Be happy you can still get it over the counter (OTC).

Gentlemen, DEA does not cover these chemicals. You'd probably have ATF and Homeland Security on your butts.

They don't cover electricity either, but you use too much they may give you a visit!

Don't worry about that. Just have some cookies and milk ready to give to the DEA, after they kick your doors in! :lol

BTW, I read similar articles to what John B posted. Note that toluene is the most cost effective, but is much higher in price than $2.50/gal. When I check it was more like $8/gal in a 55 gal drum special order from the paint store. I don't know if you get on the DEA list, but if you pay in cash and cover up your license plate, you are good to go. :rofl Note you have to be careful not to spill the stuff, as I have heard that it can damage your paint. Toluene is harder to vaporize, so depending on the temperatures you drive in, adding too much will cause hard starting problems. 30% is considered max, and that is for warm weather use. Also note that you are diluting out the additive package in the gasoline the more you add. That cannot be good for the car.


Guys, are you aware that Sunoco and others solved your problem years ago....it's called "race gas". You should check it out.:biggrin

Yes, race gas would be better, but it is not available in all area, however paint stores usually are. I haven't tried either yet, just the low 91 octane CA gas. I wonder why other states have 92 and 93 at regular stations but we are stuck with only 91 in CA.

I use NOS race formula octane booster since Shell kindly took away their 100 RON product from our market, leaving us with 98RON (which is essentially 94PON). It does the trick in providing a margin of comfort in octane level for both my GT and Cobra.
