I changed the motor oil in my 2008 RZR and, per the owners manual I put 2 quarts back in. When I checked the oil it is about a quarter inch above the full mark on the dipstick. When I dumped the old oil from the drain pan into the oil bottles there was only about a quart and a half. It was full before I drained it. The manual says not to overfill. My question is this: should I drain a half quart out or will the half quart do any damage? Thanks in advance for your advise.
