here are some common ways to boost your octane using off the shelf products.

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*, ie. 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 ontent 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 = techron ;)

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.
