Filled the oil cooler with oil then serviced the engine with aeroshell 100 mineral oil. Removed 1 spark plug per cylinder then turned the enging by hand several revolutions. Hit the starter and I got 70 PSI oil pressure. I repeated this several times to make sure the cooler and gallery had been purged. Replaced the spark plugs and re torqued. Put the seats back in the aircraft then programed the EMS with all of the engine and alarm paramaters.
