Just out of curiosity, does anyone know if it is ilegal to run straight toluene? I know that it is basically whats in Octane Boost, but in pure form it burns nearly 100% clean, doesnt ping and has a ron of about 110. I know its exy too,well, $1/litre but just wondering.
Cheers

Toluene is very bad for peoples health?

basically Toluene is Methyl-Benzene, and Benzene is a potent carcinogen.

off topic a bit, but here's an interesting MSDS for "Carby Cleaner"
http://www.wurth.com.au/msds/1893_100.htm

Quote:

TOLUENE
ES TWA: 100 ppm, 377 mg/m3; STEL: 150 ppm, 565 mg/m3 (Under review)
PROPOSED CHANGE
ES TWA 50 ppm, 188 mg/m3 SKIN
TLV TWA: 50 ppm, 188 mg/m3 SKIN A4
OES TWA: 50 ppm, 191 mg/m3; STEL: 150 ppm, 574 mg/m3 SKIN
MAK value: 50 ppm, 190 mg/m3
MAK Category II Peak Limitation: For substances with systemic effects
and with a half-life in humans ranging from two hours to shift-length.
Allows excursions of 5 times the MAK value, for 30 minutes (on average),
twice per shift.
MAK Group C: There is no reason to fear risk of damage to the developing
embryo when MAK and BAT values are observed.
IDLH Level: 500 ppm
Odour Threshold Value: 0.16-6.7 (detection), 1.9-69 (recognition)
NOTE: Detector tubes measuring in excess of 5 ppm, are available.
Exposure limits with "skin" notation indicate that vapour and liquid may be
absorbed through intact skin. Absorption by skin may readily exceed vapour
inhalation exposure. Symptoms for skin absorption are the same as for
inhalation. Contact with eyes and mucous membranes may also contribute to
overall exposure and may also invalidate the exposure standard.
High concentrations of toluene in the air produce depression of the
central nervous system (CNS) in humans. Intentional toluene exposure
(glue-sniffing) at maternally-intoxicating concentration has also produced
birth defects. Foetotoxicity appears at levels associated with CNS
narcosis and probably occurs only in those with chronic toluene-induced
kidney failure. Exposure at or below the recommended TLV-TWA is thought
to prevent transient headache and irritation, to provide a measure of
safety for possible disturbances to human reproduction, the prevention of
reductions in cognitive responses reported amongst humans inhaling
greater than 40 ppm, and the significant risks of hepatotoxic, behavioural
and nervous system effects (including impaired reaction time and
incoordination). Although toluene/ethanol interactions are well
recognised, the degree of protection afforded by the TLV-TWA among
drinkers is not known.

i don't know how many cubic metres of skin you have, but 200mg/cubic metre is only 0.2mls!!!!! probably not even one drop!!

remember those stories of mechanics washing grease off themselves with toluene? and dying over the next day or two?

and to anyone using 'octane boosters' be very careful when draining or working with tainted petrol.

to anyone using carby cleaner with bare hands and no respirator... ummm... get gloves and respirator Wink

ps, anyone seen how much hydroflouric acid (HF) is in some "metal brightners" and "mag wheel cleaners" ?? enough to make your fingers turn black, die, and drop off Wink
