I got this off clubwrx and thought it might be usefull.

Formula #1 - Toluene
R+M/2.........114
Cost...........$2.50/gal
Mixtures with 92 Octane Premium
10%...........94.2 Octane
20%...........96.4 Octane
30%...........98.6 Octane
Notes: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $3/gal at chemical supply houses or paint stores.

Formula #2 - Xylene
R+M/2.........117
Cost...........$2.75/gal
Mixtures with 92 Octane Premium
10%...........94.5 Octane
20%...........97.0 Octane
30%...........99.5 Octane
Notes: Similar to Toluene. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Usually mixed with Toluene and advertised as *race formula*.

Formula #3 - Methyl-tertiary-butyl-ether (MTBE)
R+M/2.........118
Cost...........$3.50/gal
Mixtures with 92 Octane Premium
10%...........94.6 Octane
20%...........97.2 Octane
30%...........99.8 Octane
Notes: Oxygenate. Very common in octane booster products. Has lower BTU content than toluene or xylene, but oxygenate effect makes the gasoline burn better and produce more energy.

Formula #4 - Methanol or Ethanol
R+M/2.........101
Cost...........$0.60 - $1.75/gal
Mixtures with 92 Octane Premium
10%...........94.3 Octane (Methanol)
10%...........94.7 Octane (Ethanol)
20%...........Not Recommended
Notes: Methanol is wood alcohol. Ethanol is grain alcohol and found in Gasohol in 10% ratios. Both alcohols are mildly corrosive and will eat gas tank linings, rubber and aluminum if used in excessive ratios. Main ingredient in "Gas Dryers", combine with water.

Formula #5 - Isopropyl Alcohol and Tertiary Butyl Alcohol
R+M/2.........101
Cost...........$0.60-$1.50/gal
Mixtures with 92 Octane Premium
10%...........94.5 Octane
20%...........Not Recommended
30%...........Not Recommended

Notes: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol.

Sample Mixture
To make your own octane booster, it is easiest to make up a large batch, and then bottle it up in "dosage-size" uses.
Below is the basic formula of one of the popular octane booster products. To make eight 16 ounce bottles (128 oz = 1 gal):

100 oz of toluene for octane boost
25 oz of mineral spirits (cleaning agent)
3 oz of transmission fluid (lubricating agent)
This product is advertised as "octane booster with cleaning agent *and* lubricating agent!". Diesel fuel or kerosene can be substituted for mineral spirits and light turbine oil can be substituted for transmission fluid. Color can be added with petroleum dyes.

so does anybody do their own octane booster since sacramento gas sucks with the exception of one station on marconi & watt that actually has 102 IIRC.

 

Nah, I just use tEh nawZ!11 Especially on your mom.

 

Who else wants to take bets on how long it takes him to blow himself up?

 

my mom doesnt take nawz. God what is wrong with you. she only takes prescription topnotch's dad.

 

Try some topnotch then go to the track.

Someone remind me to get my camara out. It will be a good owned pic

 

sheesh tough crowd. i thought people would want to know how to make your own octane booster that actually works.

so i go from posting usefull information to being bandwagoned by the e-thugs.


makes me feel right at home

 

You must be new here.
Welcome to SRIC

enjoy your stay

 

enjoy my stay? watch you talkin bout?

i aint leavin. im here for good.

 

Here's an idea:
Mix products that were never intended for a fuel system (Toluene) into your fuel system and wait for your car to self-destruct.

Just go buy some 100 octane and mix it in if you want > 91 octane. You're running a huge risk by going with products that could potentially eat your fuel system apart. While the Toluene might save you a couple of bucks, it will cost you much more in the long run.

 

wow, i wonder if i should go over to clubwrx and tell those guys. although the users are the big time posters over there. instead of postwhoring useless crap like soggy, they actually contribute to the community and say that their cars run stronger and are virtually knock free.

 

i believe this has been brought up before. the chemicals you have listed may or may not cause damage to the rubber fuel lines. if such damage were to occur, hilarity would definitely not ensue.

egan's been around the block a few times (just ask ed).

 

haha outch. Someone's getting a little "tiffed"

Clubwrx is waiting for you....

Wait, I think I might have brought you over from club wrx..

hmmm

 

clubwrx is cool too

 

"tiffed" no, but dissappointed with what i thought may be a good solution to sacs gas problem . soggy you should know by now how i roll. i have never once gotten upset, mad, or e-thugged anyone on the forum. like you said, this is the SRIC. what i said about you was more towards how you always tell me to not derail a thread. although i dont know how that is possible because i havent done such a thing.

and i dont doubt Egan one bit. i take his advice very seriously. Egan is the man i go to before S-S when i have problems. he has helped me out before and i thank him for that.

clubwrx is ok but not as cool as i-club. over there everybody is too strung up. you say something about their mom and they start to e-thug.

 

Why, that mixter was topnotch! (smoke bellowing in the background)
