I have recently purchased a 2005 1.4Tdci and I am finding the mpg I am getting is very poor compared to the ford guide.

I previously drove a 1.4 Petrol Zetec and was gettiong about 48 mpg on my journey to work which is mostly motorway and some a roads.

The new car is getting about 55mpg at best. I am not driving this car any differently, I do not accelerate hard and keep to 70 mph.

I wondered if anyone else had similar problems or knows why this is. Is there a reason why this is? Could there be a problem with my car?

Also while doing 70mpg on motorway there is some vibration/movement in steering wheel. Is this normal?

Thanks

Mike
