First off, I ALWAYS use synthetic and have for the last decade in all my vehicles. The only thing that keeps our trucks from grinding to dust is a thin layer of oil....
That said, I use Amsoil Severe Gear 75W-90 in the front and Severe Gear 75W-140 in the rear (Dana 44).
I use Redline for the transer case however. D4 ATF. It's slightly thicker than Amsoil ATF and is GL-4 extreme pressure rated (which is awesome)!
Alright, i am new to Nissans, but definately not new to cars, and when checking out my power steering fluid it appeared different (red?) than what i had on the shelf. Looking on here it says that i need to basically use Dexron 3 (or similar) transmission fluid in my power steering? On Amsoil's website it says that i need to use a synthetic automatic transmission fluid.
