My truck has a fuel avg readout among the many many other readouts. I filled the tank and ran it down fuel avg was not lying, 10.2 mpg avg. Yeah the real-time mpg display option wildy fluctuates sometimes showing 60mpg... but thats 4cyl going down hill with strong wind at my back Thanks for the advice, I thinks its the fuel composition sensor that needs resetting especially since winter is now here. High alcohol content in most fuels = bad gas mileage and malfunctions... Aloha and Mahalo Timothy

Great information! I suspect it's something like that! It really is only getting 10 mpg city flatlands, filled tank and proceeded to only get 220 miles on that full tank, so the milage tracking software is not lying about fuel usage... Not too many downhill areas where I can get that 60mpg fuel savings, have to climb up that hill to go down it again.......... Truck runs absolutely strong, however gas at +$4.00 gal is a real bumski. Thank you for the advice, and nowmhow to remedy the situation? Im not a mechanic nor do I even have a garage to work on the truck. Thank you again, happy holidays Timothy

Thats great information/observation thanks for passing that along! Yeah those fender flares I had a suspicious feeling were the cause of my fuel consumption woes! Maybe a very narrow two track can sort that issue out! With all that being said, we're in the Midwest and it's pretty flat around here so it's not a lot of hills that's causing the issue. It definitely could be the gearing! like I said the truck is very lively with the 5.3 l V8 power plant, I have not done the research to see if my vehicle will run flex fuel there are no placards nor decals on the truck saying that it will run e85 I don't know if I want to even do that though because that high alcohol content in the fuel is hard on engines and I would like to get as many miles out of this thing that I can considering the price I paid. I basically got the truck for half price it being 9 years old with 152,000 mi on it, with the window tints and other fancy schmancy accoutrements the thought crossed my mind that it could very well possibly be a former cartel member personal ranch vehicle? Ha! Anyways, thanks for the advice the fenders came on the vehicle, I guess I could always remove them and gain 10 more miles per gallon (if it really were that easy!) Bwahahahahahahahahaaaa! Blessings snd Aloha

Terrible fuel economy Truck runs lovely and lively. Data on readout shows 10.2 mpg avg thought my gas gauge was going down rapidly and that someone was stealing gas out of my tank at night haha so I went looking and found the readout for fuel average and saw that it was saying 10.2 miles per gallon. Are they really that big of gas hogs? Now this is mostly City driving, Virtually little highway driving should I take it to the Chevy dealer and have them do a tune-up? I figure that will be quite spendy, actually what I need is a good mechanic in my area who works on GM trucks honestly and with pride of a job well done. I bought the truck used from an outfit called motor Max I've had the truck for a couple of weeks and have literally only driven maybe 200 miles since then and I've gone through almost a whole tank of gas I'm flabbergasted at how much fuel has been used so any and all wisdom will be considered thank you in advance Timothy
