Re: Engine Oil
The guys at the shop that rebuilt my engine specifically suggested higher zinc level oil. I use the Lucas "Hot Rod & Classic Oil". Good price and no concern about the high pressure sliding surfaces on tappets and gears. Maybe the Model A does not have high pressures on the tappets? I do not know but I wonder how good the cam profiles were 90 years ago. Today's modern oils actually limit the zinc to very low levels and today's engines are made for that.
