03 1.8 Diesel fuel economy bad? - Felics
Ive noticed recently that the amount of fuel that the car uses has increased significantly. I used to get aroun 40MPG and now i barely make 20. Its happened quite suddenly and i was wondering what could possibly be wrong with it?

Ive changed the oil, oil filter and air filter within last 5 months. Howver i have bought a new battery (bosch s4005).

any ideas?
