#3 of 10 How to improve gas mileage
Feb 27, 2010 (6:39 am)
I just bought a preowned 2005 Envoy SLT and it gets 15 mpg in the city. Any ideas on how to improve mileage (new tires? better gas?). Shouldn't it get around 20 in the city?

not sure how to improve. but my avg is closer to 17; that's based on 90% around town.

Yes. I think it should get at least 18-19 as does mine (2004 SLT). start by changing the fuel filter and check for any codes, you may have a lazy o2 sensor.
Thanks and good luck

currenly having issues with my 4x4. I have replaced the TCCM switch and also the motor, and it will still not engage. The "service 4wd light" is on all the time. I was having some battery issues when this all started about a year ago. Any thoughts???

I had a problem on my 2005 envoy with a service 4wd light what it turned out to be was a wire that was almost rusted in half once the mechanic found it he had to replace about an inch of wire and it is working fine now.

Good luck, bought mine new in 06 and it still gets only 17.5 average! Fuel not so bad to me as the problems I am having with it. It is basically a piece of junk!
#9 of 10 More Envoy problems

I got my gas gauge of my 06 Envoy fixed a few months back..now the check engine light stays on! The dealer wants a fortune just to diagnose problems and the price per hour for labor is not something I can afford...yet they will not refund you anything on the gas gauge repair unless you take it to a certified dealer!! GM should be ashamed after taking all the bail out money!
The truck now makes some kind of noise when it is cold. It seems to be coming from the transmission. We put a new water pump on it this summer. It seems there is ALWAYS something going on. I thought when I bought this truck new and for the price I paid , it would last me a long time. It has a little over 100k and began having problems at about 75k. I WILL be getting a Toyota next time around..enough of government motors!!
