Just a note regarding low octane alco-free mo gas.
As good an octane booster as alcohol is, it ain't nothin compared to tetraethyl
lead.
A previous fill of 100LL, burned down to 30% of capacity, when filled with 92RON
will test higher than the 95RON with alcohol tests.

PS This was knowledge won during the dark days of the '80s when we found that
a mix of leaded regular and regulated unleaded gave a better AKI than either on
our street rods. And 100LL has a lot more lead than leadad regular. Staved
off extinction for a few years.
