No Full Synthetic Oil in the Z?

370Zsteve

So, again, Nissan highly recommends (can't require, by law) the oil but does not use it themselves for the factory fill, which will be used during the most crucial period (break-in) and which would help limit the number of warranty issues with the engine? Really? Man, that is one dumb company.

The TSB, by the way, states that Nissan Ester oil is required when reflashing the ECU under the TSB procedure for the 3.7 VHR. Isn't the ECU reflash at this point done at the factory?

EDIT: Nissan Technical Service Bulletin ITB08-028a
EDIT: The Owner's Manual was written long before ITB08-028a
