Average mpg

I'm just wondering what other members are getting from their slk in terms of fuel consumption. On my first 250 miles i've got an average of just over 23mpg. Will consumption be better as the engine wears in?

See post 76:
It is now 7.2 L/100km or

39.2 MPG CDN!!

Lens latest figures!

I have been driving my SLK for 10 months now and I am extremely satisfied with its fuel consumption. Actually, the SLK has been the least petrol-hungry car I have ever owned. Since your car is still in the running-in period, it is normal that it consumes a little more. Here are some causes of higher fuel consumption:

Running-in period
Excessive city driving (or extremely slow driving)
Bad tyre condition (or use of winter tyres)
Extreme speeding
Using the A/C
Very cold temperatures

Some SLK owners say that driving the car in the S mode (as opposed to the C mode) is more fuel-consuming. I tried both. The difference is insignificant, if any. Hood-down driving is not significantly more fuel-consuming either. Of course, if you drive wrecklessly in any mode, you will pay the price!

Here are my personal consumption figures (you must take into account that I am a rather conservative driver):

In warm temperatures, I get an average 7,8 litres/100 km (city/motorway). That is about 36 miles per Imperial gallon or 30 miles per American gallon. On a good motorway, if I drive reasonably (100-120km/h or 60-75mph) I can get 7,4 litres/100 km (about 38 miles per Imperial gallon or 31.5 miles per American gallon) which is an excellent fuel consumption considering the weight of the car and the type of engine (mine is a 350). In colder temperatures, with winter tyres, my city/motorway average is 8,5 litres/100 km (about 33 miles per Imperial gallon or 27.5 miles per American gallon). City driving alone is much much more fuel-consuming. I get an average 11,5 litres/100 km (about 24.5 miles per Imperial gallon or 20.5 miles per American gallon). And of course, driving in extremely slow traffic with the A/C on can increase the fuel consumption considerably.

I hope this will reassure you a little! Have fun with your new car!

To be honest, i thought 23mpg was good, and was only hopeful that it would get better.

Thanks for the detailed info Zut.

I haven't driven the car properly in S mode yet, just kept it in C and gave M a try. I did switch to S, but it was on my first day behind the wheel, and after about 30 seconds i switched it off! Now i've bonded with the car properly i think i'll give it another go when the streets are clear.

I averaged 25.7 MPG over the last 6000 miles of city and highway driving. I have seen it go as high as 28 MPG on the highway between 75 and 80 MPH.

It is not recommended to use the S mode during the running-in period. I don't know whether the risks are real or not but I chose to play it safe. You mentioned you had the M mode. Here, only the SLK55 has this option. The 350 has the Touch Shift stick but not the C/S/M button (just a C/S). To be perfectly honest, I never really understand this pseudo-manual setting and I only used it a few times (not enough to appreciate it's related fuel-consumption).

Anybody know what the optimum speed/rpm is for fuel efficiency?

I'm quite impressed with mine as well, I'm avging 23-26mpg city and close to 30mpg highway. My other SUV's both yields a little over 19mpg. Can't complain, it's my gas saving car.

Thanks for the advise Zut, didn't know not to use the S mode during the runnin-in period, so i'll hold off on that.

When taking slip roads that lead onto motorways they tend to bend round pretty hard and last quite long, i've been hesitant to really push the car around these bends (just to see what it can do), as i'm still don't know the transmission that well and i'm afraid it'll drop a gear and give me a boost when i don't want it. With the manual, it'll hold the gear and i'll know what to expect.

I get about 14mpg for everyday driving and about 23mpg on motorways.

Driving in BKK with a SLK200 is like driving in America with a fully loaded SUV, petrol wise. Traffic and long red lights.

Not everyone agrees as to what should or shouldn't be done during the running-in period. Maybe a member of this forum can give you some advice. It is always a good idea to drive rather conservatively for the first 1600km/1000miles. Don't you worry, you will have plenty of time for more exciting driving once the car is fully run in. I am sure my excellent fuel-consumption is partly due to extremely careful driving during the first months.

Chris, I have just over 600 miles on my SLK 350. My car was in "S" mode when delivered, and I have left it there. My mileage, in mixed driving, has been around 20.3 miles per gallon. I haven't taken any trips, or done extensive motorway driving. I imagine that it may improve a bit as the engine breaks in, though I don't expect a huge increase in mileage. I think that the automatic transmission, coupled with the occasional need for a burst of speed, will ensure that mileage stays down. Dinomon

I have kept track of my fuel consumption using a software program and after 4100 miles, mostly around town, I am averaging 15.7 mpg.
