I just picked up my 05 g35 the other day and the car came with no records at all so I have no clue what has and hasn't been done but I want to do whatever prevantitive maintenance to keep the car reliable...the car has 92k miles so what do u guys suggest I do. I'm changing belts,oil change to penzoil platinum full synthetic 10w30 as well as a tranny flush this week...what else should I do? Thanks in advance

 

welllll I changed everything at 47k which was probably over kill...

I changed the oil, tranny fluid, diff. fluid, coolant, brake fluid, clutch fluid, and my brakes

 

What should you do? NOT use Penzoil anything! If you want to maintain your G use a quality synthetic like Mobil 1, Red Line or Amsoil. As you can tell I'm not a fan of Penzoil and wouldn't even use it in my HONDA lawnmower because I respect all thing mechanical. Don't forget about your differential that fluid needs to be changed too....

^don't trust castrol syntec either?

 

i was reading that oil comparison thread on my350z and the guy who made the thread and gave all the details about diff oils suggested penzoil platinum as a good oil so i bought it loll...why is it bad?

 

I'm sure if you follow Infiniti's 90,000 Premium service you'll be fine. Do a search for Infiniti's recommended maintenance schedule.

From what you listed I don't think a tranny flush at 92k is a good idea, and drain and refill would be more appropriate.

 

Castrol syntec is excellent oil for the VQ I am currently running it. I have sent it to blackstone labs for analysis and it came back very good.

No reason not to run it. Nothing bad about it. And its not the only oil that's good. Amsoil and mobile 1 are good aswell.
