I'm getting 30mpg from my MCS, this about right?

It's now got 400 miles on it, average speed is 35mph, some highway, some stop/go

 

That's about right. I get 30-31 mpg, avg speed is about 30mph in town. 5000 miles.

 

Thats execellent. I get 25 with mixed driving in my manual MCS

 

Yep, the EPA figures aren't real world tested but algorithim based so if you get them you are generally doing very well. 30mpg is about what I get on my 05 MC so if I can get that with the new 07 I'll be very happy.

 

I was getting an average of 33 mpg in my manual S and am getting about 26 or 27 in the AT.

 

it really depends on driving style and what type of driving (mods if any) how hot it is, AC vs window usage, blah, blah, blah...

I'm getting 31-33 typ. hwy in an R53 manual (which supposedly has worse mileage than the R56). I've seen 35 highway (for the tank) when I was stuck behind a tractor-trailer on 80 going through PA.

 

I just returned from my first 'real' trip with my MCS 6 Speed - 1900 miles. My average was 32.8 mpg and that included about 2/3 highway and 1/3 small town driving. I didn't look at my average MPH after the trip though.
Before the trip I was noticing ~29-30 mpg mixed driving.

 

seems your average speed is really important to the MPG result. I also think the sport suspension and the tires you have will affect it, too.

And, of course, if you drive it like you stole it, which I seem to do... I'm running consistently about a 25avg mph and getting about 24mpg.

I'll blame the 17" runflats for now... <grin>

I just filled up for the 1st time yesterday and my MCS with 400 miles on it got 28 mpg, with mostly city driving. My last car (Nissan Xterra) got 16 mpg if I was REALLY gentle with it, so 28 mpg is not too shabby if you ask me!

From what I hear, the gas mileage increases a little as the engine gets broken in. Works for me!

 

My average over the last 3 tanks has been 45mph with 38mpg, sport suspension, runflats, and sport button on all the time.

 

I've been tracking mileage on my 2004 MCS since new, now about 20K miles: 24.1 mpg overall. It gets about 21-23 around town and 29-31 on the open road at typical freeway speeds (65-75). I do more around-town, so my overall is nearer the first.

Everything I'm reading says the Gen II should do about 15% better, so if I bought a new one, I suspect I'd get about 25/34. Certainly not good enough to justify getting a new one, but definitely something to factor in.

It is what it is. Just don't rely on the trip computer. Divide your trip odmeter miles since the last fill-up by the number of gallons it just took to fill the tank. Adjust that number as necessary if you notice the trip oddmeter to be inaccurate.

 

My R53 got 27.5 mpg on my regular commuting fun. My R56 gets 32.5 mpg. I'm pleased.
