I'm curious... I have a 200 Tahoe Limited with K&N filter, Flowmaster muffler and throttle body spacer. During the Winter months, my MPG is 18-18.5 MPG. During the Summer, it's been around 16-16.5 MPG.

What is the MPG on your Tahoe/Yukon?

The BEST I have ever seen my 98 Tahoe get was 15.5, and my average by now is 13ish. Since I bought it I have put bigger Tires (-1 mpg), Synthetic oil (+1 Mpg) a new PCV valve and a K&N drop in air filter (combined +1Mpg) and im still only at 13 tops!

With 130+ views, I am unimpressed with only 18 votes!!! come on guys and gals, we all know these things are gas hogs, but share with us your results; or is it that you are getting below 13MPG, I'll be honest, I tend to get around 12!

Managed almost 14 mpg driving from central Texas to NY during one leg when I didn't have to use A/C (over $300 in gas for that trip). Otherwise, usually around 11-13 depending on type of driving. I've got nine inches of lift and 35" tires on this thing, so i'm not too disappointed.

Mine is a 99 and the best ive got on a trip was 16 mpg, but most of my driving is around town type and probably doesnt get better then 13 or so for the majority.

Tried the perf. tuning on mine a few months ago, no improvement in mileage and made the engine knock (yes, I put in the highest octane, even tried booster, and still knocked). So I just reset it back to 87.

And one more note, if someone (i.e. muffler shop owner) tells you to put in a muffler with more back pressure (as opposed to cats only or a fiberglass packed muffler) to get improved gas mileage...this doesn't work from my experience. I had no muffler on mine and was talked into a flowmaster or something like that. No better gas mileage and my tahoe sounds like a wimpy racecar now.

I get up to 17.5 MPG on the freeway and around 13 MPG around town. Freeway MPG is based on getting 365 miles or so on a fillup of 20.5 gallons. I use 91 fuel. Truck is bone stock.

Can't resist... 22 mpg highway but that's on a 6.5td 2dr 4x4 (stock except for K&N drop-in air filter which I've wrapped with about ten feet of surgical gauze and sprayed with K&N filter oil to act as a pre-filter); 30 gal tank.

I'm new to this forum but I've been a Tahoe owner for four years and you might say I'm a bit anal b/c I have actually tracked MPG for EVERY single tank of fuel that I've put in my truck since I bought it used in September 2000. Here are the stats:

Vehicle: 1997 2WD 4Door LT Tahoe
Mods: Not much - K&N Air filter, Edelbrock struts, Borla cat-back dual exhaust
Tires: 235/75/15 Bridgestone Duellers until recently I switched to new 255/70/15 Firestone Destination LE's
Miles Driven - 53,297.8 since I've owned it
Gallons - 3,422.1
MPG Average - 15.57
Average price per gallon - $1.36 (87 octane)
Cheapest price per gallon - $0.92 per gallon on 11/31/2001
Most Expensive price per gallon - $1.87 per gallon on 05/27/2004
Best tank of fuel -
Worst tank of fuel - 12.62 MPG, January 2004
Best tank of fuel - 18.48 MPG, August 2003
Most gallons squeezed into the tank - 28.761 Gallons on 1/19/2001 (yea, I'm thinking I had to be pretty close to empty there!)
Truck mileage today - 132,500 miles

We just bought 1996 2wd Tahoe last Friday. Clean truck with 119k. The previous owner installed a power chip, flowmaster and K&N drop-in filter. Our first tank full got us 13 MPG. That was 30% city and 70% freeway. I am thinking about replacing the cat converter jest because it is close to 120K. I feel we shoiuld be getting around 15-17 MPG.

13-15mpg before I started driving my truck like a cruiser. My tank went from 285 a tank up to 330-340. I am sold on taking off easy at the light and trying to keep it under 2g rpm's until OD kicks in. :naughty:

Hey bartlanz whats up with the emergency flasher? Are you another one of those EMT's or Paramedic that has to use there own vechicle? I would tell LAcoFD to shove it, if we had to use our personal vechicles.Although Whelen makes a great unit so does Federal Signal.

Had my 2000 limited brand new. Drove stock for around 2yrs. Avg. 14-17 city and hwy. Put Flowmaster 50 series added around 0.5mpg. ~6mos ago put on K&N FIPK II. Mostly drive highway and have been averaging 18-21 mpg. Probably the best $250 spent.
