Ride your bike to work. Seriously.
That would be funny with 30 km from home to work, and three children :bigggrin:
Seriously, there are several standard procedures for keeping optimal mpg.
-Use your car only when you really need to.
-Drive at a speed as constant as possible.
- On downhills, use engine as a brake. In that situation, fuel consumption is zero.
-Avoid stop-and-go by anticipating and keeping your distance.
-Remove unnecessary roof racks, CB antenna, etc.
-Keep tire pressure high (within allowed limits)
-Shift gears asap. Keep ECT PWR button off.
-Keep oil clean and at proper level.
-Dont leave engine running on idle for more than 2 minutes.
-Remove unnecessary weight from car (e.g. recovery gear, while not on the trail)
Etc.
You can summarize most of this in: use your common sense.
