Scrapman1959 Posted August 14, 2016 Report Share Posted August 14, 2016 2011 CTLS with 1040 hrs TT. Oil pressure gyrations has been getting steadily worse with today's flight seeing 23 to 55 lbs In wcruise. The needle moves rapidly. Connection on the sender is clean and tight. We did the extra grounding years ago. Engine oil is full as always, and engine sounds normal. Any ideas guys? I was going to replace the oil sending unit for starters.
