In 2012, NHTSA and EPA extended Corporate Average Fuel Economy (CAFE) standards for light duty vehicles through the 2025 model year. The new standards require passenger cars to achieve an average of five percent annual improvement in fuel economy and light trucks to achieve three percent annual improvement. This regulatory requirement to improve fuel economy is driving research and development into fuel-saving technologies. A large portion of the current research is focused on incremental improvements in fuel economy through technologies such as new lubricant formulations. While these technologies typically yield less than two percent improvement, the gains are extremely significant and will play an increasing role in the overall effort to improve fuel economy. The ability to measure small, but statistically significant, changes in vehicle fuel economy is vital to the development of new technologies.

As the U.S. Military considers fuel sources around the world and into the future, fuels produced via non-conventional means are anticipated to become increasingly available and of growing importance. One such type of fuel, a synthetic fuel, can be produced from conversion processes employing Fischer-Tropsch (F-T) synthesis and starting with natural gas, coal or biomass feed stocks. The Single Fuel Forward (SFF or single fuel in the battlefield) policy requires the use of JP-8, JP-5 or Jet A-1. Evaluations of F-T fuels, such as synthetic JP-8, in military ground vehicles, aircraft, associated equipment, and fuel storage and distribution systems is needed to assess ability to meet desired and/or required operational performance and to identify potential issues, as well as potential benefits, with the introduction and use of these fuels.
