oil

I'm about to do a full service on my '05 700 EFI and am going to use Amsoil 4-stroke 0w-40 synthetic engine oil with a Wix filter, and the proper Polaris fluids on the front and rear gearcases and transmission. Polaris indicates that any GL-5 80w-90 gear oil is fine for the rear gearcase, however. I have yet to find a substitute for the hub fluid for the front gearcase and am not sure what, if any, ATF will work in the transmission.
