I'd like to hear more about Lead vs. lead free gas. I always thought it was a lubricant for the valve train and valve seats. Today they use "hardened" valve seats eliminating the need for lead in gasoline, but my 340 does not have hardened seats I was told I need to put a lead additive in to prevent wear.
