This lesson was a very brief overview - there are entire classes based on this one lecture. In this lesson, we discussed the different transportation engines for vehicles, the fuels used for these vehicles, and how the fuels are produced from a refinery. Gasoline is the lighter fuel used in typical automobile engines, while diesel fuel is used in Diesel engines. Diesel engines get better fuel mileage than gasoline engines - gasoline is lighter than diesel. Here in the US, the primary fuel produced is gasoline (~45-50%).
