Thanks for the replies, I got it cleaned out now. On the third oil change I added about an ounce of MMO and the oil came out alot cleaner, then on the fourth change it drained out nice and clean. Filled her up with fresh oil and called it done. Just for general info, I started with buying quarts of compressor oil @ 9.99. I found a gallon @ O'Reily's for 12.99. In the past I used to buy straight 30w non detergent for compressors but you can't find non detergent oil anymore. Oh, I did stick an air nozzle in the fill hole on the last drain and it helped in pushing out all remaining oil. Thanks
