All,

I posted yesterday and did not really get enough info on what services should be performed at 30K on 2008 G35xS Automatic.

I did quite some research on this forum and there seems to be no consensus.
The bottom line, should the following services be performed at 30k, as they are listed under Premium maintenance in the service manual or these are overkill?

o Replace automatic transmission fluid
o Replace differential oil
o Replace engine coolant/flush system
o Replace engine drive belts
o Replace radiator cap
o Replace transfer case oil (4WD/AWD)
o Optional: flush automatic transmission (flush with ATF)

Thank you, all

 

If you lease the car do what is required in the maintenance book. If you own the car I would do the Premium service and do what you listed.

you can flush with ATF which is like 12-13 quarts or you can Drop the pan and fill which is like 3-5 cant remember. I personally flushed it.

 

IMO, differential, coolant flush, radiator cap is an overkill. I would personally just do an oil change and maybe AT drain and fill, and check the engine belts condition, if they need changing only then would i change them otherwise not required.

I am personally @ ~50k and belt still seems pretty good, however there was this one uy whose belt gave out around 30k i believe.
