Not Ranked
Toluene is already used by the refiners, but it's expensive, consequently, they don't use a high percentage of it. MMT is better, but the EPA nixed it because it is not friendly to catalytic converters. Check the contents of contents in octance boosters at your local auto store. I've found that VP's octane booster works fine, doesn't require rejetting or timing changes and prevents detonation and runon. And it helps keep the goodies in the combustion chamber clean.
