On BITOG Mobil is "known" for making valvetrains noisy.
Lots of reports from ppl saying its noisy with Mobil 1 or quiet with other oils.
I have not been able to find any reasoning behind it.
(Imagine an internetforum as big as S2Ki on oil alone
)
@ Wisconsin : the Visc of my Shell 0W-40 at 100C is 13.5 Cst.
According to a list found on BITOG all 10W-30 are thinner.
Here is a link to that list:

I really dont know for sure I'm going to use the 0W-40 again.. I might even go to 0W-30, to "free-up some horses" by the thinner oil at operating temp => less pump loss. That said, I still have another 6 liters of the 0W-40 sitting here so I think i'm going to use that up first. The UOA will hopefully provide me with some data on how my 0W-40 did in the F20C.

I am not a tribologist either, but the following is what I know:
0W40 oil isn't thin; however, it will shear slightly greater than 5W40 and 10W40 because of the high viscosity spread. On the other hand, a 0W40 oil only comes in SYNTHETIC form (group 3, 4 , or 5 base oil); so when it does shear it will probably be no greater than conventional 5W40.

SpitfireS I definitely want to see what the shear numbers end up at on your UOA. Most definitely post them and give us the mileage too!
