that comes around, "let me know when you are getting low and I'll bring you by some more free oil" I'd use the Mobil 1. Why not?
