C63 - " it's not bad on gas it's actually really good"
I wish the gas tank was a little larger though so the total range was higher.

I agree, a bigger tank would be great.

Not that it should really matter in THESE particular cars, but the only way to get an accurate figure is by simple math: miles-driven ÷ gallons-pumped

I saw 20.5 MPG doing around 70 constant on the parkway for an hour, looked like it might have climbed a bit more if I was to have driven like this longer.
At this point I replaced the rear oxygen sensors, they may be related to the trims and they seem like they may be worth in my car .5 MPG. These are not expensive, got the pair for less than $100, OEM boxed.
I'm still getting just below 13 MPG in commute, but I saw the news with OPEC, the fuel price may be going up.
If it goes back into the $4's, it's worth having the car fuel system work 100% as designed. I will do the front sensors next.
But... the wagon weighs 600 lbs more and has one less gear.

Got that just after I got the car in September after a reset once I was on the highway for a 2.5 hr run. Never had the opportunity to see it again. I averaged 18.4 mpg and about 35.6 mph on mixed driving over the long haul of time. Doesn't change much. It is worse than my 2011 E350 wagon that averaged 22 mpg and the CLA45 AMG at 24.6 mpg but the fun quotient is well worth it.

But going to the point of the guy with the advert...I actually do think these motors aren't as bad as the 6.2l size would have you believe. I mean...it's a damnsight better than my E39 M5 on fuel, that is for sure. I never moan about how quickly the fuel goes down on my E63....but for some reason, I always do in the M5. That's a lot closer to 11-12 around down while the E is 15-16...only 4mpg, but another way to look at it is it's around 30% better.
On another note though, the possibility of me having clogged up cats and having the fuel leaned out accordingly is probably a factor also.




But for the sake of this thread, I included my possible cat issue because the car seems to be a little bit better on fuel than the others etc, so i thought it was a relevant point to make (esp as the AFR's are nice and lean via Jerry's tune)



. May I suggest getting some Exxon stock to get some ROI?
