Actually the filter was from 2016 and I bought the machine then. I just found the receipt.They are really squeezing out a lot of HP on a small displacement engine on that exmark from other engines on the market. Anyways, the filter itself looks wonderful but must change the oil to remove the break-in metal. This filter was run back in 17' right?
I changed it and the oil at 5 hrs. These were from the days when my mother was terminally ill and I had no time for anything for over 5 years so I put it in a sealed container that I found just recently.
Since 2016 the machine had just about 10 complete oil and filter changes.
