Yeah, but check it after driving a full tank, that would be much more meaningful. Running down the highway at 60 for an hour or so doesn't get any of the stop and go, which is much more real world.

I've been tracking mine for the last two years and best I have ever gotten is around 27 straight highway for a long trip and around 24 for my normal commute which has a good amount of highway miles in it now. If you get 30 on a full tank with daily driving, you got something real special there.

I can get 31mpg in my 4matic wagon on long highway trips (300 to 400 miles) if I keep my speed between 65 to 70mph. (with a full load of passengers and luggage). This is using the # gallons pumped vs miles driven method, not via OBC. Very impressed with the highway mileage of this car. Around town though, I get 16 to 17mpg. but that's lots of stop and go and speeds usually in the low 20's and trips usually less than 3 miles.

I don't bother tracking my city or mixed used driving because I know it will be in the teens. My point was that on straight highway driving, this is fine MPG that is about 3 MPG better than a V6 Accord that weighs 500 lbs less and has less HP and has a cylinder deactivation system

I get 33 on my Mercedes Benz E350 V6 going to Florida and to Myrtle Beach. That is doing about 75 most of the time. Best car I have ever owned for highway driving.

Did you try to measure how much gas actually went into the tank? Mine is usually off by one or two MPG so it always take a little more gas than it should.

I get 25 hwy and 18 city on the wife's car. I also get about 12 hwy and 8 city on my daily driver. My daily driver is the worst car I ever had for gas mileage.

The best I ever got was 33 mpg on a 425 mile highway trip.

Since I've got the car I've put on 8993 miles and am averaging 26 mpg, both city & highway driving.

I am very happy with that!

All of my mileage lately has been combined city/hwy... 17. But I do have that tune, so I'm a bit more heavy-footed these days. Would like to take it on a road trip to see how it does though... maybe this summer

Getting about 14-15 mpg in combined city/highway driving but I do live in NYC. Tried it out in Economy mode and sport mode and barely a difference when driving mostly sane speeds. 48k miles on my 2014 E550 with pano roof and airmatics if that makes a difference.

I have an E550 (V-8) and I consistently get in the high 20's on the highway. I even remember seeing it go over 30mpg on the highway when traffic would only allow me to drive around 60mph.

I'd be careful with that lol... Mine stalled and would not start as soon as the needle was flush with the 0 line... haven't let it get that low since then (although I've come close)... fortunately I was next in line at the gas station, so all I had to do was push it 20 feet forward while my mom laughed at me lol. Although I will say it could've been because I was on an incline, so maybe that's why it stalled at exactly 0.

SEC1939's mpg of 51 is awesome! That may be my next car!

As it is, I'm driving an E550 (W211) and have averaged an overall 28+ mph for the last 60,000 miles. Commute runs over 30 are common with a best of 33+. And I always try to get a 0-60 blasts in.

A screenshot from a round trip from Calgary to Portland and back equivalent of 43MPG. Some city driving included. We can regularly get below 5.0L/100km (47MPG) of pure highway driving. Car is 2014 E250.

Sadly my leased 2014 E250 (W211) will be turned over to MB in the next few weeks. It is being replaced by a GLC300 (gas). The mpg is going to suffer.

The best I have done with my E250 was on a trip (750+miles) from South FL to Asheville NC. On most of the trip I was 47mpg or so but when I got into the mountains of NC I did 54.7mpg. Think it was do in part to coasting on the down legs. I do a lot of city and not very much highway (40+). So my average is 29mpg at an average of 21mph in very HOT FL.

What year is your E Class? I'm assuming that it must be a 2012+
