Just went through my first two tanks in my MY04 CRD.
Cleaned a (very) clogged MAP and driving around Newcastle to work 60-80 kph yeilded about 10.5.
Disiabled my EGR (screwed the bugger closed as per the thread) Then towed my 7x5 box trailer + KTM to Taree for a ride and got 9.9 !!!
Very happy. Uses less than my 05 XT forester does towing nothing!! Only sad part is it sits 50mm lower
