It means you drive around in D all the time or short shift the 6MT, these cars need regular high RPM runs and sustained RPMs to burn off the crap on the valves.

I'm at 55k miles and my valves do not need cleaning, I've run meth for ~10k miles but I drive in DS even on the freeway and my car gets a workout to and from work
