Rusty, I'm not debating the merits of the Vitameter, I don't really know anything about it. But unless you want your engine compartment gussied up with non-authentic but period-correct gadgets, I'd think it's a lot easier, if you have a borderline preignition condition and don't want to retard the spark a bit, to just add some tetraethyl lead. Easy enough to buy, Jack Podell is the major source and ships everywhere. But for the vast majority of owners, it's really not necessary. But if you use it, there are toxicity issues, be sure to wear impervious gloves, don't breath the vapors, and wash up thoroughly. His TEL is a mixture in gasoline, normal treatment is about a quart per tankful of gas.
