I know Terry has done a lot of testing with the stuff and it does work from the results. None of them do what the manufacturers claim, but 1.5-2 octane points when adding to 91 octane is believable.

Some good independent lab testing here: http://www.fueltechexperts.com/2008/...which-is-best/

Obviously, I'd run 93 if we had it. Meth also works wonders, but I don't want it on this car. I'm running a whole bunch of straight VP M1 on my other car.
