Question by Harajuku Chris: H2 (Hummer) Question! Car!?
Alright, so I just turned 16 two weeks ago, and my parents made me wait for my present for two weeks ( I was bummed, but they said it would be worth the wait ) and they suprised me with a brand new H2 Hummer icon smile H2 (Hummer) Question! Car!?

ANYWAY
Currently already, I am getting 11MPG, but I’ve heard rumors that the more I drive it, the better the gas milage will get. Is this true?

I can provide pictures if needed.

Your gas mileage might increase just a little bit as the engine and drivetrain goes through its break-in period (the first thousand miles or so), but not substantially. At the most you might see a 0.5 MPG improvement.

After that, your fuel efficiency can only go down. The air filter will get dirty and make the engine less efficient, parts will begin to wear, etc. This is true of all normal cars.
