I always understood that lead as an additive was not widely introduced until the late 30's as an "anti-knock" solution to find a simple way of upping the Octane rating. So that Austin Sevens (and virtually all pre-war engines, other than "racers!") will run happily on the Unleaded fuel they for which they were designed. Mind you I do wonder about some of the evil witches' brew of additives that go into modern unleaded ( E- numbers anyone!).
