I have a 2021 Uforce 600 with 29 miles on it. I changed the oil and filter at 20 miles and the oil was a light brown like it should be. I checked it today and my new oil is a milky colored. I live in North Dakota where it's pretty consistently below zero or near zero this time of year. I use my 600 for ice fishing and nothing else (no trail or water riding). I have not used or lost any antifreeze/coolant so I'm 98% sure I don't have oil and antifreeze mixing. I'm thinking I have condensation that builds up in my motor when it's so cold sitting outside. I do store it in my extra garage when I don't plan on using it for a few days but lately its sits on my trailer outside in negative temps since I've been using it every day. Anyone else have this happen from cold weather? I changed my oil again today and will see what it looks like after driving it all day tomorrow. Thanks

Although you can get a slight bit just sitting while the temperature changes, most of the condensation forms inside while warming up..much like exhaust systems. Once it comes to full temperature it will start evaporating or burning-off that condensation...however, if it isn't run long enough to do that, just like in mufflers, it will continue to build up. And it takes longer then people think to get rid of all of it. I suggest taking it out for at least a 2-hour ride once in a while. Before you do though mark on the recovery tank where the fluid is now...and check the weep tube off the water pump to ensure what leaks through that high-quality mechanical seal can get out and not make it past the oil seal on the other side.
