All fluids.
Parts. Front hub seals, front hub washers (I reckon you can re use them usually but Nissan call them single use), All filters (air, oil, fuel). Thats about it.
Check every moving part basically.
January 2013 is just about set in stone now.
V8 petrol only.
They were testing a few diesels but from what I know that is for the repowered Y61. I don't the the Y62 will have a diesel variant for a long time if at all. The V8 petrol (with cylinder shut down) will be more economical than any diesel they can produce at this time so can't see them doing one just for us rednecks. The guys in the sand don't want one and that is their major market.
