In the summer when it's always over 60° F engine starting temperature I use S.A.E. 40. It gives a little higher oil pressure. Between 32° F and 60°F starting temperatures S.A.E. 30. We get colder than that in the winter here so I'm trying 20W-50 this winter. Still seems like the pressure is low. But, as I say. I don't think pressure is critical.

Typically a good running temp is over 180, till it goes to 210, Thats why they say you need to drive them not just idle them in the garage. Flatheads dont need a lot of oil pressue at hot idle, if you hit 20s hot idle you are doing very well on a stock motor.
I good infrared temp sensor is a nice addition to the toolbox too. Many uses, from testing your ham sandwich to detecting blocked raditors.

Dear Friends!
today my engine has been running during 40 min. So I took pics when I arrived home, I tested with infrared temp sensor too that is according with mechanical gauge.
I installed SAE 15w-50 we are in summer now.
tomorrow i will run my engine for more time in order to have more info.
I will be back with news.
Thanks
Hary
