I know M1 is considered to be the best oil, but it never was a good oil for the Vq35 engine. Another reason to not use M1 would be that it is no longer a true synthetic. Several months ago they changed their formula.
Mobile1 is no longer a true synthetic
Mobil sued Castrol for calling their oil a full synthetic. Which according to Mobil it wasnt a full synthetic like M1 since its not made from a Group IV base stock.
They lost the case, so they decided to start using the cheaper base stock just like Castrol,pennzoil etc. Why make a real synthetic that costs you more money to make then the competition who is charging the same price for their fake synthetic?
German Castrol Syntec 0w-30, Amsoil, redline are some of the few remaining TRUE synthetics( Group IV). The other Castrol syntecs, penzzoil platinum and now Mobile 1 are not TRUE synthetics. They are hydrolocked Group III oils.
Here is an example of how even yellow bottled Pennzoil Dino outperformed M1 in our engine.
M1 used to be a great oil, now its an overpriced fake synthetic. My current fill is German Castrol Syntec 0w-30 (auto-zone only). Unlike the other castrol syntecs it is a true Group IV oil, here is an oil analysis on a G35 coupe. As you can see this oil shows very little wear after 7500 miles.

I am skeptical that the lead and iron numbers you have highlighted prove anything. What about the readings for Moly, Silicon, calcium, phosphorous and zinc, which are all higher with penziol? Also, how do you reconcile the difference in mileage between the Mobil and Penziol tests? How hard were these cars driven and in what conditions? The only way you can draw conclusons from such tests is to have two identical vehicles driven in similar conditions in similar driving styles. Otherwise the data is not comparable and any conclusions are suspect.
There are many studies out there that demonstrate that, except for extremene cold conditions, the type of oil is not the major factor in engine wear. Rather, it is the frequency of oil and filter change that is the significant factor in engine life.

hey guys 3 of us here just changed our diffs/and engine oil using amsoil. ts0 0w-30 for engine, all i can say is wow i def can tell a difference, runs alot smoother. i initially had mobil 1, then swapped to royal purple which i couldnt stand as it seemed to burn off quick and get dirty quickly. we will see how it does as i know one of use is sending it to blackstone when the time comes.

Sent mine in yesterday... ran 4000 miles on mobil 1 10w-30 clean.. (regular dino oil)... replaced with castrol syntec (full synthetic) 5w-30 and will resend in 5k miles to see the difference...

another oil test: http://www.animegame.com/cars/Oil%20Tests.pdf
I am currently using valvoline and I am happy. Seems like the engine works better then on castrol.
