Thanks for the replies, I'm taking the car back for repairs due to the handbrake being stuck on a little bit and the tracking is off the the right, I've just put 20 pounds in which was 15 litres and it's done 160 miles and still going ... The car has got a tow bar and I think the fear box is wrecked as it won't go into 4 th or reverse gear properly, the car has 65,000 on the clock with full service history, the engine is emaculate condition not a speck of rust, there's no smoke at all not even when it's starting up, it pulls like a train without going above 2000 rpm at all times. I've been looking on line for research and it says if I got an induction kit I would get even more mpg. Why if I'm getting 45 mpg on average does it say I'm getting no less than 60 mpg on average, but why the big gap? Just to add there's an orange symbol on the speedo clock behind the steering wheel, it looks like an engine management light but I don't know what it means?
