Octane Booster Formula's!

[5th_Ave_Sleeper]

I have downloaded these from somwher a while back I cant remember if I posted them before or not, but what the hey here they are again. These are not gospel! I have not tried any of the yet, so use at your own risk!!! Most of the solvents can be bought at any local paint supply store, i.e. Sherman williams, pittsburg paint etc.

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):
o 100 oz of toluene for octane boost
o 25 oz of mineral spirits (cleaning agent)
o 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.

Nos/permatex has a new one out that adds 7 octane points to 60 litres. I think its about $17 Canadian.

I bought some for my buddy to try in his 13:1 rallye car.(Sorry, but it's a german car, not a mopar)

[rumblefish360]

Does anybody have a Gallon vs. litter conversion equasion?

[dave571]

I don't know the equation man.

I'm pretty sure that 4 litres is about the same as a us gallon. while a canadian Gallon is closer to 5.

That's pretty close. Gives you an idea anyway

[cuda66273]

That sample formula ........ works....

Not in my motor but I know that it works.....

[72Challenger]

1 U.S. gallon = 3.785 liters
1 Imperial gallon = 4.226 liters

I might sound like an idiot to ask this, but in the formulas for the boosters, what does R+M/2 mean? Also, is this stuff legal to make?

[John Kunkel]

Two popular ways of measuring octane are the Research method and the Motor method.
Adding the two octane numbers and dividing by two gives the average of the two. (R+M/2)

[5th_Ave_Sleeper]

Yes, its leagal to make, just do it in a well ventilated area, and dont smoke while mixing chemicals.
Remember now, octane boosters wont do you any good if your not running a high compression ratio. Putting this stuff in a stock motorwill yeild little or no results. You must have @ 10.5:1 compression or higher to benifit from the concoctions.
This is just a cheaper way than buying the stuff "off the shelf"

Ever heard of mothballs in gas tank?

Guys claim hp gains. I think they're nuts...

[70Ted]

any1 tried this stuff?

What do you think the octane rating would be required for 11.5 aluminum head engine?

Yeah I think that they are nuts too. Moth balls can recrystalize in the fuel system and mess things up.

I run xylene and/or toluene in my Gran Coupe. The idle seemed to really smooth out and throttle response might be a tad bit better.
Some will say there is no difference. I'd rather add toluene than pay for race gas.

Here is what I did...
I added 6 gallons toluene to my 18 gallon tank (when almost empty). I then topped off the tank with 12 gallons of Sunoco 94.
This fuel mix ends up being around 100 octane.

The engine hasn't detonated so I gues I'm OK. I was leary when I first read about this so I started by adding a gallon here and a couple gallons there just to see if there would be a problem.

Here is a site with some FAQs on toluene as an additive for octane boost. It also explains the (R+M)/2 method of calculatin octane.

And here is a link I found to 5th Ave's info.

When I bought toluene a couple months ago and it was going for $7.45/gallon.

[Tim_K]

If toluene costs $7-8 a gallon, I'd rather just buy Cam 2 100 octane unleaded locally for $4 a gallon and not worry about some wild concoction screwing up the engine. I think I can get Turbo Blue 115 octane leaded for about the same price if I drive 20 miles for it.

I hope you guys are wearing rebreather masks and rubber gloves. All this stuff is highly carcinogenic. Organic molecules like this are considered primary causes of leukemia and other lymphatic cancers.

Tuolene especially is nasty. It may save you a few bucks, but pouring from the can is MUCH safer.

[John Kunkel]

It's been a few years (yea right) since I took high school chemistry but I wonder, do all of the recommended ingrediants blend with fuel without a catalyst?
In the case of methanol/ethanol, it seems to me that the slightest amount of water in the base fuel would cause some of the alcohol to drop out of suspension.
Any chemistry majors?

[Tool]

I was a chem major.
Alcohols are misible in water. They are stable and won't drop out of solution. Check out the bottle of rubbing alcohol in your medicine cabinet. It's 70% isopropyl alcohol / 30% water and this solution is uniform.

I wear laytex or nitrile gloves when handling solvents like toluene. Act responsibly and toluene isn't anymore dangerous that gasoline.

I've heard about putting moth balls in the gas tank. I don't think that they actually raise octane. They dissolve in gasoline but I have heard that the moth balls can recrystalize in the fuel system and cause blockages in the carb.
