He is an idiot. The lead will ruin the O2 sensors in short order. I've seen an O2 killed at the track in one session when 5 gal of leaded gas was accidentally popured in.
BMW and Porsche, Ferrarri all reccomend Techron be run 1 time between each oil change prefferably the last tank or so of fuel before you change the oil.
I've done this for years and when I've torn down the engines they are nice and clean in the piston head areas prone to carbon.
