Originally posted this in an apparently inactive suburban forum...

Looking at the specs and at fueleconomy.gov, the 2006 model year's mileage is less than both that of 2005 and 2007. I'm wondering if I should avoid looking to purchase a 2006 because of this? Does the engine have some flaws that were introduced in 2006 and fixed in 2007? I know this is some pretty specific info, but I figured if anyone knows, that person will probably see this

TIA,

Russell

Yeah but that started in 08 and I am comparing mileage from 05 to 07. Aren't mileages self-reported by the manufacturers?

Default Mpg

no, the EPA estimates them...

if the MFG did, they would all say 200mpg

the 07 tahoe is WAY different than the 05...

if you are concerned with a few MPG, a Tahoe or Suburban is not the vehicle for you...

It hauls people and trailers. If you want MPG you need a sedan / volt / accord/ etc.

Default 2011 mpg

My 2002 tahoe got 16 continously the new one gets around 15 even with the 6 speed and the crappy 4 cylinder stuff. Looking for a chip that disables the 4 cyl, any suggestions?

I absolutely agree, my main concern is not the actual mileage but rather whether or not the engine or other components had some engineering defect in that year that might cause premature failure. I don't want to buy a vehicle that I know to be problematic!

The only info on differences between 2005 and 2006 that I could find is this, from wikipedia:
The catalytic converters were relocated closer to the engine, allowing for faster "light off" and reduced emissions.

I suppose comparing to the 2007 is not apples to apples since the body style changed.

Just drive it hard enuf so it never goes into 4 cyl mode.

Mine gets about 12-13 in town and 18-19 on hwy at 75. These are actual calculated values, not DIC. At 60 on level hwy, the DIC says 21-22 in 4 cyl mode. Mobil 1 also.

Moral is if you want good mpg in these 2.5 ton beasts, you can't drive it like you stole it.

I agree if you're looking at a burban or tahoe you mind as well throw out all that economic BS that everyone is worried about nowadays. My 94' burb get's 10 MPG so if you're worried about getting like 16 I'll trade you. :]
