Octane booster - is there something available?

Acetone - but get the % right!! Was an old racer's trick. They called it 'doping'. Is banned.

+1 on the Acetone.. but it really doesnt add Octane .. all it does is boost the energy in a by making your fuel burn faster and hotter .. improving flame fronts and thereby increasing power and fuel mileage

and MSTRS is correct .. carefull with the mix .. a few shotglasses full is all you'll need on a 20 ltr tank ...


i use it regularly..

[MSTRS:Me]

And you tried to tell us it was what you were eating that made your exhaust smell like that!!

Increasing Octane rating is about being able to run higher compression and more advanced timing. It doesnt add 'energy' to the fuel but makes the fuel combustion more controlled and less likely to pre-ignite.

Unless you tune your engine to take advantage of higher octane you will not see much performance increase. Likewise if you have an older engine with low compression it is likely you only need a lead replacement additive to protect your valves.
Most modern engines have knock sensors and the ECU will retard the ignition if the fuel octate is too low (among many other factors) to prevent an incorrect or damaging ignition burn.

yea ... i think my engine is 'tuned' enough ...

No not really - most commercially available octane boosters only raise the octane by 0.1-0.7 so pretty ineffectual really.
Toluene does work, but I'm pretty sure you can't buy it now as it's nasty stuff.
There may be something else but I'm not aware of it, in the meantime you might find this interesting reading (it's a little slow to load, so be patient)

"Solvent Supplies" ........sounds dodgy....
