Terry,
Yeh methol benzyne is another name for toluene.I think that the bp 100 uses
extra lead to get there octane like avgas.I use ultimate98 with 25 percent
toluene when i run high boost which gives you around 102-104 octane.I have also
run C16 but would need a different turbo to get the full benefit (117 octane).
