What does a bottle of torco cost? My problem with octane boost additives is they never really tell you exactly what octane boost your going to get with it or they say “up to xxx !!” I say; how, when, where and in what? A lawn mower in Duluth in October?

I've read several articles on octane...my take away is it's pretty fuzzy science (to me). One article praised toluene as a wonder elixir, another chided it because of it burn characteristics (over my little head). I don't recall all the ins and outs but it seemed the “octane boosters” never even made it to the table.

I guess to me it just boils down to is how it compares price wise to a home brew of brand name 100 oct racing fuel and regular name bran pump gas. Both are known entities and the real thing octane wise.

I'm set to up my boost with H2O/methanol injection. For whatever reason this works out to be the equivalent of upping the octane in a round about way. Lot cheaper then 10 bucks a gallon for race fuel.
