So I took an oil sample from the Cummins 8.3L in our 821 Case front end loader. We use this loader on our farm mostly for loading the feed wagon to feed the cows. Trying to figure out where this high fuel is coming from. Using Service Pro 15w-40 oil. 370 hours on the oil.

Soot .2%
Fuel 5.8%

The last UOA I did was back in April and had 320 hours on the oil. Fuel was high in that case as well at 4.6% where most other levels were about the same. I thought it might have been the fuel pump, which is driven off the cam shaft, as I had issues with that in the past which put my fuel over 10%. I replaced the fuel pump but still have a lot of fuel in the oil. This time of year, it idles a lot to keep the cab warm in the winter but I doubt that would cause such high fuel, especially when the last UOA was in the spring and still had high fuel. I had the injectors/injection pump gone through fewer than 3000 hours ago so they don't really have that many hours on them.
