Mule 4010 W/ fuel injection gas and oil in air filter
 

We have a 4010 Mule w/fuel injection that has what I believe to be gas and oil mixed in the air filter..it is a gray liquid that smells of gas. It only has 200 hours on it, and we only use it a few minutes everyday to dump manure. Anyone have thoughts??? Scared to death it will cost an arm and leg to fix!!

Is your oil overfilled also? It could be the crankcase blowing fuel into the intake because it is overfilled. An engine runs "rich" cold by design. If you always run it on short trips it's putting excess fuel into the engine. Ideally you want to let it warm up for a few minutes on each trip to burn off the excess moisture in the engine.
