Fuel Saving Tips
With more modern cars switching to Direct Injection, you'll want to start coasting while in gear instead of in Neutral. In these engines fuel is generally nearly cut off if the car is in gear and moving, utilizing less fuel than if your car was in neutral and having to fuel itself to maintain idle rpm. If you have a way to monitor your AFR you'll see it go into the 40's and 50's instead of 14's. This is not only safer while coasting down hills or to stops, but now it's rewarding as well.
