Everything is stock. I am going by the DIC and I have not had the diff or transfer case fluids changed (to my knowledge). i bought the vehicle with 36k on it about 4 months ago.- xzzzzzzx

2009 Tahoe LT Z71 V8 5.3 flex MPG?
I have a 09 tahoe z71 v8 5.3 with 38k miles using 87 octane fuel and I am seeing around 10.5mpg and 14-15mpg on the highway-long trips...Is this normal? I think the city should be higher. No mods and normal driving conditions. 4wd set to 2wd (not auto). Any suggestions on how to increase?- xzzzzzzx
