Title: Anyone here ever use toluene or xylene as a fuel additive
Post by: Greaterthenjake on November 10, 2022, 11:21:08 PM

Trying to find opinions or even best practices in using either. Toluene is already an aromatic so I would think it may not have a huge effect on the fuel system other than adding octane.

     Toluene is already present in many/most fuels, so the typical fuel system componentry should be resilient, but increasing the ratio may, as it is also a solvent, begin to have an effect at some point.   :-\

I had heard of it's use as an easy cheap octane booster. It's a ratio of about 2.5gallons to 5 gallons of 93 should be around 100 octane. No MMT to worry about either. Asking here as there is usually a wealth if knowledge on these things. Xylene I guess is similar but from having used the stuff it eats everything and the smell is just awful.

This has come up on speedtalk and actual engineers and scientists have weighed in.  I suggest you search over there.
