I have received this info second hand on the new Mobil 1 formulation, called SuperSyn. Just bought some tonight :D
"Once again, the leader in the battle for world's best motor oil has
changed. Mobil-1 has released version 4. As you may recall, Mobil-1 version 3 (the "new, improved Tri-synthetic") was actually a big step down from the excellent version 2. But Mobil has regained motoroil leadership with version 4, called "SuperSyn" by the marketing nitwits, which, in its strange 0W-40 configuration has a VI (viscosity index)* of 185, surpassing the previous leader : ultra expensive and generally unavailable Castrol RS Synthetic 10W-60 (vi = 181) which is also known as Castrol TWS Motorsports or BMW 07 51 0 009 420. In this ballpark, the
oil film is almost TWICE as strong as the average non-synthetic !!!
*viscosity index = VI = this is THE best laboratory indicator of the
lubricating quality of oil, particularly in high-RPM motors like European motors or track cars. It is a dimensionless relative value that indicates how well an oil film can stay together
as a contiguous "sheet" in high speed sheer conditions (i.e. bearings, etc.)
So, anyway, I'm excited about this new 0W-40 formulation with
the super-high VI ...was actually designed for European cars. It is the factory fill in all Porsches and AMG Mercedes, among others. The "0W" part tells you that the stuff will pump up quickly into your motor during cold starts, even in winter. As far as hot / summer track performance goes, it will be the best for most
any condition unless you run uncontrolled very high oil temperatures (shame on you - buy an oilcooler), or possibly for use with turbochargers which have localized extreme emperature issues (in the turbo bearing).
If either of those cases are true (you run irresponsibly high oil
temperatures in the sump OR you run a turbocharged car on the track in hot weather), you may have 2 better options than Mobil-1 SuperSyn 0W-40:
1. Redline oil. Redline is a polyol ester instead of polyalphaolefin.
The very best at very high temperatures. We use polyol ester oil in the super hot, 60,000 RPM fuel pump turbines in our liquid-fueled rocket motors, such as on the Shuttle and NASA's other launch vehicles. And Shuttle motors are re-used many times.
2. Mobil-1 SuperSyn 15W-50. The VI of this weight isn't as good (155) and it doesn't pump as well cold, but it has better very-high temp. stability and Mobil has tossed in some additional anti-wear additives for race cars which they originally developed
for the NHRA top fuel dragster loonies. I don't think I would use this weight in street cars or even in track cars in anything but the most extreme circumstances (because of the VI).
Thanks go to the ExxonMobil chemist who donated alot of his time this morning to me."
