Wow, I thought 86,563 original miles on my 1948 was low! It's been to church and everywhere else. My dad bought this truck new too so that's how I know its original mileage. I rebuilt the engine 35 years ago and have run lead additive since the late 70's. It still runs beautifully. As R. Wyant suggests, the Marvel Mystery Oil is also used by many with success. But as everyone agrees, not running the engine hard is the best preventative.
Have Fun!
