Thanks mehoff, yeah..I've read that a bunch of times. The problem is with finding the virgin stuff. (perhaps I had the virgin stuff before via the Xylene I bought from Sherwin Williams and it was just a bad batch? "pure" but 10% benzene? ...or maybe it was just that my knock sensor was bad at the time...it was diagnosed as a problem back in July when it was dyno tuned). When I added the Xylene that had 10% benzene from Sherwin Williams I saw more KR than ever before and suddenly lean O2 readings (around 830 mv's) ......coincidence maybe?

Well, I guess I just have to shop around even more. "1993lt1" let me know what you've got and when you'll be around....thanks.

 

Got any airports around there?Years ago I used to buy av-gas at a small airport.

 

I called sunnyside and got A M.S.D. sheet. Xylene 75 to90 % Ethyl benzene 10% to 25% .But if you want some I wheel sale you some at cost. I wheel be in Huntington o2/16/03 and Charleston 04/01/03.

 

You can get at some paint stores... What i would do is go to one of the older paint stores in your area or older hardware stores and make sure you got 100% Think last time i did the math its a 1-3 mix to get you 100 octane or so... I just don't know the stores in your area so can't tell ya who is gonna have and who isn't as most are putting in mixxes now from what i have seen.

The fuel companies do sell the fuel in 5, 15, 25 gallon tanks here but when i have tried to contact fuel companies via email i have not gotten a reply.

How much difference does this stuff actually make in performance?

 

av gas has serious lead in it so be warned in case you guys didn't know. The low lead stuff is still insane high with lead.

The octane can make you alot more power reasoning is you can run more cyl pressure without detonation. So meaning you can run more timing or more boost or whatever.
