Narrative:

While flying overhead casanova VOR in a piper turbo arrow III, I noticed that oil was coming out from the top of the cowling and splattering on the windshield of my airplane. I then looked at my oil pressure gauge and saw it dropping. I then radioed the manassas tower, declaring an emergency. At that point I had 3 options that I was given by ATC, culpepper, warrenton, and manassas. I chose manassas, seeing as that was the airport I knew best, the only controled airport, and where I would be most likely to get the assistance I might require (fire trucks and rescue vehicles). I did land the airplane safely. However, I was considered in error by the FAA for not having landed at the closest airport. The cause for the oil leak was that the oil filler cap had come off due to rust and corrosion on the inside of it.
