1947 Mack 75 Fire truck with gasoline engine, Is a lead additive required in the gasoline ? I have used it for years I was told recently not so if using a premium fuel. I thought it is required to lube the valves regardless of fuel grade. Any one have an idea on this topic?

You guys are great! Thanks for the help.

Hello All, I am representing the Tallmadge Historical Society (Tallmadge Ohio). We have a 1947 Mack model 75 Pumper, its in good condition for its age with a few problems. We use it as a parade vehicle. I'm hoping that I may use this forum to keep this rig running, so I'll be putting up some posts asking some tech questions as well as looking for parts. As soon as I can get a hold of a digital camera, I'm Gonna post some pictures for all to check out! Oh Yea, I only fix it because they let me drive it!!!
