If your vehicle is equipped with a tachometer,"train" your accelerator foot to try to keep the RPM's below 2500...My younger daughter WAS very heavy-footed and, she always whined about her MPG... Since I showed her this simple hack, her mileage went up on 10%...It also saves a lot of wear and tear on your drive train...Now we like to 'compete' over who is getting better mileage
