Hi guys

I will do an oil change on my RZR and I choose this synthetic AMSOIL oil plus a KN filter.
it meets the specs from Polaris so I should not have a problem, right?

just thought I'd share with the group in case anybody had a bad exeperience

I've used Amsoil in my RZR for 3000 miles and 160 hours (all year round AZ weather) with no problems. I change it every 50 hours and it looks good coming out.

As for higher weight for hotter climates, I don't do that unless it states it in the manual for any vehicle I own. I don't do it mainly because of small orifices that may not be designed to flow thicker oil, therefore starving some engine areas of oil.
