OU'RE INTERESTED IN AMSOIL motor oil, but
concerned that using a synthetic oil or extending your oil
drain interval will void your warranty.
You have no need for concern. Congress in 1975 enacted the
federal Magnuson-Moss Act to regulate written consumer product
warranties. An examination of the law reveals warranties remain intact
when AMSOIL Synthetic Lubricants are used.
The law was meant to give consumers detailed information about warranty
coverage before they buy.
Congress charged the Federal Trade Commission with creation of the
specifics of the law.
The FTC set down three rules under the Act: the Disclosure Rule, the
Pre-Sale Availability Rule and the Dispute Resolution Rule.
Those rules require warrantors to title their written warranty as
either “full ” or “limited,” provide a single,
clear and easy-to-read document that spells out certain information
about coverage and ensure that warranties are available where the
products are sold so that consumers can read them before buying.
In passing the Act, Congress meant to give consumers access to warranty
information, let consumers comparison shop for warranties, encourage
warranty competition and promote timely and complete performance of
While the Magnuson-Moss Act does not require manufacturers to provide a
written warranty, it provides specific rules when one is provided.
Among those provisions, FTC regulations state: “(c) No warrantor
of a consumer product may condition his written or implied warranty of
such product on the consumer’s using, in connection with such
product, any article or service (other than article or service provided
without charge under the terms of the warranty) which is identified by
brand, trade, or corporate name; except that the prohibition of this
subsection may be waived by the Commission if – ((1)the warrantor
satisfies the Commission that the warranted product will function
properly only if the article or service so identified is used in
connection with the warranted product, and (2) the Commission finds
that such a waiver is in the public interest.” ((42
That means your warranty stands when you use AMSOIL Synthetic
Vehicle manufacturers recommend lubricants according to their viscosity
grade and service classification. Any oil, whether it ’s
conventional petroleum motor oil or synthetic, meeting the correct
viscosity grade,5W-30 for example, and the current API SL and ILSAC
GF-3 North American service classifications may be used without
affecting warranty coverage. AMSOIL motor oils are recommended for use
in applications requiring these specifications.
Furthermore, the practice of extending oil drain intervals does not
void warranties. Original equipment manufacturers pay or deny warranty
claims based on the findings of failure analysis. To affect the vehicle
warranty, the lubricant must be directly responsible for the failure.
If the oil didn’t cause the problem the warranty cannot be
voided, regardless of brand or length of time in use.
Synthetic motor oil was introduced to the automotive public in 1972 by
AMSOIL, INC., with the world ’s first API rated synthetic motor
oil – specially formulated for long service and superior
performance and protection to that of conventional oils.
Nearly 30 years ago, AMSOIL synthetics represented a vision of the
future and technology ahead of their time. Since then, every major
engine oil manufacturer has introduced synthetic oils of their own. To
be sure, many original equipment manufacturers would like you to
believe you can only use their products. However, it ’s a
violation of the consumer protections set forth in the Magnuson-Moss
Act, unless they ’re willing to provide you those products free
AMSOIL offers a warranty that covers the cost of repair or replacement
of a proven mechanically sound engine damaged as a result of using
AMSOIL synthetic motor oil. However, it has never happened. Thirty
years of experience proves AMSOIL can be installed in any mechanically
sound vehicle with complete confidence.
AMSOIL further backs its products with action when a Dealer or customer
reports being told their warranty is voided if they use synthetics.
* Note: If a car or truck dealership, service center or other business states
that using AMSOIL motor oil in your vehicle will void your new vehicle warranty,
ask for that statement in writing and send it to AMSOIL Technical Services.
If the business won't provide the statement in writing, send AMSOIL Technical
Services a letter identifying who made the statement, the name and location of
the business, and the statement made, to the best of your recollection. AMSOIL will
then send a letter to the business informing them that their position is
inaccurate, and, in fact, violates existing law. Your personal information will
be held in confidence.
