Hi All

a long story which I won't bother with, but in short, filled with petrol, recovered to an Indie I did not know, who carried out various tasks, then fitted new injectors! I have repeatedly complained about poor economy, with the promise that it would improve!! 10k miles now and no improvement, used to get high 40s on a run, even a 50, now no matter how I drive it seems to average around 36-38mpg.
Any ideas or suggestions as the cost of the black stuff seems to be rising again.
