Gasoline-powered engines are the most common engines found in consumer automobiles. In comparison to diesel-powered engines, gasoline-fired engines produce fewer environmental pollutants, create less vibration and noise, and are lighter in weight. They are also easier to refuel, thanks to the greater availability of gasoline fuel in the United States as of 2014 and are less likely to create problems with vehicle starting in cold weather. These engines are not perfect, however. The price of gasoline varies, and it may be expensive for some drivers to keep their gasoline-powered cars on the road. Additionally, bad fuel mixes may seriously impair engine performance and cause permanent, irreparable destruction. Furthermore, although gasoline engines have higher power ratios than their diesel-operated counterparts, they often have shorter lifespans.
