The oil that I use in my old Ford Flathead V8s is conventional Pennzoil High Detergent SAE 30 straight weight. Along with this oil I use an additive to provide the ZDDP required in older flat tappet valvetrain engines. One such additive that provides the required amounts of zinc and phosphorous is Red Line Engine Oil Break-In Additive. My reasons for doing this are: The straight 30 weight is less likely to contribute to leaks and oil burning, adding the additive to the oil is less expensive than buying racing oils to obtain the ZDDP and the conventional oil has other additives intended for street driven vehicles that racing oils don't include. If you have a 1937 Ford with the stock, unmodified engine, you won't have an oil filter nor a proper seal at the rear of the crankshaft. To keep your engine as internally clean and healthy as possible it would be best to change the oil every 1000 miles.
