Terry and Andrew,
Methol Benzine?
methol benzyne?
Is this what BP are calling it?
AFAIK Methyl Benzene and Toluene are the same thing.
Most octane boosters used to use Methylcyclopentadienyl Manganese
Tricarbonyl (MMT) but I think this now illegal for road use.
This link has some basics on fuel and octane ratings etc

This one is something new to me it deals with optimising fuels physical
properties. http://www.gtatech.com/news_au_articl.html

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).
