xylene...Wear gloves. I use a pump to put it in. Dont try to pour it because if it splashes anywhere your f@#!. It does make the exhaust smell so try not to idle in one place too long. After about 40 gallons of xylene you could have bought a alky kit. Xylene is about 50$ for 5 gallons. At least in the SF bay area.
It also makes the skin around your eyes very sticky, when you splash it in them.
Moral: Eye protection.
I pour it into a can with a couple gallons of gas in it, then dump that into the tank.
Not as nasty as straight xylene.
I've never seen a concentration greater than 20% do significant good, in terms of knock reduction.
Years ago, the F1 guys tried to burn this stuff pure... the rules people caught on.
