My 1937 Ford with the original flathead would produce 60 PSI oil pressure after cranking for 5 seconds. It usually sat in the garage for at least a week between being driven, sometimes much longer. Thats about 10 revolutions of the engine to get that pressure.
It had a start button that would crank the engine with the ignition off, so I used that to prelube the engine.
No oil filter. 80 year old technology. 6 volt system with starter cranking at 100 RPM. less that half the cranking speed of a modern engine.
I never wait after the engine is running, not even a second, just enough time to put it in gear and go. I might change that if it was 20 below, but that will never happen here.
In fact in the .3 mile from my garage to the main road, through the neighborhood, I will pulse up to 35 and glide to the stop sign, and my mileage reading will INCREASE during that glide even though the engine has been running for about 30 seconds from a cold start.
It's also 10 feet vertical rise from my garage to the road in 80 feet distance.
