I understand it's best to just follow the recommendation. However, the manual for my G37(S) 2009 says "add Genuine NISSAN PSF or equivalent". The cap on the reservoir says "ATF Dexron". So which one should I use? Also I assume if it's ATF then Dexron II and Dexron III are both ok.

On Amazon I also found "Genuine Nissan Fluid 999MP-EPSF00P Electric Power Steering Fluid". Is there a difference between ELECTRIC PSF and just PSF? Or do they both mean the same? It that 999MP-EPSF00P what the manual refers to with Genuine NISSAN PSF?

Dexron VI is the equivalent of Genuine NIssan PSF according to the Factory Service Manual. Looks like Valvoline makes it for an off-the-shelf purchase.

Thanks a lot. After your post I googled the Factory Service Manual and it pointed me back to NicoClub.com . I ended up buying Valvoline DEXRON VI Full Synthetic Automatic Transmission Fluid. Amazon also had Mobile but that one is a blend which is probably ok. I didn't go with the Nissan one (999MP-EPSF00P) because it's Electric(!) Power Steering Fluid and I couldn't find and 1 quart (hydraulic?) PSF.

Is this right?

Dealer says I have a rack leak but reservoir is slightly above the max cold level. Not sure if they filled it during my oil change, will watch for a few months.

Is there any benefit to replacing the fluid in the reservoir with turkey baster method a few times? I had it flushed at independent shop 15K miles ago.

Good move. EPS is only for electric pumps. I don't know what it would do to a Dex6 system, but I know for certain that Dex6 makes a mess of the electrics. So my bet is it wouldn't go well.

Question:

In the past on my Altima, I just drain out PS fluid from resevoir, and put in new fluid

Jack up the car, start up the car, then turn the steering wheel left and right.

Is that a good procedure?
