How do you drive? If you are always in high traffic, stop and go, you won't get much better milage than you are having now.

That won't erase the adaptive memory. The only way I have found to do it properly is disconnecting BOTH battery terminals and connecting them together for a minute. I use a piece of metal, an open ended wrench because mine don't stretch that far. Reconnect them. Turn the ignition on without starting it, Turn headlights on and then turn them off. Turn ignition off and wait for the click. Then all good to go. I usually cover my battery with a towel to keep from accidentally touching them while grounding my terminals together.
