Hi Alan,
That does seem low. My engine is a 912UL and has done 580 flying hours and
I still get 4 bar at 2000 rpm when hot. Unless you have run a bearing it is
probably a weak pressure relief valve, or faulty pressure sender. Because
the senders are known to give trouble and are subject to vibration, I have
mounted mine on top of the footwell and have fitted a low pressure warning
light as a backup. I use Shell Advance VSX4. I hope it
is nothing more serious than that.
Regards,
William
