Hello,
I have a Superior XO-360 with ~200 TTSN
20 minutes in to a recent flight after normal oil pressure during run up and take off, the oil pressure warning alarm sounded. The oil pressure read 101 on the Dynon D10 EMS.
I backed off on the RPM and pressure remained high for a bit then came down to low 90s then back up to 94.
I landed at my home airport and tested the oil pressure sensor with compressed air and it was functioning normally. All pressures on my air pressure gauge and the Dynon were within 1-4 psi of each other. This rules out a transducer issue. Yes, I know that Dynon now uses a different transducer, but this is not the issue.
I backed the pressure regulator screw out about three turns and lowered the overall pressure for idle ~60 psi and ran up to 2000 rpms and it was ~84 psi.
I flew a couple of subsequent flights and the pressure was within normal limits ~80-85 in cruise 24x24.
Today I flew with a passenger and the pressure on takeoff roll was 101 and only came down to about 97 in cruise the alarm was sounding during the whole flight. I backed off prop RPM and it remained in low to mid 90s.
Having ruled out the pressure transducer, what else could be causing this?
Thanks in advance,
Mike
