The preflight showed 5 3/4 qts of oil. Thirty mins into the flight, the oil pressure dropped from 60 pounds (bottom of the green arc) to just above the red line. I had been closely monitoring oil temperature, pressure, and level, as I had just had the oil changed and it had been using a lot of oil and indicated low oil pressure (was running 60 pounds, had been 90-100 pounds). I was returning the plane to have the mechanic who changed the oil and filter to find the problem. When the pressure dropped I reduced RPM and asked blytheville AFB for vectors to the nearest airport. They sent me to osceola (10 mi away) because they reported manila to be closed (manila airport was not closed). I made an uneventful landing at osceola. Two problems exist here. First, why did blytheville AFB report manila closed when it was not? Second, why did I, the one who would have paid the price had the engine quit, accept vectors to osceola when manila was within gliding distance? I gave up the position of PIC to the controllers.

Title: SMA WITH OIL PRESSURE PROBLEMS REQUESTED VECTOR TO NEAREST ARPT. MIL CTLR VECTORED HIM TO ARPT 10 NM AWAY WHEN REPORTER SAYS THERE WAS A CLOSER ONE.
Narrative: THE PREFLT SHOWED 5 3/4 QTS OF OIL. THIRTY MINS INTO THE FLT, THE OIL PRESSURE DROPPED FROM 60 LBS (BOTTOM OF THE GREEN ARC) TO JUST ABOVE THE RED LINE. I HAD BEEN CLOSELY MONITORING OIL TEMP, PRESSURE, AND LEVEL, AS I HAD JUST HAD THE OIL CHANGED AND IT HAD BEEN USING A LOT OF OIL AND INDICATED LOW OIL PRESSURE (WAS RUNNING 60 LBS, HAD BEEN 90-100 LBS). I WAS RETURNING THE PLANE TO HAVE THE MECH WHO CHANGED THE OIL AND FILTER TO FIND THE PROB. WHEN THE PRESSURE DROPPED I REDUCED RPM AND ASKED BLYTHEVILLE AFB FOR VECTORS TO THE NEAREST ARPT. THEY SENT ME TO OSCEOLA (10 MI AWAY) BECAUSE THEY RPTED MANILA TO BE CLOSED (MANILA ARPT WAS NOT CLOSED). I MADE AN UNEVENTFUL LNDG AT OSCEOLA. TWO PROBS EXIST HERE. FIRST, WHY DID BLYTHEVILLE AFB RPT MANILA CLOSED WHEN IT WAS NOT? SECOND, WHY DID I, THE ONE WHO WOULD HAVE PAID THE PRICE HAD THE ENG QUIT, ACCEPT VECTORS TO OSCEOLA WHEN MANILA WAS WITHIN GLIDING DISTANCE? I GAVE UP THE POS OF PIC TO THE CTLRS.
