I sent off an oil sample to be tested after 3 hours of run time, no filter. Told blackstone labs this was the first one ever oil fill, they said the wear metals were a bit high, 20 iron and 13 aluminum but to run it for 10 to 15 more hoursand retest. I installed a mobil1 filter and ran the wood chipper for 20 minutes and pulled another sample. The number of shinny metal flakes have been reduced from possibly hundreds of shinny metal flakes reflecting in the sunlight to dozens.
The mobile1 filters are a bit loose, only stopping 99% of 30mu particles. I think I'm going to put on a BT259 hydraulic filter which stops 99% of 12mu particles.
Note I did not change the oil after that sample, I'm testing to see if adding an oil filter and maybe a cooler can increase oil life dramatically, like 5 to 10 times.
