[VAC] Re: Vintage haulers and unleaded fuel

["Richard P. Kenan" <as5368@xxxxxxxxxxxxxx>]

         As I understand it, the lead additive (tetraethyl lead) was an 
inexpensive way to improve the knocking qualities of the fuel, i.e. an 
effective increase in 'octane' rating.  Getting the lead out of the gas is 
simply a matter of not putting it in, as it was an additive.  The expense 
associated with unleaded gas, aside from the current 'summer blends' we use 
here in Atlanta, is is attaining the equivalent octane rating without the 
lead.  So, I don't think your friend is correct.  Besides, IMHO, things are 
never that simple and clear cut.
