What should i keep on at all times the 2wheel drive or Auto for a 2006 Chevy Trail blazer?
Keep it in 2WD at all times. Only on snow covered roads should you leave it in 4WD. If you leave it in 4WD on dry pavement, it will really raise holy hell with your tires and drive train. As long as roads are wet,slushy snow, 4WD will be fine.
