REVIEWS

Chris,BMW X1 xDrive20d

I can comfortably do 50mph in 6th now where it struggled before, and revs are much quicker to get moving. It's still a big lump as you say;) but feels a lot more sprightly

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.
