Oil pressure too high
I have seen high oil pressure on my last flight. It was near 90 psi all the time (Cessna 172S). Before it was rather in 50-70 psi region.
The oil is AeroShell 15W50, changed in October and flown about 15 hours since.
I was told the lubrication system could be blocked on some place. That would be bad.
Any ideas?
