Go to sportcompact cars website. They did an article about octane boosters and the nos racing booster did boost octane on california crap tractor gas. Very good article.



The NOS Off Road version (maximum MMT allowed) added a full 2 octane rating to the 91 octane tractor piss. It was proven to be even better then using Toluene as a home brew octane booster; well for the money any way. It took 1.5-2 gallons of Toluene ($15-19) to match the $10 bottle of NOS Off Road.

The other aromatic and solvent types of octane booster ranged from negligible to ~1 octane.
Quality amounts of MMT is the way to go. However it does transfer into your oil and can eventually foul O2 sensors. (hence the off road "legalize" in the warning)




Yes, that's the article I'm referring to. I thought they were able to make 93 octane out of it but I didn't want to quote it. lol
