I live in the Reno area and my 2015 Limited has averaged just a tad under 28 mpg (calculated by dividing actual miles driven by actual gallons of gas purchased since I bought the car new). I drive roughly 1/2 city and 1/2 highway miles. On the highway, with the engine completely warmed up, the onboard computer shows about 32-33 mpg for longer trips such as to Pyramid Lake and back, or between Verdi and Sparks. I usually maintain my tire pressures at about 3-4 psi over the factory recommendation. I also change my air filter and clean the MAF sensor once per year. I never let the engine fast idle from a cold start until the blue temp light goes off since that's a waste of gas and not necessary. I start the engine, let it run just a few seconds, then get going which is the best way to get a cold engine warmed up quickly.
