Oil pressure

[Fred n' Ethel]

Hi folks.
In your experience, what does the following info indicate regarding the condition of my stock 1954, 235.
Outside temp 85f, 20 mile warm up city and highway.
Coolant temp never up to the midpoint.

Following oil pressures are est. from the stock 0-60 gauge.
At idle - 5 ish psi.
In 3rd gear, 25 to 30 in town - 10 to 14 psi.
Highway speed (50 to 55) 30 to maybe 32 psi.
Using straight 30W oil (100 mi. old)

Changing the oil soon, what would you recommend ?

Thanks
