Homebrew Gasoline Octane Boosters
------------------------------------------------------------------------
Editor's note: I would NOT suggest that a person use the
following fuel
mixtures without considering the detrimental effects on your
engine,
vital engine components (O2 sensor, etc), and other potential
damage.
That said, the information is interesting.

Formula #1 - Toulene
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 Toulene. 12-16 ounces will only raise
octane 2-3
*points*, i.e. from 92 to 92.3. Usually mixed with Toulene 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 toulene 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
toulene 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.
