Should I be adding zinc to the crankcase oil of the '49 V8 in my '41 coupe?

Yes - you can add but easier to purchase oil made for classic cars.

Here is a thread with a link to a video that came up recently.  Seems logical and makes sense to me.  First time anyone ever seemed to explain anything.  Most of the time its just one of those things that you have to do and no one really seems to know why other than marketing people seem to put a lot of effort into telling people you need to buy their product.

I'm not telling you one way or another, do your own research and make up your own mind how to take care of your equipment.
