My 60 MPH
oil pressure is 75PSI, 40PSI at idle. I am running a
oil cooler and 8 qt pan so the temp. never exceeds 150 degrees. I would look at 15-50, or 20-50
oil in the summer, then get rid of the stock 5qt pan you have got . With the Unique you can change pans and pick-ups easily. You may want to look at a Canton 8 qt. pan, road race or regular. My thoughts. Drop in oil PSI is a result of the hot oil and not much of it, alot of oil up in the engine.
