My preferences.
Valvoline racing 30 wt. Any good detergent 30 wt will do.
Water soluble oil for the radiator in distilled water. Sold @ auto parts stores as "anti rust & water pump lube."

Buckle up. Many opinions coming.

Ford recommended what amounts to 20W, but what did they know about Model Ts?

As stated: 10W 30 oil and 50/50 coolant. Don’t bother with non detergent 30W. Gets too heavy in winter. Experience talking here.

Save your money and go to Wal Mart, Auto Zone, Oriellys and buy their store brand 10w30, or 10w20 HD oil. It’s much better than oil Ford ever put in Model T’s.
