Over the last little while my 2003 E320 has started to give me really poor fuel economy. Sometimes I get a smell of diesel in the car. I've had s good look under the bonet and have not been able to find any fuel leaks. Also there is never and marks on the floor after I park.
£25 will give me aound 110 miles when not booting it around!
Just wondering of anyone else hs experiened this. or what I should look out for.
