Don't do EOC in an automatic-equipped car. Coasting in neutral should be fine; I've been doing it for a long time in the Forester at speeds up to 75mph (we get some steep hills here in the Appalachians) and suffered no ill effects, but the front end of the tranny has to be turning to keep the rest of the tranny lubed. You can coast with the engine on, and turn the engine off at lights, but when rolling, the engine should be on.

And yeah, it's worth it. A Forester is heavy and shaped a bit like a LEGO block, but I've dragged its mpg up from an average of 25 to about 29.1.
