I asked my wife to take my car to great canadian for a lube and oil change,I didnt ask her to get the engine flushed but they forced my wife to have it done,I just had it done 3 months ago.I am going to pay them a visit and ask them why they did this when it was not neccessary,just goes to show that great canadian push the women into getting things done that are not required...NEVER USING GREAT CANADIAN AGAIN
