That's a load - and totaly contrary to the Owner's Manual. I have my mechanic do my oil changes (for warranty documentation pourposes - do the oil changes myself on the other Z's) although that's not required. I have no idea where he got the idea of Mobil 1 as being the "other" acceptable oil since it doesn't have any Ester at all in it (Class III only).
I talked to my dealership and they said in all the G37's (our VQ37HR engine) the only time they've used the Ester oil is for the TSBs - never had a single client do an Ester oil change in the last two years.
