I have 18K on my Eco, this is my second one, I traded in a 14 for the 20. I have never reset my trip computers from the day I bought it and it indicates that my average is currently 28.4. I don't do a lot of towing. Most of the time it is for short trips since I am recently retired. I do use it for 300 mile trips a few times a month and have made a 4800 mile round trip to California and back. I have not had any issues what so ever with it. Getting ready to get my second oil change and the fuel filter change. Then another trip to Colorado.
