I changed my oil and filter when my Cub had 2350 hours on it. The filter was changed again at 2450. I now have 2500 hours on the Cub. This morning I was plowing snow and splitting some wood. I idled down the tractor and the oil light started blinking. My idle is 100 rpm's below what it should be according to the manual, 850 rpm's versus 950 rpm's. I shut it off and checked the oil. The oil was full but ran like water. I changed the oil and got the motor back up to operating temperature. I then idled it down again and no oil light. I did more splitting and tried a few more times to get the light to come on. No more oil light. This leads me to believe that my oil was contaminated with ??? to thin it out. The tractor runs fine and has plenty of power. I do abuse it and not one to baby a machine. The antifreeze is full and I get great mileage out of the deisel fuel. The oil I used was 15w-40w Deisel oil from TSC. I did let the oil cool down before changing it. I wanted to see if it would be thicker. The oil flowed like a normal cold oil. Of course it was black as dirt and smelled like the usual deisel does. I can't have the oil analyzed as I dumped it into a very dirty pan with antifreeze and grit in it. The reccommended oil change time is 200 hours. I'm just surprised that mine crapped out with only 150 hours on it. Any thoughts or experience like this would be greatly appreciated.
