Is your Mach Z Stock?  If so 92 or 93 Octane,   You could run 110 if your sled is stock,  but you will lose a ton of performance.

I remember the octane discussion from earlier this year.  I believe the result was: run whatever gas the manufacturer recommends, if your sled is stock.

You know a guy has no clue when they want to run the octane.  For those that don't know, You want oto run the lowest possible octane you can without detonation. I have afriend that has a 540" stroker that makes 650HP  & 725 Dyno proven Ft. of torque while running on 87 octane. Has been for two years and 20,000 miles. Knowlede is the key to motors survival. And we'll all be more knowledable with ZMachman back.
