I can get 25mpg in my 00 if I drive 65 on the freeway (which I really cant do often) usually its 23 at 70 or so. Just be happy the gas is what it is by you, because I can GUARANTEE you its a lot more here. My favorite cheapo gas station just jacked the price of unleaded regular to $2.99 this morning!!!

Slowing down will definetly increase mileage but, honestly, there aren't any of the aftermarket products that will do anything for your fuel economy. Gary

You have just derated the HP/torque output, fuel consumption of the engine to whatever level, 10-20-30-50%, you chose to block the throttle opening.
