Re: Modern Fluids??

So here is another question on fluids. I have read the previous threads on this issue but I am still a little fuzzy on this one. Gas...... (grade, and lead or no lead). What was specifically called for in 1951 for the "300"?? I have been told that only leaded gas was available back then, is this true? To get the thing started I dumped 5 gallons of regular unleded (87 octane) in it (no lead additive) and it is running like a dream, now granted the car has only run for about two to three hours (and at idle at that) since I got it running. But I guess the reason that I am asking this question is that I am trying to look forward to the long term on engine wear. I am trying to baby this engine as long as I can so I will not have to rebuild it due to premature wear that could have been easily avoided.
