We gave our daughter my old car (2003 Chevy Malibu) to drive to school and work and pleasure. I'm finding that I got better gas mileage than what she does. I know one factor is that when she drives up to the school (which is a lot even during the summer) we only live about 2 miles from the school not giving her car time to warm up. What can be done to help get better mpg for her? Her other frequent traveling is to work and she works about 10 miles from our house. Just looking for suggestions.
