Diesel engines have been around for a long time and you would think the American automaker could design and build a good one, and they have, with two exceptions, the General Motors 6.2 and 6.5 iterations. When they came out with this one, there was not near enough testing done for aspects like longevity. It has been found that these auto engines are not capable of withstanding the high compression and torque a diesel produces.
The most common fuels in use today are made up of hydrocarbons and are derived from petroleum. These include the fuels known as diesel, gasoline and liquified petroleum gas. Most internal combustion engines designed for gasoline can run on natural gas or liquified petroleum gases without modifications, except for the fuel delivery components. Liquid and gaseous biofuels of adequate formulation can also be used. Some have theorized that in the future hydrogen might replace such fuels.
