What type of fuel does the M998 (HMMWV) use?

The M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV) is designed to operate on diesel fuel. This type of fuel is advantageous for military vehicles due to its efficiency and the higher energy content per gallon compared to gasoline, resulting in better performance and range. Diesel engines are also generally more reliable for heavy-duty applications and provide increased torque for off-road and rugged terrain capabilities, reflecting the HMMWV's role in versatile military operations.

Using diesel fuel allows the HMMWV to maintain effective operation in a variety of conditions, making it a preferred choice for military logistics and transport. The adoption of diesel fuel also aligns with the military's logistics framework, which emphasizes the need for interoperability and compatibility with supply chains.

In contrast, options such as gasoline, propane, and ethanol do not align with the established design specifications and operational requirements of the HMMWV, which was intentionally built to use diesel for its unique qualities and advantages in military applications.
