What is the difference between gasoline and diesel engines? Beyond requiring a different fuel, diesel engines are quite different in design and have different needs and requirements when being serviced. Add to this that diesel engines are put to the test in hard-working vehicles like buses, large trucks, and equipment used in agriculture and construction, and it’s no surprise you need a specialized technician to work on them.
