On a flight between Deming, NM and Sierra Vista, AZ, today, the oil temps on my Superior O-320 D1A fluctuated between 150 and 387 degrees. The fluctuations occurred very quickly. All other gauges were in the normal (green) range. Could this be a bad sensor or has anyone experienced a similar issue with a different result?![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
