Monjapino, Its my belief that most of the Aveo owners you will interface with on this forum are from the U.S.A.There is a contingent from Canada and Latin America also, but all are welcome. A factory-installed diesel Aveo is a very interesting concept from the standpoint of economy and duration. Would you please post a pic of your 2011 LTZ and a shot or two of the diesel power plant? Also,is your Aveo a sedan, 5-door and what transmission is hooked to the diesel? Welcome and good luck!
