The stump grinders predator 459cc has bad oil after 10 hours. High iron, high aluminum and high silicon.
The lab couldn't get particle count as the oil was too dirty.
I'm going to throw the filter on there, run it an hour or 2 and retest. The filter I'm using catches 95% of 2 micron particles and 99.9% of 27 micron particles the setup will filter the oil around once a minute. So even after a few minutes, or by the time the engine warms up the oil cleanliness should be greatly improved. Shouldn't be much in the oil bigger than 5 microns after 5 minutes.
