Miles per tank.
Yeah ok, so I have a C230. I just filled up my tank after 505 miles with the computer saying I have 30 to go. I really love this thing. It may not be super fast but it sure is comfortable for an economy car.

I have once seen readouts where the computer estimated my range was over 700 miles a tank of gas if I were to continue driving at a steady speed of around 55 to 60 mph. This was on a 2005 C230 Kompressor Sports Sedan automatic with 32/36 PSI tire inflation (Front/Rear) in the United States at low altitude.
Now, I have to start wondering, if I were on a long road trip (say 5000 miles) and I were to continuously go 55-60 and achieve 700 miles per tank vs going 65-75 and achieving only 450 miles per tank, and assuming that it takes about 10 minutes to fill up (get off the highway, stop the car, fill up the car, and get back onto the highway); it seems like it's barely worth it to speed, since you barely save much time at all. Naturally, driving 55-60 on a highway may not be a safe speed, and 65-75 might be more close to the flow of traffic. Therefore, one should not attempt to "hypermile" even in the name of science.

My C230 has never achieved that, although I know it is capable of it. I just never have taken it on a long road trip. I get 375 miles to a tank - consistently. It's a mix of driving.

The gas mileage is definitely a downfall of the m272 2.5L. City driving is right around 20 for me, and even driving highway (mixed with some hard driving) my average for owning the car is only around 24. This really isn't THAT bad, but my old CLK320 averaged 25-27 the entire time I owned it. If I drove it hard, like I do my C now, I would still average 24 a tank.

I was just about to add that I love the 7sp because of the amazing highway mileage. In 7th the faster you go, the better mileage you get!

I'm not really all that concerned about mileage. Did you like how the car performed with the sprint booster, other than the mileage? Do you still have it, or want to get rid of it?

No, I sold it like a couple years ago. Well, it's basically just reducing the amount of effort when you push the gas pedal. You'll like it after you install it, but you need to adjust how you push the pedal. I was like reving after I installed it, cuz I just pressed it like it was without the booster. Definitely fun, but watch out for the popo...

These pictures as I progressed on my trip. 
I only drove about 20 miles, and there were no hills. So this isn't something I could sustain for long drives but it's the highest I've seen this read. The highest I've seen it read over a long distance of like 90 miles was a consistent 34mpg.

This is because a 05 C230 Kompressor with the 4-cylinder supercharged engine seems to be designed to have gear shifts done at closer 3000 RPMs during normal non-aggressive stop-light acceleration, while the 06/07 C230s with 6 cylinder engines seem to have gear shifts done at lower rpms during normal stop-light (at least with my driving style).
Having driven C55s on a few very memorable occasions, I can say, the abundance of power in reserve is a great comfort; driving C230 Kompressors, one has to be careful to be in the right gear during tricky merges onto freeways to ensure that adequate power is always available should one call for it. The C55 and even the C320/C350 cure this problem as power is usually sufficient in any gear.
