I forgot to add that I live about 40 "miles" east of San Francisco.
I also forgot to ad that my engine is a new rebuilt with less that 10,000.
I'm not sure if that make a difference or not but I thought I would mention
it. I've been told that my oil pressure runs a little on the high side. I
wonder if this is because the engine is new so to speak.
