Hey, I know this is not Smart Related but my other car is a petrol 1.4 mercedes A class, it is a 2003 model.
I have been concerned that the MPG is a little cr*p.
Today I filled the tank up to the brim and took it on a 50 mile journey not exceeding 60 MPH and keeping the revs around 2000 rpm.
However the MPG was still in the high 20's, over the past few months we have been struggling to get 30mpg and I just assumed it was due to my wife's short journeys but after today I think there must be something wrong with it.
In the past 6 months I have replaced the air filter (with a merc one), replaced the spark plugs with new bosch ones, changed the oil and filter using a mobile 1 0/40 oil.
Could it be a leak or something else?
Thanks in advance.
