XPT oil reccomendations

Just picked up an orange XPT, wanting to change the front diff, rear diff and engine oil. I’m an amsoil dealer so I planned on running 0-40 in the motor, the amsoil front drive fluid and the trans & gear case oil. Does the motor hold 3qrt on the XPT? I’ve only got 2hrs on it so far, probably going to go ahead and do the diffs and wait until 10hrs to do the motor. How’s that sound?
