Hi there
Has anyone tried toluene as an octane booster? I would like to try it with my high compresion turbo engine see how is fairs. It is used to raise the octane in pump petrol at the refinery, and it was used by the F1 teams in the 1980's, specifically BMW to support the 1500bhp 1500cc engine.
cheers J

Hi there
Excellent! Was it effective? Where did you get yours from? I'm running a 930cc block with an 875cc head, so i have around 10.5:1. Yeah 100 plus would be good, i run 97 octane with millers or castrol to bring it up to 99 (according to the bottle). I'm only running low boost, but i want to ensure that it dosent detonate.
cheers J

to be honest it was in the 80s i actually got it from the chemist !!!!! the guy just asked me what it was for so i told him lucky for me the guy was a car nut into big yankV8s lol in my mad sience theres also outher substances to raise octane ill spout them to ya later the sh1t we were running had 15 to 1 comp !!!!!! didnt last long tho (methanol is good at wording of detonation)

I don't really fancy putting methanol through my fuel system, its very good at rotting most of it! Good detting resistance but a pain in the a*s to use. I'm guessing these bikes were for drag racing? 15:1 is a very high comp to use with a turbo, how did you hold the heads on ;-)

stay clear of methanol its orrible stuff,and i think not road legal.this stuff burns clear without a visible flame or smoke and thew only thing that puts it out is water.indycars run on it and every now and then you'll see a driver or pit crew doing a chicken impression beacuse the methanol is on fire and thats why they throw buckets of water over an indy car after a refuel stop.

Really? I thought conventional wisdom was that using water on a hydrocarbon / petro-chemical fire was A VERY BAD THING, as it just moves it around (the fire can float on top of the water). Sure the water will cool it, but not before it's spread it about a bit. C02 or AFFF would make more sense I'd have thought.

a mate of mine works for bp, as a fuel chemist and he brews his own fuel using tolulene. runs a 1200hp skyline. ill see if i can get in touch with him thru the week .hell be able to shed some light on the subject.

ethanol has been used in petrol in queensland since the early 1930's,I think you have been listening to the propaganda put out by the US (them again !) fuel companies who ran a very succesful scare story a couple of years back about ethanol rots seals etc.... it doesn't. In fact the oil companiers cooked this up so that gullible politicians would insist that the product that the oil companies had made using waste products would be substitiuted.MBTE. It's The worst thing to have been invented.it attaches to water molecules and in doing so has destroyed underground water systems in the US. Shell was fined some horriffic amount of money and instead of copping it on the chin,kept using this stuff and passed the cost of the fines on to the US motorist. It's basicly there to act as an oxygenator so that there is complete combustion of the petrol and thus less exhaust emmisions. Toluene is brilliant stuff to add to fuel as an anti knock ingredient. If you want it in bulk,go to a paint ingredient supplier.It's paint thinners in drag. I have a mate in Oregan who races a 300SEL 6.3 with 13-1 pistons,doing 13 second quaters and has used up to 98% toluene as fuel,then driven home through Portlands crappy traffic.No problems at all. A lot of us 6.3 owners are always trying something different in our fuel and the best thing to come up is not all those expensive octane boosters ,BUT,ATF!. yeah trans fluid!. I put in about 250-500mls every second fill and it's brilliant!.( this is in an engine,that if i blow it up could eat up $40,000 in repairs) You can buy cheap genric ATF which is no good for auto trans but great for fuel!. ;D ;D ;D

Many years ago I changed my driving style to cope with rising fuel prices; I have now reached the stage where I am contemplating keeping my eyes shut in order to lower wind resistance.

during marshals training at brands hatch,we were told that when methanol powered cars crashed we should only use water on them and to cover everything and everybody in the car just to be on the safe side.i thought it odd but there you go! btw meth powered cars must always run an orange dot next to their race number to show that they are meth powered.

It does sound a little odd that, seeing as on most fuels spraying water on the flames is about the stupidest thing you could do, but then again could it be something to do with the water and methanol reacting in such a way that the water and methanol chemically join and become a more stable compound that doesn't burn or react at the temperature methanol burns at or something? Or am I just talking sh*te? ;D ;D

I think a lot of those octane boosters contain Kerosene... or am I wrong... Also, aren't Methanol flames invisible? Or is that something else? Well there you go, looks like I've really cleared that up then! ;D I'm watching this thread with interest... don't really fancy having to tank up with Super every time... additives could be the way forward!

I think the reason that they use water on methanol, is that methanol is water soluble (sp?) and so waters down. Petrol etc are oil based and when water is put on a fire of such a liquid it turns to steam and pulls a lot of fuel into the air making big flames.
How does the ATF thing work? I always thought that putting oils in with fuel drops the knock resistance? Acetone is another great one, i have a friend that runs an austin seven special, 750cc supercharged to 40psi and runs on methanol/acetone/toluol and a touch of nitromethanol!
Next stop the paint suppliers!

Right been to the paint suppliers, and standard cellulose thinners is comprised of toluene (114 octane) xylene (117 octane) and a tiny bit of methanol (no more than 5% so no trouble in the fuel system). It costs £16.50 for 25 liters so is cheaper than petrol! Uh oh i can see my car in a haze of highly volatile chemicals, making people cry as i drive down the high street!
I'm going to fix my car and get some this afternoon and will report back with the results
