Octane boost - home made race gas
I found the following about using Toluene in Gas to increase the Octane levels. I just bought a 5 gallon can for $48. I put it in my lawn mower and had not problems. I will be trying it in my car soon to see if butt dino says anything. I do not think it will but I will also see if by racing someone if I can pull harder harder away form him. I will try a mix that will boost octane to 95 and see what happens for like one or 2 gallons of gas.
Let me know what you think about this.

I don't know? Accordinding to the follow up posts it's crap and expensive crap at that
but let us know how it work's cause down here in the AZ you can only get 91 octane unless you visit an airport
I think that the other guy that posted that it was crap us not right because in the document you can read this.
Toluene is a pure hydrocarbon (C7H8). i.e. it contains only hydrogen and carbon atoms. It belongs to a particular category of hydrocarbons called aromatic hydrocarbons. Complete combustion of toluene yields CO2 and H2O. This fact ensures that the entire emission control system such as the catalyst and oxygen sensor of your car is unaffected. There are no metallic compounds (lead, magnesium etc), no nitro compounds and no oxygen atoms in toluene. It is made up of exactly the same ingredients as ordinary gasoline. In fact it is one of the main ingredients of gasoline.
Toluene has a RON octane rating of 121 and a MON rating of 107, leading to a (R+M)/2 rating of 114. (R+M)/2 is how ordinary fuels are rated in the US. Note that toluene has a sensitivity rating of 121-107=14. This compares favorably with alcohols which have sensitivities in the 20-30 range. The more sensitive a fuel is the more its performance degrades under load. Toluene's low sensitivity means that it is an excellent fuel for a heavily loaded engine.
Toluene is denser than ordinary gasoline (0.87 g/mL vs. 0.72-0.74) and contains more energy per unit volume. Thus combustion of toluene leads to more energy being liberated and thus more power generated. This is in contrast to oxygenated octane boosters like ethanol or MTBE which contain less energy per unit volume compared to gasoline. The higher heating value of toluene also means that the exhaust gases contain more kinetic energy, which in turn means that there is more energy to drive turbocharger vanes. In practical terms this is experienced as a faster onset of turbo boost.
Chevron's published composition of 100 octane aviation fuel shows that toluene comprises up to 14% alone and is the predominant aromatic hydrocarbon. Unfortunately composition specifications for automotive gasoline is harder to pin down due to constantly changing requirements.
Chevron's web site also describes the problems of ethanol being used in gasoline.
MTBE was heavily touted as a clean additive several years ago, and became a key ingredient in reformulated gasoline that is sold in California. But recently new studies arose that showed that MTBE was far more toxic than previously imagined. Organizations such as oxybusters have formed around the country to eliminate the use of MTBE in gasoline and several states, including California have passed new laws to eventually outlaw MTBE.

Thanks for the education on toluene. I was just pointing out that others opinions said it was crap. I don't alway's believe others op. if I did I wouldn't be driving an SS and that would have been
I'd still like to see what you experience, and I may try it myself

i can get 101 at the pump here in north phoenix , so you aint looking hard enough

I can also get 110 at local 76 but it contains lead and that is not good for the cat and 02 sensors. I am still looking for other gas stations that sell 92 and up but this is only if I go to track and again I do not know if it contains lead.
From the resurch that I have done so far I found that these are used in gas to incress octain rattings.
ethonal - ok to use
MTBE - ok to use
Toluene - investigating
Methonal - not good for Cobalt SS corodes injectors and feul lines
MMT - same as Methonal
Lead - not good also
Just put 1 gallon of Toluene in tank and did not have any advers affects. Car seems to run fine. I can not tell if any inprovment put bumping octain to 93 would not really show unless on a dyno. I have also tryed it in a 80 somthing datson truck and it ran smother.
I will try a 2 gallons at next tank to see what happens.

Check this article out by Car & Driver. They tooks some cars including an M3, and ran regular and premium gas in them. Some cars required premium (M3, Saab 9-5 Turbo), while others did not. They dyno the cars before and after, and track test them to see any differences. Interesting read.

I agree with the artical in that I will see vary little gains but since I can not get any race gas and primium is only 92 in oregon you can see why I am looking at Toluene. I think that I will gain a little by useing it but not much. I just am looking for ways to increes octain for the race day. If I can shave a teth or so off of my times then that this is cool. I would like to try 100 octain mix and see if any inprovment. I think that with the cobalt being SC it will help alot. I just wish I had a dyno to tell me how much is gained. Anyway thainks for the artical.
No prob, I am just glad I remembered it, 'cause it's older than I would have guessed! I'm sure you'd notice a difference with 100 octane.
If you really wan't to go fast, youshould think about getting the stage 1 and 2 kits when they come out. A 270+ HP Balt would be sweet!!!!

this guy i know used to make his own 95 octane race fuel for his car. he would put 1 lbs. of moth ***** in 8 gallons of 87 unleaded fuel for 2 weeks. and i guess its a higher octane when all said and done. anybody else ever hear of this?
Hear is a discription of Mothballs witch is made of naphthalene. It is a hydocarban so it is the same as gas not as flamable though. I would suspect that it would help increes octain but not sure. Since it will profibit knocking do to it not being as flamable as regular gas.
Naphthalene
Description
Naphthalene (CAS #91-20-3) is a white solid with a strong smell; is also called mothballs, moth flakes, white tar, and tar camphor. Naphthalene is a natural component of fossil fuels such as petroleum and coal; it is also formed when natural products such as wood or tobacco are burned. The principal use for naphthalene is as an intermediate in the production of phthalic anhydride, which is used as an intermediate in the production of phthalate plasticizers, resins, phthaleins, dyes, pharmaceuticals, insect repellents, and other materials; other products made from naphthalene are moth repellents, in the form of mothballs or crystals, and toilet and diaper pail deodorant blocks. Naphthalene is also used for making leather tanning agents, and the insecticide carbaryl.
There are two common compounds related to naphthalene: 1-methylnaphthalene (C11H10, CAS #90-12-0), also called alpha-methylnaphthalene; and 2- ethylnaphthalene (C11H10, CAS #91-57-6), called beta-methylnaphthalene.
Chemical properties
Naphthalene evaporates easily; when its vapors are mixed with air, the mixture can burn easily. It is soluble in benzene, alcohol, ether, and acetone; it is soluble in water at 20 degrees C. It is a moderate fire hazard when exposed to heat or flame; it reacts with oxidizing materials and chromium anhydride. It is a moderate explosion hazard, in the form of dust, when exposed to heat or flame.
Synonyms for naphthalene are naphthalin, naphthaline, tar camphor, white tar, NCI-C52904, albocarbon, and naphthene.
Identification
Chemical Name: Naphthalene, Crude
Regulatory Name: Naphthalene
Formula: (C10H8)
DOT Label: Flammable solid

Not a good Idea according to this artical:

Toluene in alreay in gas so it should not harm anything even warrent. See this page:
