It is against Federal law for an original equipment manufacturer (OEM) to deny warranty
coverage based on the brand of lubricant used. The Warranty Secure symbol
informs consumers of this fact. Using AMSOIL synthetic lubricants in place of OEM-branded
lubricants, or practicing extended drain intervals when using AMSOIL lubricants,
does not void new vehicle or equipment manufacturer warranties.
According to the Federal Trade Commission:
The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty
or deny coverage under the warranty simply because you used an aftermarket or recycled
part.... The manufacturer or dealer must show that the aftermarket or recycled part
caused the need for repairs before denying warranty coverage.

AMSOIL stands behind its products and the people who use them. If the OEM claims
use of AMSOIL products violates the warranty, contact AMSOIL Technical Services
(715-399-TECH). For complete information on AMSOIL warranties, contact AMSOIL Technical
Services or visit www.amsoil.com/warranty.
