Price per liter.  You need 10 for the GT-R trans.

Our fluid has a good amount of detergents in it to keep things a little cleaner, better cling properties to it so the gears are happier, and it is designed to allow for a lot of clutch slip while in the 'friction zone' without as much chatter as you see in the OEM or aftermarket fluids.  Pretty good and affordable stuff for a car at 900ft/lbs to the wheels or less.

This fluid can be used for longer intervals in the GT-R due to the added detergents.  Nissan recommends replacing the fluid every 18k miles, but we are comfortable allowing our fluid to go as high as 25k miles depending on driving conditions.
