I think it calculates based on the MPG of your last trip. I have observed this too.

I did something today and it brought the L/100km down. While I was driving I reset the start trip mileage clock. I drove on Eco and on average got 8-9L/100km.
I then drove on Comfort and did exactly the same thing on average I got 9-10 L/100km.
I noticed I always start 20L/100km if I reset everything.
is something wrong with my electronic fuel gauge or you guys get the same?

dhaval

I never tried resetting. But can try this next time I go on a trip.

How much efficiency do you get for city driving and high way? Are you on comfort setting?

dhaval

I don’t drive much on highways. But I get 9.1 in the city. I drive on comfort all the time.

Not exactly an apples to apples comparison, but here is the trip meter after a longish highway trip in my wife's C400 (we call her Fraulein). This is through some pretty steep mountain passes in comfort mode 100% of the time, consumption on flatter terrain would have been better (2015 C400 with 93,000 Miles).

That’s great for C400 7 L/100km.
I’ll be going on a trip tomorrow and will definitely check again by resetting the start trip.
My car’s ODO is 58,000 KM. I called my dealership they said it’s normal cause it’s C250 with higher power engine. You guys have more powerful engine C300 C400 and getting a better mileage. Not sure what’s wrong with my car.

Mine is 2 ltr turbo.

Hi all I did 530km 50km average speed and got 8.1 L/100km (aircon on plus in Comfort mode)huge improvement from 13 L/100KM city driving.
Is city driving this bad of a mileage for my car?

dhaval

City mileage is always bad. It’s because we break a lot and stop a lot.

justanick

Does that mean our start stop function is consuming more fuel and puts pressure on our car? We you turn it off?

dhaval

No, I was talking about breaking the car more in city traffic than on highway has a huge impact on efficiency.
