I use Max Lead a tetraethyl lead additive I buy for 45.00 a gallon. I add 1 ounce for every gallon of gas and it raises the octane to just over 101. Premium 93 octane is currently selling for 2.06 a gallon and add .35 cents for each ounce of Max Lead, that gives me 101 octane gas with lead in it for 2.41 per gallon.
