Mark ,Ford Mondeo 2.0 TDCi

Not only the fuel saving but the car is smoother to drive and has more power through all the gear range.

Dave,Kia Sportage 2.0 CRDi

I turned my Advantage up to 6 same as the Sportage you put on test and I have my K&N air filter in. We went to Southport from Wrightington through Mawdesley, then Rufford and Holmeswood. We came back the same way and my MPG was showing 40, an increase of 8mpg.
