Hi Guppy,
How can the oil pressure be adjusted up?
I am having pressure problems oin an O-200 that has 80 hrs SMOH. Have just changed to Aero80 oil and suspect too thin for summer use, 22degC ambient here. Temp rising to 100degC. As temp rises pressure drops, about 20PSI in the climb and can drop as low as 10PSI in the cruise.....
Firstly am going to change to 100 oil and then think check oil pressure relief valve.
Any thoughts?
