Fuel Saving Tips
If you regularly have several choices of gas stations, compare stats over several fill-ups. For example, my local full service Shell is usually 2 cents more expensive than the other off-brand station. Yet I found my fuel economy was 5-10% higher (lower? - more miles for the buck) with the full service Shell. I've mentioned my results to several of my friends, who have found the same increase over several months of checking. Although this runs contrary to common thinking, the numbers here have proved differently. Your mileage (literally) may differ.
