What oils are you guys using in your 07 G35's?

 

Castrol GTX 5w-30. Not the fanciest oil in the world, but good chemical composition, and my last two cars have run like watches on it (I change oil and filter every 3k miles). The G just had it's first oil change too

 

im planning on running M1. it never let me down in my previous car. are there any procedures i have to take by going synthetic?

 

Does anyone one know what oil Inifiniti uses when you go to do your first maintenance? This is going to be a big issue for me because ive only used Mobile 1 synthetic on all my previous cars... I just hope the dealerships dont use some crap

 

I think my Infiniti dealer uses Valvoline products so I guess they would have their synthetic as well.

 

Many dealers carry name brand synthetics in addition to the Nissan brand products.
Most will also install your brand of choice.

I used Amsoil in my G;
I used to take it with me & the dealer charged labour only for the change.
