I purchased an 08 g37 coupe 5at rwd earlier this year and I can't really trust that the previous owner took much care of it. Additionally, this is the first car I've owned that I will need to learn how to maintain.

My question is: what fluids (aside from oil as that's the only one I'm familiar with) need to be changed/flushed and more importantly - how frequently?

Please let me know if the ones listed below are the only ones I'll have to deal with:

Oil -mobile 1 synthetic -I will change every 3500-4000 miles
Brake fluid?
Transmission?
Differential?
Coolant?

Am I missing anything?

 

I would do the brake oil once a year and the differential every 30k miles atleast.
Coolant is long life and it's not required to change often. The transmission Nissan says not to change but guys on the forum here do change it out. For the manual transmission I change it every 20k miles just cause I do a lot of mountain fun runs and spirited driving.

 

Powersteering fluid.

 

The 5AT should be a bit easier to service, and unlike the newer 7AT it HAS a dipstick
