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 warranties
or deny coverage under the warranty simply because an aftermarket or recycled part was used.... The manufacturer or dealer must show that the aftermarket or recycled part
caused the need for repairs before denying the warranty claim. (http://www.ftc.gov/bcp/edu/pubs/consumer/alerts/alt192.shtm) (emphasis added)
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).
