I am currently getting between 18 to 20 mpg on my daily highway commute.. unless there is a reason for me to mash the gas pedal.. which I do somewhat often 
Especially when I am in a tunnel.. open windows.. jam pedal... listen to the music...

I'm not too familiar, but I checked display on the dashboard and it says 25L/100 for 380KM travelled (I have 400km now, picked it up at 20km on the odometer), I will be paying attention to see if there really is indeed a problem and bring it in to the dealer..
appreciate the help!

My favorite part of the car is when you turn it on, the "Since Start" shows 16mpg...then it slowly goes down as your start driving in town...I love showing people "Look, my car gets better gas mileage while idealing in the driveway at startup".
Anyway, 360km for 2 fillups means a refil at 180km...which is about 110miles...I'd argue that even if he is filling up when the "Reserve" light comes on, he is still not getting the mileage he should. That means on 11-12gallons, he is getting less than 10mpg...Unless he is crawling around town at 15 mph, or is constantly rubbing the pedal, he should be getting about 13-14mpg, which means, 140miles or 230km per fillup.
I'd monitor for another tank...if you can't get above about 550km on this next tank, I'd have her checked. Even low tire pressure and running A/C wouldn't lower you that much.
Was this car previously owned? If so, hope it is CPOd.

Yeah see thats the thing, the OP might be getting low KM's but he might getting heaps of hours because he is always sitting in traffic.

Hey everyone,
Just picked up my baby last thursday..but 1 quick question!!
On my odometer it says I have travelled 360KM since..but I starting my 3rd tank of gas!!! I know the gas tank is relatively smaller (I came from a CLS500), but I have been getting gas basically every other day! And yes total KM travelled from this morning is 360KM!
I know this car is a gas machine, but just want to make sure if it is THIS hungry!
Please chime in!
Thanks

I find I get my best mileage when going constantly at around 120-140 km/h. I check the dash each time and my mileage hovers at 13-14l/100km at that speed. When driving from 50-100 constantly and for a long time, my mileage actually gets worse.
I get about 300-350km on a full tank.

I also noticed MPG is more favorable when holding a consistent 60+ on hwy. This car doesn't like to go slow. 
With a full tank, I'm happy if I get 300 miles out of a full tank after combined street/hwy driving. On a recent trip from LA to Vegas (night driving), I got a good 20+ mpg the entire way there.
Some of the forum members mentioned changing air filters to K&N and removing charcoal filters adding an additional 1 mpg. I'm going to do that this weekend and report back in a week.

Just over 10K miles and I am averaging 16.5 MPG mixed driving. The onboard computer ALWAYS calculates MPG at .7 to 1 MPG higher than hand calculations!! What's up with that??
Gas mileage is not this cars strong suite, unless you own major stock in an oil company

That's $104.27 US, insane for a tank full. But with the current administration who wants the US to be more like Europe we'll be paying the same very soon!!

I get really good figures on the freeway. Car is at 5000km, with a hard break in.
I just did a road trip this weekend (2000km) and on the way to my destination I averaged 11.4L/100 (sitting on 120km/h), then on the way back which was more winding country roads and also involved climbing up to higher elevations (up to 1km above sea level), I got 12.8l/100, and that was averaging 150km/h with occasional bursts to 200+ AND some winding road which involved manual mode and ESP off.

The cost of refinement varies based on which country your in, labour costs, etc etc, not to mention that EU taxes on fuel are significantly higher then the US.
My bet, is that when you remove taxes, and get down to the base cost for similar process to create the fuel, the costs will be somewhat similar.
