HAH. my tahoe would get me way below 10mpg before i sold her recently. 1996 chevrolet tahoe, 221k miles, 4x4. 75% of the engine was OEM and the transmission was 100% OEM, til i sold her recently. owned by 2 gm mechanics and my father then me. i spent 500 a month on gas, i make 1500.... 33% straight to gas. that was 4 years of my life and a few tears later, and my first car was gone.... its tough but it was an angel of a vehicle. that aside, deal with the shit MPG its a great truck.
