Prior Year Surveys are also available for purchase.

The Alliance North American Fuel Survey© (NAFS) has been conducted twice per calendar year (sampling conducted in January and July of the calendar year) for over 20 years, to evaluate fuel quality of commercially available regular and premium motor vehicle gasoline, and diesel fuel.

The reports are sold subject to the terms and conditions of the Alliance Limited Licensing Agreement and Guidance for Use document.

5th Edition Worldwide Fuel Charter

Recommended Automotive Fuel Specifications – Available FREE

The Alliance of Automobile Manufacturers, along with the Truck and Engine Manufacturers Association, the European and Japanese Auto Manufacturers Associations, and automakers around the world, proudly announces availability of the 5th edition of the Worldwide Fuel Charter, which is being made available for free from the Alliance (available in 1 page or 2 page formats).

The objective of this global fuels harmonization effort is to develop common, worldwide recommendations for quality fuels, taking into consideration customer requirements and the performance of vehicle and engine emission technologies. These recommendations allow vehicle and engine manufacturers to provide consistent fuel quality advice to fuel suppliers and policymakers on an international basis. These recommended gasoline and diesel fuels will benefit consumers and their communities in all markets around the world.

Implementation of the recommendations will:

  • Reduce the impact of motor vehicles on the environment by enabling reduced vehicle fleet emissions;
  • Facilitate the delivery of optimized fuels for each of five vehicle technology/emission control levels, which will help simplify vehicle equipment and help reduce customer costs (purchase and operation)
  • Increase customer satisfaction by maintaining vehicle performance for a longer period of time.
  • In addition to the Gasoline and Diesel recommendations, technical background discussions are provided, along with responses to public comments received on the final draft document.
