Gator 620i gas in engine oil
I think there is a post on here somewhere that deals with your problem. If I remember correctly I think they replaced the computer or the throttle body. Ask your dealer if there is a bulliten on it, I know I've seen it on here.

Gator 620i gas in engine oil
I think AllisMan has the problem diagnosed, but getting an O2 sensor on an XUV is out of the question. There must be another variable in there also because some are way worse than others. I have experimented with my XUV and put a piece of cardboard totally over the front of the radiator. I don't use mine to do any heavy work, just riding around, but I have yet to have the cooling fan come on. I believe the cooling system is overkill and won't let the coolant get hot enough to let the heater work properly let alone turn the fan on. I think total blockage could be tempered with partial blockage according to work load, but I think there needs to be some restriction to get some heat in the motor, which Deere is telling you to do in the first place. I know if mine ever got hot enough to turn the fan on I would have to cut a small hole in the cover ( cardboard ) to let the fan do it's job. Maybe another idea would be to turn the heater fan on high and see if that would cool it down. Oh yes, I have tried my fan in a closed situation and it does work. I have changed my oil also. I detected a gasoline odor and the oil was brownish, but the viscosity did not seem to be compromised.

Gator 620i gas in engine oil
Gentlemen, Allisman figured it out a year or so ago. The motor has no O2 sensor so the computer dumps gas in there at the same rate all the time. How can a fuel injected motor operate properly without an oxygen sensor? It can't. Deere isn't going to retro fit every XUV with a computer, O2 sensor and wiring harness to fix the problem. So they make up lies to try and appease the poor owners that are complaining. They made a mistake and are not owning up to it, or making any attempt to really fix it. If you have an XUV,cover the radiator up until the red light comes on then uncover it a little bit. Mine is almost completely covered and the fan doesn't even come on.

What you say makes sense. I think the problem is when the motor is warm and not to the hot stage, that could be where the sensors are. If the sensors think the motor is still cool they will keep it rich. I think an O2 sensor would cut back on the fuel in this range. I know there are other sensors on it. The main problem is the motor never heats up. I just don't think Deere did enough testing before they put it in a Gator.
