Does altitude affect indicated oil pressure? I have the full house Electronics International engine gauge package and while out flying today (5 hours and counting toward 40) I noticed the oil pressure was down from what I had been seeing. The oil pressure has been set to maintain about 83 PSIG at 2500-2600 RPM but I had not flown over 3000' due to the weather until today. Today I was at 6500' and the oil pressure was down to 79-80 PSIG. Obviously this concerned me due to the freshly overhauled engine and I had visions of oil leaks, rods coming through the engine case, ect. When I let down to 3000' oil pressure came back to the values I had been seeing before and were stable. Is this normal? For the life of me I cannot see how ambient pressure would affect the gauge reading, but it appears it does.
Did I mention how great this airplane is? I have never flown an airplane that becomes part of you when you strap in. It is undescribable.
