Aftermarket Retrofit Device Evaluation Program

EPA conducts a voluntary program to evaluate aftermarket devices and fuel additives that manufacturers claim will improve fuel economy and/or reduce exhaust emissions for passenger cars and trucks. The purpose of the Aftermarket Retrofit Device Evaluation Program (also known as the "511 Program") is to generate, analyze, and disseminate technical data on the effectiveness of such products. This web page provides information for manufacturers on how to have a device evaluated, along with information for consumers interested in such products.

IMPORTANT REMINDER: EPA does not approve, certify, endorse, or register any products that pass through this voluntary evaluation program. Neither does EPA approve, certify, endorse, or register any independent laboratory or the test results from any independent laboratory. Any claims by a manufacturer to the contrary are false.
