Castrol Syntorq

Are people getting away with using something else (read "less expensive, more readily available) than the Castrol for their NAV4500?.
TDR writers have recommended changing the oil once in a while and the owner's manual states that it never needs changing. What is the experience in the field?
I don't really "use" my truck. I just drive it. If the recommendation is to change the tranny fluid once in a while, at what interval?
