I get 17-18 around town and 22-26 on the highway with my 2018 2.5l 4wd with 11k miles.Hello everyone!
I have a 2019 Colorado WT Extended Cab with the 2.5 4 cylinder and 6 spd. auto. Recently, I've been averaging 15-16 mpg with combined highway and city driving. I only get about 240 miles to a tank. I used to get about 350. I never would have thought a small 4 cylinder truck would get this bad of mileage. In fact, I got this motor for the gas mileage perks, as the diesel was too pricey. Has anyone else had similar issues? I am trying to avoid another warranty trip to the dealer, so any help or feedback would be greatly appreciated!
