Still very pleased with our GLK250 after 29,827 kms and 47 fill ups. with regular driving we've averaged 8.1 l/100 km , 29.1 mpg us or 34.9 mpg UK. I don't think that is too bad considering the majority of my wife's driving is in town.... Sure we've done better (and worse) at times but this is a long term average without even trying.....

Anyone else as pleased over the long term....

 

We have only done about 18,000 km on our 2014. I stopped keeping track of fuel consumption because it was nowhere near what some here claim. Ours is about like yours. Last time I reset was about 6000 km ago and I think fuel consumption is about same as yours.

No problems with GLK at all. Find it a bit small compared with other makes, but nothing I can do about that!

 

Lovin my 2013, great mileage and fun to drive, the diesels a blast..

 

My 1989 Land Cruiser just got a decent tank at 10.5MPG, although I do use it solely for around town and beach duty. So that mileage of yours is pretty good compared to some others
