After you verify that you do have pressure at the higher RPMs your next
thought might go to the pressure sender. They sometimes do strange things.
Easiest way to test them is to replace it with a known good sender.

The oil pressure in my engine, a volvo penta 3.0gs from 1996, is gone
above 3800 when the engine is hot. I use multigrade 10w40 oil. What could be
the problem?

thanks in advance Jos
