Actually (1) the pump is located near the Bandimere Race 1/4 mile race track. So, it is highly likely it is fresh. Though lead is used in racing fuels it is not used by itself, but mixed with Tetraethyl Lead. So in my example, mixing a small percentage of 100 with 91 to reach a 93 on rare occasions seems insignificant.
