I have a 1996 Audi A4 1.9 TDI SE which is currently averaging 43 miles per
gallon. I have a 40 mile per day round trip to work down winding country
lanes and few a couple of small towns so I know that I won't get the same
economy as I would with a straight run to / from work. However, I would
like to know what changes I can make to the car to increase fuel
efficiency - Any Ideas?
