Default It adds linearly :-P

assume a 16 gallon tank.

14 gallons of 91
2 gallons of 114
Gives you...

((14*91)+(2*114)) / 16 = 93.875 octane :-)

Default Toluene is very dense and resists combustion at cold temps

I would not recommend running it in the winter months as it settles at the bottom of your tank and you may have difficulties starting the car.

Default Some more information about Toulene, Xylene, etc.

Got this from Vettnet.

Hope this helps. Cheers.

Initial............100

10%............150

Final...........240



And from Rich Lassitter's article in the GS Xtra ... how to mix your own brew:



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.



How to make your own octane booster (this 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.



I'll only add one comment regarding using methanol. In a word, don't.

It attacks zinc and magnesium very rapidly. Guess what is in carburators

and other fuel system parts.

Default When you just can't get any race gas you gotta make your own!
