How about MPGs? Wondering what you are getting with almost 10k miles on the engine?

f401

acquired on 11/19/2015. 850 miles on it so far. Getting avg of 26 Mpg

BlackC400

only 22.4 MPG avg, but i tend to have a lead foot

jonandgwen

Up to 11,400 miles. Average 24mpg C400.

Just returned from a trip to Italy. An E Class Taxi dropped us at our apartment. 2 years and 4 months old. It had 397,500 km (248,400 miles). The driver said he was half done before he would normally replace it. Just normal maintenance he claims.

Bought my C400 on Dec. 7th and as of today has just over 2,800 miles on it. Averaging about 20.2MPG, however my daily commute is stop and go city traffic and I tend to have a bit of a lead foot.

i have 6041 and bought the car on 11/30/2014.

how often do you guys change your oil?

e92miami

7768 miles and got it Halloween 2014 its asking for new oil in another 2012 miles. My BMW ran much cleaner getting up to 13-15k per oil change. That said this is a 4cyl turbo.

Wow!! I am awaiting delivery of my c300 hybrid but I am really concerned regarding the low mpg results that everyone is getting. My previous car was an f30 bmw 320d. With a very heavy lead foot I would easily get 40-45 mpg.

C300 4matic with 12,300 miles. Purchased on 10/12/2014. It's my daily driver and spend 80-90% on the freeway so the mpg would be a little better than those who spend a great deal of their time in the city or in traffic. Gets around 30-33 mpg on average per tank.

C_Class_Dad

C300 4Matic. After 1900 miles in daily commute (20 miles each way 13 miles generally at 60-65 mph; 7 miles at stop and go). I drive econ almost exclusively. Use premium (91+ octane). My long term average is 28.6 MPG. However, lately, with less traffic I am getting between 30 and 32 mpg (each way).

jonandgwen

16,820 miles. 24mpg. No issues or problems.

Everyone seems to be getting better mpg than I am.. 1/23 pick up, C400, 2860 miles, 18.8 mpg

Granted, I always turn off auto start/stop, do about 50/50 city/highway, and am usually in sport mode (but don't really drive aggressively).

C_Class_Dad

Are you using premium? I had my car in for work and the dealer gave me a loaner. Doing the same commute, I had worse mpg. He initially gave me half a tank. When I refilled with premium, my mpg went up materially (10 percent give it take)

eric123

Good to hear no problems..

topsider

7,200

BoboPolo12

Yup, Shell 93 only.

To compare, my 335i is rated at 17/26, 20 combined. I've been getting 20.6 over the past yr. The ML is rated at 17/22, 19 combined and that's just about what it's getting as well. Note that I'm just going by what the trip computer tells me vs. manually recalculating. The C400 is rated at 21/29, 24 combined and is getting 18.8 over the lifetime.

All are driven on similar roads with similar city/highway ratios. The BMW actually gets driven the most spiritedly, relatively speaking. I guess I could see what happens if I keep auto start/stop on and only use Comfort mode for the next fill up.. but boy, that sounds painful as I have a fear (perhaps unwarranted?) of the long term impacts on the engine due to restarting itself over and over..

C_Class_Dad

I run Econ mode mostly. I disable start stop when I am in bumper to bumper NJ traffic, or city where I hit the red light each block vi understand it's a beefed up starter. Like you, not so certain its that beefed up

bensales

I really don't understand that. You're turning off a system that is specifically designed to save you money and cut fuel usage in that exact scenario? Just throwing money away.

My car is now 7100 miles, run in comfort with start stop on all the time, and I've got an average of 47mpg (British) from new. I do a 50/50mix of motorway and urban, with bike racks permanently on the roof. As you can see, it's steadily improved over time.

And the interesting thing about this graph is, you can see exactly when the DPF regions have happened.
