mileage
From these posts, it sounds like a new LML's fuel mileage isn't too far off of what I was getting when my LB7 was "new"- about 15-17 combined C/H driving. After a good break-in period, my mileage began climbing. It's now got 270K on it and frankly, mileage has become a reflection of just how heavy my right foot is! The LML, as I see advertised, is supposed to get better fuel mileage than its predecessors, but my LB7 will get (empty) ~21 mpg (highway) at 65-70 mph. Back that speed down to ~57 mph and I get better than 25- no B.S.!!!
Once these new LMLs are "broken in", I wouldn't be surprised to learn of highway mileage in the 20s. The biggest challange for any driver is having the "patience" to drive at reduced speeds.....
