Hi everybody, Has anyone had any experience with the LE5 Ecotec engine? After almost 5000 miles I still get lousy mileage and I drive very conservatively (give the price at the pumps) and I use a Scangauge to monitor it as well. The 2.4l VVT engine isn't supposed to burn 11-12l/100Km; for city driving they claim 9.6. I figured until the engine loosens up a bit, that's normal, but it's still about 20% higher. Thanks.
