Trail Ridden ATV OCI

[belbers9715]

Hello all,
We are getting to that time of year where I get my Outlander out for the season. I was wondering what everyone does for OCIs. I currently have Amsoil 5w40 ATV oil and a Wix filter in it (from their oil change kit). My initial thought is every other year will be fine, as I only am able to ride roughly 300-500 mi/yr. Are there any particular oil concerns with ATVs? (fuel dilution, shear, etc) Should I do a UOA?

I'd change it once a year.
Amsoil and most all atv manufacturers recommend an oil change annually, regardless of mileage.
Moisture is probably a real concern, and after a year, it is likely TBN is depleted.

I do my engine oil and filter and gear oil in the diffs annually on my atv's.
