Thought I would post some gas mileage information on our 2016 Cheverlot Colorado driving back from L.V. SEMA show to Prescott Valley AZ. Our Colorado LT gas vehicle has the OEM 3.6L with Magnaflow exhaust Hypertech performance chip, Injen Technology cold intake, 20" RBP wheels, 6" @Rough Country lift, and a complete exterior Rhino Linings with UV coating. Driving between 65-72 MPH I ended up with 52.4 MPG. I'm sure some might find that hard to believe but it's a fact that was the mileage on our truck. I'm not a tech but I say pretty amazing considering all that we had done on this build. Now I guess that next step would be to find out how our Colorado performs off road....
