What is your MPG?

Mine seems to be picking up a bit lately. With 95% city driving with most trips being under 5 miles, I am getting about 23 MPG now. On my rare hwy trips, I am getting about 29-31 averaging about 75MPH.

I was wondering about this too and why my MPG were so low...
I get around 15-18 on the HWY and prob something similar on the street
I constantly cruise control the HWYs at 75mph so I understand why that's low,
but when im not driving 75 and just going 55-65mph it still the same, why is that?

Pretty good! I was just thinking that my 31 MPG was on the way to the coast dropping about 1000 feet and with the prevailing wind at my back. I wonder how much that may have helped? Guess I should have payed more attention on the way back up the hill against the wind to check the difference.

C300 Sport/Palladium Silver on Black/P2
I keep a log of *every* fill up since I bought the car.
107 Fill ups. 29,000 miles. over $4000. Something like 1400 gallons.
Average comes out to 20.7 MPG over the 107 fill ups I believe doing calculation method. Computer AVG over the 107 fill ups is 21.4 I think.

I did 33,6 mpg during my trip from Cape Cod to Montreal this summer. 2 persons, 86F outside, AC on and the trunk full of luggages.
Not bad for a C300
My car is RWD and has a manual tranny

I routinely drive between San Jose and Los Angeles and average around 30 MPG in S mode. On my most recent trip, I experimented with C mode and didn't notice any appreciable difference.
In normal city driving, I frequently average just over 20 MPG.
One thing I noted, however, was that after performing my own oil change and filling with 0w40 rather than 5w40, my mileage seems to have gone up very slightly.

I seem to average 22-23 mpg city and 28-29 mpg highway.
( which I think is excellent for a 268 hp 3.5 liter V6 ! )
Much better than the 17 mpg / 25 mpg / 20 mpg listed on Edmunds...

Highway mileage
2009 C300 w/ 15k kms on it, just got 36.3 & 38 mpg on a recent trip, identical route 240 miles twice. Am happy with it.
Mind you I am quoting imperial gallonage, sorry guys , this metric crap throws me too. Always converting cuz can't get my head around 8.3 litres per 100 kms, means nothing.
tip; for all you Canadian owners who like the 'old' way, here's a conversion that is pretty accurate.
Take the kms driven & divide it by litres on the fillup. Than multiply by 281, but DON'T hit the = sign, instead hit %. You will get the old 'mpg' fuel mileage. It's not 100% but very close.

post script;
Just got my 09 C300 ( 15000k's) back from it's 1st service, was getting low speed brake squeal, and occasional smoke upon startup. TSB out on both. Fr pads replaced with upgraded pads, and reset encoding values on module for ' fuel sent ' on startup.
