The C-Class GAS MILEAGE thread
Scott
Thanks...next time I fill up I'll take note of what the computer says my mileage was and what the actual was an post - I believe there is a huge difference between what the computer shows and what actual is.
Very sweet.....Wait, where do you live? any hills?
Cause I got an average of 80 MPG going 8 miles down a mountain road. (Gatlinburg)

There is really little wind resistant plus the tail wind was helping, so I guess thats why I got the 39MPG. Plus I just got a oil change w/ Mobil 1 and put +2 Psi on all the tires that same afternoon, don't know if those things help any with the gas mileage at all.
Anyway, The new benchmark is 39MPG!!!
I'm not going to get 25mphs for every 1000rpms in 1st or 2nd gear...
I can tell you my RPMS are at in 6th gear at 80mph though, once I drive home...
I think when I had an automatic loaner the 6spd auto was shifting pretty darned close to where I shift my manual.
I'll double check my 6th gear on my way home.

I love tucking in behind 18 wheelers. They suck me right along and I get outstanding gas mileage....I made it 15 miles, with my computer saying, "0 miles to empty" by drafting a big truck. I was shocked I didn't run out of gas...I think my fill-up took 16.3 gallons, so I was riding on fumes.
If I would have had a co-pilot, it would have been just like the Seinfeld episode where Kramer took that car on a test drive.

I have almost had my car for... 9 months now.., and I expected the gas consumption to be less after the break in. It's around 9600 miles (or 14500 km), and the average is at (20.6 mpg) or 11.6 L per 100 km. This mileage sucks, especially when it's advertised to be much lower. I know some people would say it depends on how you drive, I DO NOT slam my foot on the gas, and even on highways AT MAX I get around 23.5 mpg or 9.5/11.00 L per 100 km.
I am taking the car for service next week, and i was wondering if I should address this to the dealer. I was at the e90post just now, and the 335i Coupe gets around 23.5 mpg.
What's with this?
Model that I have is : C280 2007
Thanks guys
I'm a e90post member, too. I come to this forum to get more info about my wife's new 2007 Mercedes C230 that we picked it up last Saturday. I think the C230's average highway mpg is around 23??

First of all don't go by what the computer on the dash says, not that accurate, do it manually when you fill up
11.6L / 100km = 24.3mpg (imperial gallon)
9.5L / 100km = 29.7 mpg (imperial gallon)
US mileage will be less in mpg as their gallon is 20% smaller
I think that is quite respectible for a 3L V6 car. Don't forget that the Transport of Canada ratings are fantasy, i.e. driven in a lab, with no starts and stops, no wind resitance (car is stationary) and no rolling resistance as only the wheels that are powered are on a roller.
Give you a reference for my 1.8L Kompressor
Best 6.7L/100km 42.2mpg (highway at 108km/hr on cruise)
Worst 17.1/100km 16.49mpg (city driving in February when it was -15*c)
Average 12L/100km 23.5mpg (mixed driving, and gunning it when I have to)
average highway 8L/100km 35mpg (driving at 120-135km/hr)

So, i guess 20 MPG isnt a bad rating at all.
