Toluene has been used for yeeeeaaars in F1. Or at least it was used years ago. The fuel was capped at a maximum octane rating and a certain amount. They ran up to like 80% toluene in their boosted engines, and they also froze their fuel. It would expand like 50% or something ridiculous like that as it warmed up, providing them with plenty of extra. I love F1 sometimes, sneaky bastards.

Oh, and you can get Toluene at a paint store, maybe even walmart :)

We used it in the 1960s to boost pump fuel.

Yah and they were putting like 30+ psi of boost on it, haha

they also gelled the toluene. cant imagine the fuel pressure needed o inject that stuff..... but they aimed the injectors UPSTREAM, nstead of down like a normal fuel inj'ed car. Guess it has to do with atomizing the gelled fuel

Just to be pedantic about symantics, toluene or xylene are not really additives. They are fuels in their own right, so adding them is a blend, like if you mix regular and race gas.

Tetra ethyl lead is an additive because you only need to add a little.

What does toluene cost for the 5 gallon cans at paint stores?

I was thankful to have read that link. Most octane boosters only give you .18-.2 ron or that much of a full octane number for the good ones and .1 ron for the cheap ones.

So if you get the octane booster from the dollar store and it says it treats 15gallons with a .1 ron increase does that mean you can run four of those bottles to 5 gallons to raise it up 1.2 octane numbers. J/K.

I'll all ways be grateful to have found out just how much of a scam the octane booster industry has been.
If I get around to calling the paint store I'll get a price on some MF Tolene and put it up here.

We have a local oil distributer selling premium regular gasoline 95 octane that smells like they've added a bunch of Tolene. It has more heat energy giving better mpg but seems like it needs more timing in some spots of the map.

That is what toluene will do.

It can also be bought in bulk from chemical supply houses or industrial grade solvent vendors or even oil companies.

i suggest anyone looking to use toluene or xylene price it out, then price out C16 or any other high octane fuel.

you will notice that race fuels are less expensive. usually by a lot.


i once got my hands on a 5L jug of toluene for free. that was the only reason i messed with it, otherwise it was way too expensive.

around here xylene is around $16 for 4L.

I have not bought toluene for over 20 years, but back then it was a little more expensive than normal super grade pump fuel. It is very likely that C16 contains a lot, like maybe 50% toluene. At $4.00 per litre I would not buy it.

You just need to do your sums as to what it costs vs alternative ways to get the octane you require. Here it was used as a substitute because it was cheaper than unleaded petrol due to tax avoidance, however current prices seem a lot more expensive than unleaded.

Where I work we have hundreds of gallons of Toluene, Xylene, Heptane, and Iso. I run Iso to help pass emissions.
