I use Royal Purple 75W-90 in the trans. on the Harley, which is a 94 Ultra Classic. I just had the engine rebuilt and am using Mobil 1 V-Twin oil in it. I plan on using the same Royal Purple in the gear case and trans. on the Polaris. Any reason I shoudn't?

 

I wouldnt use anything but Polaris AGL chaincase lube.The Polaris transmission is really a chain case and needs a light wieght synthetic lube.The best way to discribe the tranny is it is simarlar to the old GM 4x4 transfer cases.

 

Well, it does make sense to use what they recommend. After all most likely this will only be done once a year anyway. I believe that is sound advice.

Thanks
