Tested by the onboard computer and by the old fashioned way. the onboard computer is within about 1/10 mpg. I don't know the highway mileage since I still haven't taken any kind of a long trip in this Tahoe.

Thanks for the replies guys. I am not to concerned about gas milage I was just curious. I would like something slightly better than my 00 Silverado 5.3 4wd (13-15). I would mainly be driving highway (75%) and those numbers arent bad. Its in the middle between my truck and impala. I have flexfuel available not sure on current prices. I did find the perfect tahoe recently on a dealers lot but I wont seriously look until later this summer probably an 08 model? Also are you able to get a 2wd LS model with a sunroof? All the sites I have been on do not have this as an option |

Replying to: 4speed1 (Feb 18, 2007 10:02 am) Do you do all of your driving downhill? I also have the 2wd and 5.3 flex fuel engine and averaged about 15.5 mpg over the past four or five tankfuls. Of course, most of my driving was short trips  speeds of 40 mph or less, although there was some freeway driving mixed in there. The only "all day trip" miles I've put on my Tahoe was just after I turned over 1,000 miles, from LA to Houston over three days and averaged about 16.5 mpg. I wrote that off to not really being broken in yet and hope for bettter next time I take it on a long trip. Currently I've got about 6500 miles on it. I do see it drop down to 4 cylinder operation a lot, if I remember to keep a rather light foot on the gas, so that feature seems to be working. I'd also like to see some other responses on what kind of mileage people are getting. Thanks.

Replying to: dmyer3 (Feb 19, 2007 4:51 pm) My wife drives our 07 LTZ (5.3L with 3.73's) about 95% of the time...And the best I've seen so far (had it 11 months now with about 13K miles) is around 15.5. This is almost entirely city / around home driving with little to no highway miles. Not too bad I guess beings the sticker states 16 MPG in the city.....

Replying to: csprick (Feb 19, 2007 3:31 pm) --CRUISE CONTROL --Not racing up to red lights like 99.9% of drivers do. Always amazes me how many people are in a hurry to get to a red light. --And drive quite softly overall. I also go the speed limit--rarely go over 70--usually do 60-65 mph. My hot-rodding day are past me. I already set plenty of land speed records and have the tickets to prove it. But I have had it up to 90 -100 mph a fews times  Most people do not use cruise control, but it makes a hell of a difference. I know this because I see people varying their speed all the time while mine is constant. I used to have a 99 Tahoe 2 door, and the most I ever got out of it was about 17mpg with the same driving style I have now. This 07 tahoe is a much better motor with more power too. The Tahoe will run in 4 cyl mode as long as your going under 70 (level road). At 55-60/mph it will run in 4 cyl mode even on slight hills. This definatly helps the MPG. But I see people passing me in their 07 Tahoes all the time doing 80mph-----so I guess that's why you got people on here complaining about mpg's. Now I wish the Tahoe had a 5 speed manual transmission---That would be cool. Why doesn't Chevy do that?

Replying to: 4speed1 (Feb 19, 2007 7:38 pm) I live north of Houston about 6 miles from the nearest highway - lots of stoplights between me and a 60 mph road. A lot of my travel is local streets, i.e., non-highway, with max SL of 40-45mph. Once I do hit a highway (and a lot of them here in TX are two lane or four lane undivided), the traffic is usually heavy and traffic speeds vary so much that using the cruise control seems pointless. Like you, my speeding days are mostly past and I also try to drive "soft". The old recommendation about pretending there is an egg between one's foot and the pedal does help improve the mileage. I'm hoping the mileage will improve as I get more miles on my Tahoe. My observations regarding the 4 cyl mode is pretty much like yours; however, I wore out my left leg shifting a manual transmission in a Nissan 4X4 while commuting 50 miles a day on Hwy 101 through Silicon Valley a few years ago. I got my fill of "freeways" in the San Francisco Bay area and for the past five years commuting to downtown LA. God Bless Texas!
