Just purchased a 2018 CForce 500 HO, 980 miles.  Took it out a couple times and the Oil Pressure light started flashing.  No smoke, no change in performance.  Checked oil and it was a little low so I added about 1/3 quart of oil.  Still flashing.  Checked oil pressure sensor, blew it out as mentioned on this forum.  Still flashing.  Thought I read somewhere that it may be an "Oil Change Indicator", but can't find anything about this in the manuals.  Any help on my next step would be much appreciated.
