Am doing an overhaul of my motor, new rings, valve job, four new SS valves for the exhaust. Rods & mains are all fitted and snug, looking at the main oil feed tubes with gravity feed make me realize that these bearings could starve of oil in cold weather at startup and 'till things warm up. I'm going to start with 5-W20 oil and may keep using it, we'll see how this drains from the rear main down it's tube into the pan. It works in the new cars and will work in the Model A if things are good, I also always add a half pint of 15-40 (diesel) oil to the fill, this give some EP for the camshaft & tappets since modern oils are now lacking.
I use 80/90 in rear end & tranny, have also used HI-Tran or universal tractor fluid in them, never use the old crap stated in old books, modern lubes a FAR superior, use it, I've driven the A since 1948, ain't the first rodeo.
