Here's something new to figure out. A couple of weeks ago I cracked the lower front bumper. Both of my driving/fog were broken. I took the lights out and put the black covers back in, because of the cracked bumper the right side cover fell out. I am on my second tank of gas and now my mpg has increased to 28 mpg average. Also seems to have a little more pep. I am not complaining just wandering why. What do you think?

 

GM is looking for new engineers like you

 

dont know how to explain this...but I'm off to crack my bumper right now for some extra mpg!

 

 

ummm

 

Where is my sledgehammer?

 

You hit your head when you cracked the bumper?

 

I had a piece of metal in the road blow up into my bumper cutting it across the front and have not experienced any change in mileage. Mabye I hit it too hard?

Knock the other fog light cover out and see if you get over 30 mpg...

 

Well when my bumper was crack and bent up, I could not even drive mine so you really are lucky to get getting better MPG what about horse power?
