If your fuel consumption doubles then you have a serious fault(s) I suggest you have it looked sooner then later because if the fuel is diluting the engine oil you are in for a very big bang.

hey just got the message thanks for the reply how i was working it out is on the fuel guage £20 moves the guage 2 of the little markers on the guage so i was working out how many miles i got between them and it really has got worse also the car is using about 1 litre of oil every 600miles which to me is alot but it does say in the hand book that it can use upto that but am not sure if this has something to do with it also i have diognostics and have pluged it in and there are no faults so am not to sure its confusing me alot.

hey just had a look at that and yeah there is only a slight draw theres no gases puffing out or nothing like that there is quite abit of oil in the little pipe that goes from the air intake to that valve thing i have also had a quick check of the breathers and they all seem fine so i honestly dont know also another thing i noticed sometimes not all the time is that the brake are as if there is no servo then all of a sudden work as normall not to sure on that eather dont know if that could be rleated to vacume somewhere along the line. also i dont know what made me try this but the other day i put my foot to the floor and the car pulled then i put my left foot on the brake basically "left foot braking" whilst i kept my accelerator to the floor then i let of the brake and the car basically had no power for about 5-6 seconds then picked back up again dont know if thats normall eather as i have never known a car to do that eather.
