Alright,
I am a newbie here but i want to put my two cents in after i saw Big John is from Santa Fe, i'm just a lil north of him and i have a 2005 Envoy XL. I get about 25-29 mpg!!! And i thought this mpg sucked, lol. This is no mistake, i check the mpg everytime i put gas, don't forget i put the premium gas, no cheap stuff, cuz i will get about 20-22 if i put bad gas in thurrr.
