i just put a partial grill block on my 2006 chevy malibu, it helped me get better mpg's dont know exactly how much cause i changed my tire pressure to 43lbs and ! i drove to work about 170 miles away and around town about 25% of the tank and then back home! i got 43.79mpg's! my next tank that is all interstate i think i can get closer to 50mpg's while driving 55mph!
