I had the ratios wrong. I misread their ad here;

MMT was removed from fuels a long time ago for many reasons, as I'm sure you know. Posted for others.

Ethanol would be a better option I think. Logistics is the main issue and cost, of course.

Currently, there is no 94 octane fuel in the area around Grand Bend, but that should be changing. I've been talking with one of the local gas stations, and they are looking at bringing in a higher octane fuel for the summer. Most likely something in the 94-98 octane range, as the track only carries 100 Octane+ options right now. As I understand they are currently deciding whether it will be drum based or stored in a new tank underground.


I believe the street price is about $40 a can, so "Race Gas" brand is not cheap. But it works. The 91->94 price jump probably equates to about $10 a tank at the station for comparison. The plus here is you could run a ZERO ethanol fuel (which some people like) and still get 94 octane.

Can't do that with Ultra 94 since it's actually more than 10% ethanol.

As for using ethanol as an additive - the problem here is that while it does raise octane it has a much lower energy content per unit volume than gasoline. It is also highly hygroscopic. MMT brings a SHIT PILE of energy to the table, in addition to the octane bump. Our cars are also very sensitive to ethanol - it's the reason our fuel pumps chirp like crickets.


MMT was removed solely due to tree huggers. Anything else you read is more or less a sales pitch.
