Warranties and Amsoil

Virtually all automobile manufacturers warrant their vehicles to remain free of defect in manufacture or workmanship for a certain mileage or time period. Whether an automaker will honor a warranty claim depends on the vehicle owner providing proper maintenance for the vehicle.

For this reason, it is important for vehicle owners to maintain maintenance records. Proper maintenance includes installing appropriate
oil and filters.

Automakers cannot deny warranty claims solely on the basis of using synthetic motor oil, and they cannot specify a certain oil brand to be used in their vehicles. Instead, they require the oil meets the appropriate API performance classification and SAE viscosity grade specified in the owner's manual.

"Installation or the use of special materials does not, in and of itself, void the New Vehicle Limited Warranties." Service and Parts Operations, Chrysler Corporation

Many high performance vehicles are factory filled with synthetic motor oils and the manufacturers encourage continued use of synthetic motor oils in order to achieve maximum performance, including Cadillac, Chevrolet Corvette and Dodge Viper. Many other automobile manufacturers neither recommend or discourage the use of synthetic motor oils, requiring only that the oil meets a certain viscosity grade and performance classification.

Automakers may not void warranties based solely on an owner's practice of extending oil drain intervals. Dealership personnel and district managers may be unaware of the serviceability of synthetic oils over an extended period, but they may not summarily dismiss a warranty claim based on the owner's practice of changing oil at extended intervals. To do so does not disprove a defect in manufacture or workmanship as the immediate cause of failure. Vehicle owners may appeal to a factory representative if the dealership and district manager do not satisfactorily settle the warranty claim. Factory representatives appreciate the value of used oil analysis and do consider preventive maintenance oil analysis reports in their evaluations of warranty claims, while post-failure oil analysis is critically important to the disposition of a warranty claim. Their findings pull more weight than the opinions of dealerships or district managers.

"If engine damage otherwise covered by warranty was found to be unrelated to the engine lubricant, then the consumer's practice with regard to oil change intervals would not be a relevant consideration, and the warranty claim would be honored." Fuels and Lubricants Division, General Motors Research Laboratories

If used engine oil is discarded without an independent analysis, the dealership and vehicle manufacturer lose their evidence to support a claim that the oil, and not a mechanical problem, caused the failure. For example, sludge may be formed through several avenues, not all related to the oil's performance. Antifreeze contamination or nitration due to poor electronic sensor performance may cause sludge, and both may be directly related to a defect in vehicle manufacture or workmanship, but clearly neither may be blamed on the oil.

"The New Vehicle Warranty would not be void simply because an owner failed to use proper engine oils or did not perform maintenance at the prescribed intervals. Warranty applicability is contingent upon the cause of failure." Service Policies and Procedures Department, General Motors Corporation

Vehicle manufacturers base their owner's manual maintenance recommendations on their own research and to best protect their equipment based upon lubricants of varying quality, reliability and value in the marketplace. A move toward extended drain intervals is in progress now. Ford recently extended its recommended drain interval to 7,500 miles in normal service conditions, while GM has been recommending increased intervals when indicated by its oil monitoring system.

AMSOIL offers superior synthetic motor oils fully capable of providing extended drain service. AMSOIL is committed to backing its products, as well as protecting the interests of its customers. Therefore, AMSOIL INC. offers its customers a warranty.

"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."

AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.

Warranty Specifics
Any lubricant meeting viscosity and performance specifications may be used.
Vehicle manufacturers describe lubricants by their viscosity grade and service classification, which are defined by the Tripartite Committee, composed of the American Petroleum Institute, the Society of Automotive Engineers and the American Society for Testing and Materials. All AMSOIL synthetic motor oils state their SAE viscosity grade and API performance classification on the product container, and all are recommended for the highest performance classification for their application.

If personnel at a vehicle dealership claim that a vehicle warranty is void simply by using AMSOIL synthetic motor oil, obtain this statement in writing and send a copy to AMSOIL INC. AMSOIL INC. will follow up with the dealership.

The vehicle manufacturer may not specify by brand name the products you may use in your vehicle.
The Magnuson-Moss Act is a federal law which states that a manufacturer may not require the use of a specific brand of aftermarket product, including lubricants, unless that part is provided by the manufacturer free of charge. To do otherwise constitutes an infringement upon free trade.

If any representative of the vehicle dealership or manufacturer informs you that you must use a specific brand of lubricant or filter, obtain a written statement to that effect and send a copy to AMSOIL INC. AMSOIL will follow-up.

Cause of failure is paramount to warranty claim payment.
Vehicle manufacturers warrant their products to be free of defect in manufacture or workmanship. In order to avoid paying a warranty claim, a vehicle manufacturer must show a failure is not due to a defect in the manufacture or workmanship of the vehicle. The manufacturer may not arbitrarily blame a failure on the consumer's practice of changing oil at extended intervals.

Verbal notification of refusal to honor a claim is insufficient.
The refusal must be in writing and must state the specific reason a claim has been refused. If you still think a failure is due to a defect in vehicle manufacture or workmanship, contact the dealership, district manager, manufacturer or arbitrator.

The AMSOIL warranty assumes protection where the vehicle warranty stops.
AMSOIL offers complete protection to its customers through the finest line of lubricants and filters available and through the unique AMSOIL warranty. Customers following AMSOIL recommendations are protected by the AMSOIL warranty if they experience a failure caused by an AMSOIL product and the vehicle manufacturer won't honor its warranty.

Customers are Covered
As long as customers maintain their vehicles properly and follow either the vehicle manufacturer recommendations or AMSOIL recommendations, their vehicles are warranted against failure by either the vehicle manufacturer or AMSOIL INC.

Document #AMSOIL Warranty
Download the AMSOIL Warranty in PDF Format  

AMSOIL INC. warrants each AMSOIL filter to be free from defect in material and workmanship during the period of service life recommended by AMSOIL INC. or the engine or equipment manufacturer. This warranty may not be extended to cover AMSOIL filters that have been improperly installed, abused, damaged or used in competitive racing or on equipment that has been modified using components other than those from AMSOIL or AMSOIL aftermarket partners. AMSOIL INC. does not make filter recommendations for aircraft or aviation applications and does not guarantee the performance of AMSOIL filters in such applications. If an AMSOIL filter is found to be defective in material or workmanship during the period of service life recommended by the engine or equipment manufacturer or per AMSOIL recommendations, AMSOIL will replace the defective filter with another AMSOIL filter or credit the customer’s account. AMSOIL will reimburse the customer for reasonable costs of parts and labor required to repair the engine or equipment to the extent the damage was solely attributable to a defect in the AMSOIL filter.

In order to obtain engine or equipment repairs under this warranty the customer must contact the AMSOIL Technical Services Department directly at:

Attn: Technical Services Department
1101 Susquehanna Ave.
Superior, WI 54880
(715) 399-TECH (8324)

The customer must also allow the AMSOIL Technical Services Department to examine the filter and, if required, the engine or equipment to determine the extent of damage and whether it was caused by a defective AMSOIL filter. The filter must be returned in its original, undamaged condition to the AMSOIL Technical Services Department for examination. This warranty is exclusive of any other warranty, expressed or implied. AMSOIL filtration products expressly disclaim, without limitation, the implied warranties of merchantability and fitness for a particular purpose. The foregoing states the entire AMSOIL filtration products exclusive liability and the buyer’s exclusive and sole remedy for any damages or claim made in connection with the sale of an AMSOIL filter. AMSOIL filtration products shall in no event be liable for any special, incidental or consequential damages whatsoever, except those specifically provided for in this warranty. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations or exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights, which vary from state to state.
