Xylene result
 

Took emission again today and passed like nothing had ever been wrong.

Last test I was getting a 270 something HC ppm and 2.12 CO% at idle, which failed me.

Today I got 134 HC and 0.12 CO%. :D

CO2 is unchanged and 02 seems to have increased quite a bit. They kept my old report so I forget the numbers.

Absolutely nothing on the car has been changed but I ran through a tank of xylene (Xylol - 1 gallon) on Chevron 90 and was 95 miles into a fresh tank.

Apparent result: better combustion. Mileage seems to have increased substantially as well regardless of aggressive throttling.

Just an observation.

Crap i totally forgot all about that....can i get some from home depot?

Xylene is supposedly safer than toulene right?? (sorry if I mispelled something)

Xylene doesn't evaporate as fast. That's all I can say.

Xylene? as in paint thinner?

Toluene is the correct spelling.

Todd

Affirmative. A paint supply store may have better prices on Xylene since Home Deptots and other hardware stores alike charge a little bit more for convienience.

If I remember correctly you should be able to buy a gallon for about $10.

I also wouldn't recomend running it in every tank.

Yea only do it once in a while! Not every tank!

and what exactly does it do?

I've never heard of this before....

Its supposed to be one of the best ways to clean the injectors and get great performance and increased throttle response. Many of our members have used it with great results. Do a search you will find the thread with the info...im just too lazy :p

I knew there'd be at least one spelling bee champion on here :D

I just read info at the USMB.net site (that was taken from another site) that indicated that Toluene is just an octane booster, not an injector cleaner. Since you got the results you did, guess I may as well try it myself to see. This is what I read at the USMB.net site *Long* --->

"The main ingredient in Octane Boosters is often Toluene (114 octane). The clever thing is that by packaging it in 6oz. containers and using the words Octane Booster, you can magically turn a $3.99 gallon of Toluene into an $85 a gallon gasoline supplement.

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: 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.

Toulene
R+M/2...114
Cost...$4.00/gal
Mixtures with 91 Octane Premium
10%...93.3 Octane
20%...96.0 Octane
30%...97.9 Octane

You can make your own by combining Toluene with Kerosene in a 6:1 ratio and gain approx. 1.1 octane (RON) by adding 1 gal. to a 20 gal. tank of gas. You can buy Toluene in 1 gal. or up to 55 gal. from a Sherman Williams Paint store. Care need be taken when mixing it and storing it. Octane ratings can be very easily calculated by simple averaging. For example, the tank of an Esprit is 21.0 gallons. Filling it with 20 gallons of 91 octane and 1 gallon of toluene (114 octane) will yield a fuel mix of:

(20.0 * 91) + (1 * 114) / 21.0 = 92.09"

:D

I'm not a spelling bee champ, but I did use toluene in one of my former jobs to evaluate the residual stress levels of various polycarbonte materials when submitted to a constant strain.

I used toluene when I worked at a printing press..used to clean the presses and such..made me higher than a kite too :D seriously that job was harsh..had to sign forms of knowledge of use of materials known to cause cancer...good times
