Fuel Saving Tips
In conjunction with the tip "Slack your speed" I find it useful to put my car in neutral whenever going downhill. even on the slightest downgrades you will actually find yourself going faster than if you had left your car in gear. I drive 25 miles to work and find that I have 1 4 mile section where I'm in neutral at 800rpm and 4 more section I can coast a mile with no foot on the gas. All the while you engine is saving 1000 to 3000 rpm for every minute you can keep it in neutral.
