I'm close to making a deal on a slightly used '09 Tahoe LTZ with the 6.2L (395 HP) engine and 6 speed transmission. I've currently got an '03 Tahoe with the 5.3 and I am used to poor mileage. Will the 6.2 mileage be much less? When I test drove it I checked the trip meter for average MPG and it was a bit higher than the average on my '03. The LTZ is a nice package with lots of buttons. Are there any other issues I should be concerned about.
Thanks,
Dennis
