Fuel Saving Tips
Coasting in neutral causes your fuel injectors to keep firing a small amount of gas in order to keep the engine turning over. Coasting in gear uses your forward momentum to accomplish the same thing - the ECU senses this and turns the fuel injectors off until your rpms get too low (typically below 1.5 - 2k). The disadvantage is a little bit more wear and tear on the clutch than normal. This is not a big deal as long as you're not abusing this technique by trying to coast down a steep slope in 2nd or 3rd.
