Fuel Saving Tips
Use inertia to your advantage. Even if it's not possible to build-up momentum before entering an incline (traffic can play havoc with the best-laid plans), still lift off the pedal as soon as possible near the peak. From this point, it works the same way--built-up energy carries you over the crest while the hardly-working engine practically idles along.
