Saw on a Hot rodding show that the Lead additives are used for old cars w/o hardened valve seats. They also mentioned that those additives boost octane. Anyone know anything about this? The bottle says it's for off road use only. Usually something like that is pretty good. Prob. will clog up my cats, though.........

by the time you spend all the $$$$$ on additives you could have filled your tank up with premium fuel. leave it at the parts store buy the 92+ fuel. really its cheaper in the long run....my .20 differences
