Why Mobil 1 oil for our Evos?

Wonder why no one has done a really extensive test on oils.
I cant remember seeing anything in mags.... or online
Okay, here's a little primer on synthetic oil.
There are two ways to make synthetic oil. The first is to use a base stock consisting of one or more synthetic lubricants such as polyalphaolefins (PAOs), esters, alkylated naphthalene (AN), etc. This is the original, "fully synthetic" method that Mobil 1 used to use.
The second method is to take petroleum-based feed stock (regular dino oil) and react it with hydrogen to break the longer hydrocarbon chains (grease-like oils and waxes) into shorter chains more suitable for lubricating. This is called hydrocracking and hydroisomerization. This is the "new" synthetic method that Castrol introduced with the reformulated Syntec, and that Mobil 1 now uses.
Traditional dino oils are produced by distilling crude oil. The resulting oil is heavily contaminated with longer- and shorter-chain hydrocarbons that hinder its lubrication performance.
The first method produces a slightly better (cleaner, more uniform) product, but costs about twice as much. Either synthetic method will produce a superior product to distillation. Whether the difference between synthetic and cracked-base stock is worth the price difference is much less certain since both seem to have similar performance characteristics.

i went through a BIG ordeal with my oil & what type should be used.. i took my evo in for service... i got home read the service write up & it said they used 5 qt. of VALVOLINE
i was furious & it was after hours so i boiled on it all night. 8:00 am the next day i called the OWNER of the dealership (who just happens to own a mr himself) and he assured me that it not only was ok, but it outperformed moibil 1. still i went back & got my oil switched out for some mobil 1. if it ain't broke don't fix it

A couple years ago they had what they called TriSyn, which probably contained PAOs, esters, and hydrocracked base stocks. Then they went to SuperSyn, which they said "included PAOs". Don't know much about their current formulation or the new "Extended Performance".

That is right Mobil 1 10w-30 has a HTHS of 2.9 the low side of a 30w. The TBN is only 5.0 The Evo shears the oil down to a 20w, not good for bearings. Look for a full-synthetic that has a HTHS of 3.5 or higher that will meet ACEA A3 specs. hard to find without going to a 40w. This is sort of a pickle for me I want to keep my Warranty and Mitsu wants xx-30W. I am looking at Synergyn 3w-30 or Amsoil 10w-30. I was using 5w-40 A3 spec oil, but trying to find a thick 30w that will stay in grade. The EVO is very hard on oil.

Yet when it comes to changing their spark plugs, they don't buy the one that came from the factory. Instead they buy less expensive NGK or Denso plugs. Why? If they are so adamant about the "it came from the factory" idea then why not everything else?
Just curious.

Most of the high-end cars that require Mobil 1 do it for the same reason, emissions testing. The first test sample is captured during the first 505 seconds of the run. Regular oil takes too long to get to operating viscosity. The hydrocarbon emissions (HC) standard is where the Evo needs help too. Look at the boost friendly squish area in the head. Some of fuel trapped in between the band and the piston will not completely burn.
