Only 23 mpg with my '02 M6???
this is in my 382 stroker with all the bolt-on's, M6 and 3.42 10-bolt. I'm pretty happy with it <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> , 457rwhp/448rwtq.
Around town I usually get around 18-19.
48000 miles now
Also, does the guy with the poor mpgs have speaker boxes to tool boxes int he back? weight and tire pressure affect mpg bigtime! For what its worth, my 383 IROC got better gas mileage than my 94 3.4 V6.
