Type of fuel required, plus knock 88 t ?

It really isn't an issue of how 'corrosive' toluene and xylene are. In general terms, corrosivity suggests extreme high or low pH's, but since these compounds are pure hydrocarbons - i.e. nothing but carbon and hydrogen, they will not easily loose H+ or OH- ions (those that do are considered 'corrosive'. In fact, OH- wouldn't even exist in a true hydrocarbon because they contain only hydrogen and carbon. No oxygen).

What they are are excellent solvents for mostly hydrocarbon (oil) based solids like clear coat and paint. In fact, I used to use toluene to dissolve and strip pure wax from my skis.

While not corrosive, toluene can be very harmful to latex and other synthetic rubbers. If you dip a latex glove in toluene, it will cause the glove to majorly swell, and it will fall apart pretty easily. These types of chemical reactions are usually dependent on concentration and temperature.

In this case, none of that really matters. Gasoline (octane) is as oil-like, and as much of a hydrocarbon, as xylene or toluene, and would eat up a styrofoam cup (and maybe a latex glove) just as fast. If high octane gas isn't eating up your gaskets or rubber lines, then xylene or toluene won't either - especially over a couple of tanks at 30% or less. I say go for it.

some on remebers there chemistry class lol but if i remember right the owners manual calls for 89 for regular performance and 93 for improved performance but this is at STOCK boost so if you have any thing done to your car spend the extra 30 cent and get the good stuff

one last question whats the highest you can run % wise of this stuff. Is 30% the most or can you go with more? btw this is for my racecar not my supra (though i may add some to it too)

I wouldn't go over 30%...read these links:

As Adjuster said, you can mix in a small amount of tranmission fluid as a lubricant. I have not and have experienced no problems, but I'm also only using 1 gal per tank.

Xylene & Toluene are two solvents (among others) gasoline blenders use to increase octane...it should not show in a tester and does not contain lead.

I use 1 gallon of Xylene (it has higher octane per gallon) per tank...that will increase octane from 91 to about 93. It has the same effect as race gas...it decreases the likelihood of detonation. Be very careful with both Xylene and Toluene...nasty stuff...you don't want to get it on you or your paint

Here's the math to figure octane using either:

(A x gas octane) + (B x 114 or 117) / (A + B) = Octane Value

A = gallons of gas
B = gallons of Toluene or Xylene
114 = octane value of Toluene
117 = octane value of Xylene

So this is just basically a makeshift octane booster? How does this compare to just buying a bottle of octane booster at any autoparts store? Or is it more like using race gas? Just curious.

they used to use this stuff in the turbo indy car's iirc they where boosting 35psi+

 

[supra90turbo]

Yes. Straight Tolulene with a 0 hydrocarbon filler.
Those old turbo indy cars were awesome. Damn the deaths they caused along with GrpB rally...

This is the most informative thread I've read on this subject so far. Good choice bumping this one.

I just went and bought some Tolulene at Menards, to all here in the midwest for 12 bucks a gallon, and damn I didnt think I would notice such a change, this stuff is awsome, thanks to all here on SM for the info. Ricardo:love:
