This Stihl 010 AV chainsaw with a 16 inch blade is a great addition to your outdoor power equipment. It was manufactured between 1978 and 1985.  It was purchased new, probably toward the beginning of that period by my sister and she was the only owner.  The 2-stroke engine runs on gasoline and oil and provides plenty of power for your cutting needs. This chainsaw comes with one 16 inch blade. The saw has not been used in more than 20 years, but was working when last used.  It was used fairly regularly for personal use in the 1980s and 1990s.  This also comes with 11 bottles of Stihl branded 2 cycle engine oil.  There are 5 unopened bottles of 2.6 oz. each, and 6 unopened bottles of 6.4 oz. each.  Like the saw, these bottles of oil are old, but unopened.  This is about $41 worth of oil on Amazon.  Also included is a Dremel electric chain saw sharping kit.  I plugged in the sharping kit, and it turned on.
