does anyone know what kind of clutch fluid is good to use on an 06 g35?..do you use a dot 4 or dot3 brake fluid for the clutch because in the owner's manual it says use a dot3 but on this other thread on changing the clutch fluid, it says use a dot 4.

 

Both are fine. I replaced my clutch fluid with dot 4. Honestly, you'd probably never know the difference.
