I have a Volvo Penta Gas 4cyl

I have a Volvo Penta Gas 4cyl and when I was at full throttle my oil pressure was at 80psi. When at half throttle it drops to 65psi. At idle it runs around 30psi. I changed my oil and used 10-30 synthetic last year. I checked the oil after a few runs last week and it is very clear and clean. Should I change it again? Is that oil ok to use.

"Your oil pressure is just fine, VP states in the operator's manual a 35-85 psi range as a guideline. Remember that all engines have a drop in oil pressure when they are warm and a further drop with an RPM decrease.

FWIW, I was using 15W-40 on my 4 banger for several years with no problems. I used that grade because it increased the oil pressure at idle when compared to 10W-30 or 10W-40, especially after a long hard run."

"I have a B-30 engine in my sports car, and the oil pressure dropped to 30# at cruise, and 10# at idle. I have checked the oil pump, and it is like new (20,000 miles). Oil galleries are clear and a new mechanical gage has been used to varify condition.Pulled main bearing cap revealing no abnormalties. The valve train seems well oiled.I have tried different viscocities with no change.Any sugestions?
