I am at 108K on my 2008 G35 Journey and figured that it’s been so long since I can recall that I had my transmission drained and filled. I was also thinking about going ahead and changing the front and rear differential fluid since I will have the car up. I had a few questions about fluids, I have read through many threads but didn’t see too much information on the differential fluid that should be used.

I know that I need Matic-S for the ATF so I will get ahold of a Nissan or Infiniti dealership and pick it up up from wherever I can get a better price.

Do any of you have suggestions on what type of fluid would be best used for the differentials? I have the local auto parts store which carry it. But didn’t know which weight would be the best along with the brand like Valvoline or Lucas or maybe even something else.

Thanks for you help!

 

Nissan/infiniti uses Pennzoil, atleast the dealership here does. there is no oem fluid for some strange reason. I ended up going with valvolines synthetic blend. if u wanna be specific to the weight that came oem than not too many choices.
