Leaded gas vs. Unleaded Gas.
 

How do you lowmile supercar owners run your cars? Since gas in no longer leaded. Do you have the heads redone? or what? I know there is lead additive but does that do the trick? Just a thought [img]/ubbthreads/images/icons/grin.gif[/img]

The good ole Bronx. Dunno if you can read the print on the side but they say Jun 69. It was purchased 6/6/69. So she was new and PURDY. Unlike today. See attachment. [img]/ubbthreads/images/icons/frown.gif[/img]

Everyone will be different on this one, but I don't use anything on my personal cars, even if I know there aren't hardened valve seats. If I was planning on hammering the throttle I might add a tankful of additive, just to be on the safe side, (its my understanding that aggressive driving causes more heat on the valve seat area, exacerbating the degradation.) But mostly I just figure I'll drive it until the seats give out, then do the proper new-valve-and-hardened-seats thing later, if necessary.
