MMT Degradation

Has anyone had problems with fuel additives containing MMT degrading or volatizing over time? I have a very noticeable performance difference from the beginning and end of a tank of gas. I'm three days into my last fill up and now I'm starting to get what feels like a misfire at high rpms. I goes away and the car runs top notch when I put in fresh fuel and octane boost. Anyone recommend the most effective over the counter?

Re: MMT Degradation

Ive had great luch with the NOS 'Race Booster' octane. It is 20 per bottle but well worth the added HP and throttle response.

Do any major auto chains carry it?

I've seen NOS octane boost but not for that price.

Theoretically, how would a car run with a 93 oct program but only 91 oct fuel?
