Believe it or not, it's actually more fuel efficient to coast to a stop with the car in gear and your RPM's above 1200-1400, but with your foot off the gas completely.. plus it saves wear on your brakes since this will slow you down quicker than just coasting.. meaning there's less inertia for your brakes to have to absorb when you finally reach the stoplight. Whenever you coast with the car in gear and above 1200 or so RPM's and the clutch out, fuel delivery is cut completely off by the ECU and the engine plus all the auxilliary components that the motor drives are turned just by the motion of the drivetrain. It's not a huge difference in economy between just coasting and coasting in gear(because idling is not that fuel-intensive), but there is a difference.

 

If i am driving normal then is about 415m for me, Navi showed 24m per gallon. But if i drive a little faster then is about 380 with about 30m left shown on Navi.

 

about 500 wen i drove to FL but that was nothing but highway, around the city i think like at best 380 cause of my heavy foot.

 

I get 320 w/ 17 gallaons. I don't think i ever filled up gas at 18 or 19 always 3 gal left on my tank

 

My last tank (I just filled today) I went WOT at least 30 times and I still got 16mpg, and it was the best I've ever seen..even more then when I baby it which is very weird.

 

407 miles on this tank, filled up with 17.3 gallons of Shell's finest. so about 24mpg, AC always on, 70% highway.
