[QUOTE="anvrsy red vert, post: 3582314, member: 19352"] The leaded gas will ruin the O2 sensors!! He is correct. Pay the extra for the unleaded race gas. BTW, lead is added to the gas to increase octane and act as a lubricant for the valves and seats. The old time motor/head combo's used cast iron seats which weren't hardened and cast iron valves which needed the lead as a lube for reduced valve seat wear. Besides not having the lead, the other properties of unleaded race gas are about the same-----burning speed, latent heat of evaporation (cooling effect), specific gravity and octane. [/QUOTE]
