Ok thanks for the info! I think I will probably go with Maxima Oil and the Polaris Oil filter.Polaris filter is good. I did notice on the Maintenance manual there are two filters for the polaris. Both will fit but one is longer than the other. Amsoil filters are also very good.
I used Amsoil 5W 40 for my 2006 VW Tdi diesel. Close to every 40,000 miles cambuckets destroyed & and cam, needed to be replaced twice then I got rid of the piece of junk Car.I have 10,000 miles on my 2015 1000XP, most of it with the Amsoil and wix oil filters. Last oil change I tried Mobil 1 5w50 and it seems to be working well. Nothing but R2C air filters since new, as I spent the majority of those miles in the horrible central Oregon dust. I have yet to find a speck of dust inside the intake tube.
