A 10w-30 high detergent oil is probably the best for your engine. The multi viscosity oils lubricate very well at all engine temperatures. Buy a brand name that has the API designation. This will ensure that the oil meets a minimum specification for lubrication. I don't buy into the ZDDP requirement. The valve springs in the flat heads have much less tension than the springs in the high performance engine that were have camshaft wear when the ZDDP was reduced.. The synthetic and synthetic blends do a better job of lubricating than conventional oils and I have started using Mobil One in my cars. I noticed a big improvement in engine performance on my Lincoln and have not driven the Mercury enough to give an opinion on using it in a flathead.

Fords back in the day used oil with ZINC in it to protect flat tappet cams; one can still buy it; I use 20/500 racing oil with zinc. (in Florida)

Back in the day the oil used had ZINK in it. It's readily available most anyplace. The zink "protects a flat tappet cam;" which all flat head Fords have.

Use any brand you like, and any vicosity for the temperature you have where you are; but flat tappet cams;(all Ford Flatheads), require oil with Zinc in it to protect that cam!!

Just buy oil with ZINK in it! It's readily avialable; That's what a flat tappet cam; "FLAT HEAD MOTORS" need to prevent ruining the cam and/or lifters!!
