When choosing between a diesel and gasoline car, you should consider the advantages of each. Diesel engines became popular in passenger cars during the gas crisis of the 1970s, mainly because they offered better fuel mileage than gasoline engines. Although their popularity has diminished, diesel engines are still available on some imported automobiles. Newly designed diesel engines are 30 to 50 percent more fuel-efficient than gas engines. They don't require tune-ups and last two to four times longer than comparable gas engines, but there are several reasons why gasoline engines are more popular in today's cars. Gas engines cost less to buy because they don't need the heavy-duty parts of diesels. Also, they run much cleaner than diesels, greatly reducing noise and smell. While a gallon of fuel costs about the same for diesel or gas, gasoline is easier to find. Gas engines also offer better overall performance and pickup with less vibration. If comfort and convenience are a high priority, your best bet is probably a gasoline engine. If you require a heavy-duty, durable vehicle with hauling capabilities, a diesel might be your best choice. For more information on diesel and gas engines, consult your owner's manual or an auto dealer.
