Welcome to the TR support group and 12 step program! Please bring

I'll try to handle this one though probably the engineers on the list
might have a comment or two if I should stray from the facts. Lead
additives are just that. Tetra Ethyl Lead is a protectant that
primarily cushions the valves and seats with a microcopic cushion
of lead thus proloning their life (in theory... though there are folks
who have used unleaded fuel since God was a pup and swear to never
having any trouble). Octane boost on the other hand is a different
story. Road & Track had an article a couple years back about the
relative effects of various Octane boosters... You might want to look
it up. If memory serves there were differences in products but
overall the benefit of all products was negligible to minimal .
Having said that,I admit to using Octane boost on my somewhat modified
TR4. I have had the best result (performance wise) with +104 Octane
boost.
The best performance I have ever experienced was to mix a tank of 93
octane and Turbo Blue racing fuel 50/50 gas to racing fuel. At
>$4 per gallon it's something I don't do often. Besides it's not
generally available for street use.
