If this fuel is for sale at a gas station that is open to the public it can't legally have lead in it, at any concentration. That is a US law, not a state law. Lead has been banned for sale in a road licensed vehicle since January 1, 1996
It can still be sold for aircraft, off road vehicles, and racing purposes confined to a track.
