Re: Leaded Gas
Virgil & Sue Klein
Tetraethyl lead was an inexpensive way to add octane to gasoline and also provided a cushion (lubricant) between the valve and the valve seat. I have had several older cars and have never used a lead additive. These would include a flathead in my ’53 Merc. When I overhauled the 292 in my ’55, hardened valve seats were used by the machine shop so that lead in gasoline was not a major issue. Lead was removed from gasoline when catalytic converters were introduced. Lead destroyed the chemicals in the converters and rendered them useless. I agree with John in that we don’t use our old cars in extreme conditions and usually “baby” them. Under those conditions I think you are throwing your money away buying lead additives.
