How long has the sled been using a lot of oil, the 2000 500 XCSP's were set way to rich from the factory, I had one and the first time that I used it I went 90 miles and the low oil light had been on a while. I put a quart in it and the light still was blinking on and off. We had to adjust the oil pump way down, and I know a few other people that had that problem when they were new. If it just started doing it then it could be something different.
