We’ve had a number of diesel Renault Scenics/Grand Scenics and the final one we had averaged 51.8 MPG. We do very little ‘town’ driving on a day to day basis, a lot of our driving is on twisty single track driving and up and down hills. We changed to an Ateca petrol and now find our average is around 35 MPG as against the 51.5 we were led to expect. Given the price of fuel in very rural areas this is making the car unaffordable for us. We never had a problem with the DPF in any of our previous cars.
