Elizabeth I love to read oil threads. The fringe and NOAACK numbers are totally a roaring laugh.
Anyway, I just would say Mobil One is a huge billions $$ company and they sell endless quantity of oil. No websites dedicated to "how Mobil One ruined my car' except in threads like this as innuendo.. and claims it sucks by folks 'selling' some strange brand made by virgin prima donnas on the moons of Jupiter.
Which naturally makes it a superior product. After all they post NOAACK numbers..LOL

Anyway Mobil One suggests the Extended life oil 5W30 for the ST. I wonder if that is only to cover the extended interval? Or is the oil better? (it does have the GM 'dexos 1' rating.)
I went and looked at the Mobil One site.
The Mobil One Advanced Fuel economy oil in 0W30 also has the dexos 1 rating, and Ford fill comment.
The Advanced has lower metal (Zinc Phosphorus) numbers than the extended interval, and a lot lower than the Euro spec oil.. (Just to compare things I know nothing about)

For the love of god, you don't read well do you?

My claims are for Mobil 1 5w30 on turbo vehicles only.

I showed proven data. I don't give a shit if you used different weights on different vehicles for different purposes.

If someone wants to run Mobil 1 5w30 and send in a used oil analysis to see how much it shears, please do so for the sake of data collection. Tom and I both agree about running the more durable oils.

Oil temps measured at the sump over 260 are common place for track day participants. Spot temps will be higher. Viscosity measurement procedures that end at 212 aren't too useful.

Remember, the SAE (label) viscosity tests stop at 212. That is well below what your oil will run when on track.
