Another recipe for race gas!

my buddy told me that if you mix 3 mothballs to a full tank of gas, it will boost your octane level. Someone try this out and tell me how it goes for them.
Have fun,
mike

"The legend of mothballs as an octane enhancer arose well before WWII when
naphthalene was used as the active ingredient. Today, the majority of
mothballs use para-dichlorobenzene in place of naphthalene, so choose
carefully if you wish to experiment :-). There have been some concerns about
the toxicity of para-dichlorobenzene, and naphthalene mothballs have again
become popular. In the 1920s, typical gasoline octane ratings were 40-60
[11], and during the 1930s and 40s, the ratings increased by approximately 20
units as alkyl leads and improved refining processes became widespread [12].

Naphthalene has a blending motor octane number of 90 [52], so the addition of
a significant amount of mothballs could increase the octane, and they were
soluble in gasoline. The amount usually required to appreciably increase the
octane also had some adverse effects. The most obvious was due to the high
melting point ( 80C ), when the fuel evaporated the naphthalene would
precipitate out, blocking jets and filters. With modern gasolines,
naphthalene is more likely to reduce the octane rating, and the amount
required for low octane fuels will also create operational and emissions
problems. "


quoted from http://www.faqs.org/faqs/autos/gasoline-faq/part3/

And btw, if anyone does a little more research and find that "mothballs were originally made from camphor ( C10H16O, [76-22-2], MP 176C,
BP 204C ), or naphthalene ( C10H8, [91-20-3], MP 82C, BP 218C ),
but para-dichlorobenzene ( C6H4Cl2, [106-46-7], MP 55C, BP 173C ), became
cheaply available as an unwanted by-product of ortho-dichlorobenzene
production, and thus became the most common active ingredient. However
para-dichlorobenzene is also a suspected carcinogen, and naphthalene
has again become a common active ingredient."

so even though mothballs may be naphthalene again...they wont help you out.

besides naphthalene there is
Toluene: 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. It can be purchased for less than $3/gal at chemical supply houses or paint stores.

Xylene: Similar to Toluene. Usually mixed with Toluene and advertised as *race formula.
http://www.state.me.us/dep/air/beam/.../xylene_fs.htm

Methyl-tertiary-butyl-ether (MTBE): 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.
http://www.enzymetech.com/applicatio...mtbe_facts.htm

Methanol or Ethanol: 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.

Isopropyl Alcohol and Tertiary Butyl Alcohol: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol

Yeah my buddy told me to mix a cup of sugar with one tank of gas, why don't you guys try that out and let me know what happens.
