250 cid oil pressure

What are done 250 cid oil pressures. Mine runs 25 at 55-60 and 10-15 at idle.

Re: 250 cid oil pressure

You need about 10 lbs per 1,000 RPM roughly, so you are good at idle. Usually low oil pressure shows up worse at idle than at speed so, having said that, I'd consider using another gauge to verify.
