better mileage for my 2006 malibu

[joesgot4]

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!

Yikes! Yeah,changing a couple variables simultaneously makes it really tough to nail down what each modification contributes.You might consider restoring tire pressure to your original specs,redo your test loop,and if all other factors haven't drifted too much,the grille block data should fall out of your log book.The difference will also identify what the pressure did for you.

43.79 mpg in a 06 Malibu and your complaining.
