With a good tune up the wifes 97 4door blazer, 4x4, 4wd gets 17.5 mpg (city).. right now with a bad 02 sensor its getting 15mpg. Not sure on the highway but plan on taking it on a road trip in Mid July so we will see.. I am ready to get rid of this thing though. My 91 Jeep Cherokee 2 door, 4wd, 4.0 ltr inline 6, with 5 speed gets 20 mpg (city). Not sure on the highway, and I dont even use 5th gear. Looking for an Auto 4door 4wd Cherokee for my wife, 20 mpg isnt the best obviously, but it is better than 15-17 and I have had too many problems with the blazer.
