After doing a bit of research, I put together my own fuel blend and have been testing it out for the last week, have got some very good results.
# BP98 (or one of the other high octane ULP) 75%
# Toluene 24%. I bought a 200L drum for $240. Has a RON of 117 on it's own. Totally safe for internal combustion engines esp. at this perecentage. F1 cars in the early 90's used 80% toluene by the way..
# Nitromethane 1%. Cost me $60 for 5L.
Approx total cost is about $1.20L.
By my calculations I'm getting an octane of approx 105, the nitro (a common ingredient in many aftermarket octane boosters) is increasing oxygenation. With the 378 Stroker I'm back on 36deg total advance, all in by 3200rpm, no pinging, but a STACK more torque down low because I'm now running my optimum timing @ 20 deg static, and it pulls like a train at higher revs. Reckon it's even running cooler..
Feels as good a fuel as VP racing fuels ($110 for 20L) and an alternative for those of us having trouble getting AVGAS.
Toluene we use at work to mix with printing ink, the printers have to use gloves and a musk with snorkel its also used in the print wash room and they are not allowed to put plastic in there wash machine.
There will be more carbon shoots produced when burning toluene (compared to petrol). Eventually it will cause block your oxygen sensor. Also it would degrade plastic as well as rubber to your fuel lines as well as seals in your injectors, which may cause your injector to leak after prolonged use.
Swift. Agile. Deadly.

It's not about lightening up TopGhia, you annoyed me yesterday because what you wrote was both factually incorrect and offensive because of your sarcasm.
So to clear things up and explain where I see you as being "narrow minded" since you ask why I think you are being narrow minded...
Toluene is already used in ALL commercial blends of fuel varying from 5% to 20%, more so these days since tetra-ethyl lead got wiped out as an octane booster/knock retardent. So obviously it doesn't do harm to an internal combustion motor. Otherwise every car on the road would have a problem.. So your point #3 is not true. You say it will blow-up your motor? How do you think "motor's blow-up" dude? Wanna be more specific than just "blow-up"? Lets get out of kindie shall we?
As to your other two points, nearly all liquid hydrocarbons dissolve plastic, and ALL of them are volatile and combustable and shouldn't be used near a naked flame or a lighted cigarette. OBVIOUSLY. Whether it's standard petrol or otherwise. So what's your point?
It would be a good idea to do a little reasearch yourself or try things out, before you knock stuff and steer people in the wrong direction. This is a tech forum with the aim of helping people with their cars. Your post was unhelpful on all points.
I am happily and safely getting a lot more out of my driving experience at a reduced cost, and so I am keen to share my findings with others that might also benefit. I also have a University degree in Chemistry, so I am not just sprouting off my mouth like you are. I don't post bullshit.
I did a heap of research on this topic, and also ran Toluene in lower percentages several years ago for a long period of time - for over a year. Never had a problem. So have lots and lots of very street wise Hot Rodders that I have spoken to, some with big money spent on their motors. Do you think they would run the risk of motor damage?
You CAN run up to 40% toluene with no harm to your motor or any of the fuel resistant plastics used in your fuel lines, fuel bowls, injector seals etc. It does very slightly increase the amount of carbon deposits and in percentages over 40%, you need a hot ignition for it to be effective.
If you don't need the octane increase then there is no advantage in running it.
we now have an Australian standard no more than 10% toluene is allowed in petrol and it must be stated at the pump if does contian any toluene. RACV & NRMA say having a high mix of toluene and petrol makes your enginge wear a lot quicker.
quote from senate inquiry.
1.12 Petrol substitution is a type of fraud that not only results in a loss of excise revenue but also may damage the vehicle engines for unsuspecting motorists and distort the petrol market.
has good points also.
1.9 Toluene boosts the octane rating of petrol and in so doing it prevents knocking, which is essentially the detonation of petrol during the power stroke. Knocking is so-called because of the “pinging” sound heard in the engines of cars using petrol of too low an octane rating.
