I have just done my first fill up on a N reg 1.6 Honda Civic and it shows a
return of 27.5 MPG. This seemed a little low to me. I am sure when I used
to drive cars of a similar age I always managed a minimum of 30 MPG and a
little more on a motorway run.


Seems low. What's the state of the exhaust? I used to reckon on at least
15% improvement whenever the exhaust was replaced on my petrol Polo. Can't
say I can give a good reason for it, but it made a difference.
