My used 2011 rzr is running great. We have put 800 miles on it in the last month. Mostly cruising logging roads and trails. Some hard pack also. So far I’m impressed with no failures. It has approx 2000 miles on it now in total. The only concern was some oil usage. 200 mls, or 6.5 oz’s. Is this acceptable over 800 miles? Should I be concerned?
