Fact Sheet
AFTERMARKET GAS SAVING PRODUCTS AND
EPA PRODUCT EVALUATIONS
Aftermarket fuel additives and devices advertised to increase vehicle fuel economy
and/or reduce vehicle emissions may claim to have U. S. Environmental Protection
Agency (EPA) approval. EPA, however, does not approve, certify, endorse or
register these products.
EPA evaluates aftermarket fuel additives and devices on a voluntary basis when an
application is accepted from the company which manufactures the product. The
Agency may also evaluate a product at the direction of the EPA Administrator or
the Federal Trade Commission. Results of any evaluation are a matter of public
record and are published in the Federal Register. All preliminary independent
laboratory and EPA laboratory costs for a voluntary evaluation are paid for by the
company offering the product. The evaluation program is restricted to fuel
additives and devices and does not apply to oil additives and lubricants.
A minimum evaluation program employs the same type of scientific tests used by
EPA to certify vehicles for sale in the United States. These are the Federal Test
Procedure (FTP) and the Highway Fuel Economy Test (FIFET). Both involve
controlled driving patterns on a laboratory test machine (a dynamometer) which
similuates an actual road load condition and during which exhaust gases are
captured and analyzed. Fuel economy for city and highway driving (FTP and
FIFET, respectively) is calculated using a carbon balance formula and the actual
emission samples results which are the same methods used for calculating the city
and highway fuel economy information displayed on windows of new vehicles.
EPA tests are conducted under very controlled conditions in a laboratory to
eliminate uncontrollable variables such as individual driving habits, wind, weather,
traffic and road conditions experienced with actual driving on roads. The make,
model and year of vehicles used in an evaluation are selected to represent typical
vehicles for which the device or additive is intended to be used.
The test vehicle's engine is first adjusted to the vehicle manufacturer's
) Printed on Recycled Paper
-------
specifications and tested in this configuration to provide a base line. In the second stage the product is
installed on the vehicle and the test is repeated. In the third stage the product is removed and the vehicle is
reset to the original configuration of the first stage to determine whether use of the device affected
original performance. Duplicate tests are conducted for each of the vehicle configurations.
EPA engineers report their findings based on the test data. The report is then published in the Federal
Register. Individual copies of a test evaluation may be purchased from the National Technical Information
Service (NTIS).
EPA has evaluated over one hundred products in this program. A listing of the products which have been
tested (as of this publication's date) is attached to this document. The report number associated with each
of the evaluated products may be used to purchase a copy of the report. Orders for the reports may be
placed with:
The National Technical Information Service
5285 Port Royal Road
Springfield, VA 22161
Phone: (800)553-6847
It is suggested that individuals contemplating the purchase of these products request test data rather than
testimonial or anecdotal evidence from the supplier. One should also weigh the cost of the product against
the actual fuel savings over the intended use period.

(1) Indicated a statistically significant improvement in fuel economy without an increase in exhaust emissions although cost effectiveness
must be determined by the consumer for his particular application.
(2) Indicated a statistically significant improvement in fuel economy but with an increase in exhaust emissions. According to Federal
Regulations, installation of this device could be considered tampering.
