Unless you have a leak in your gauge line, these mechanical gauges are pretty close to right. Also, I have never been one of those guys that has been a big believer in synthetic oils except in my diesel trucks. But odd as it is I gained about 5-8 psi at idle when I switched to a good syn...who knows?
My oil pressure is way lower so i gotta do some diggin into it to find the problem.
