On a flight last week I had a -19psi change in my oil pressure, the majority of change in 6 seconds!
No alarms sounded as the oil pressure was still in range but picked up on it and made an immediate turn to more favorable landing zones as it was still slowly trending down. During the turn I was also changing power settings and looking for oil when I noticed the pressure coming back up! Located a safe path to the nearest airport but the pressure was rock solid from then on. On landing the oil level was at 5.5q, about where expected so there was no unexplained oil loss. The event lasted over a minute and I see nothing in the data that would suggest this was instrumentation.
The only conclusion I can reach is the oil pressure regulator must have gotten something on the seat or just didn't seat properly until I shook it loose with power and g load. Weird considering this was 10+ minutes after establishing a climb profile.
I attached the Savvy flight (11 minutes in) for those who may have more insight into this anomaly.
