I put in 20/50 & i got
35 psi cold idle
7-10 psi warm idle
35 psi when driving

I had a chat with somebody yesterday & he said, crank journals could be oval or cam shaft.

I think low oil pressure at idle on an engine thats done a lot of miles is quite common. Some oil pressure lights are ON when idling

I think that low oil pressure at higher revs is more of a concern, or if it lights up on the motorway

I'll keep an eye on my gauge and see how it goes over the next year

I did rebuild my engine about 2 yrs ago.
