If a car dealership, service center or other business states that using AMSOIL will void your new vehicle warranty, ask for that statement in writing and send it to AMSOIL Technical Services (AMSOIl Inc., AMSOIL Bldg, Superior, WI 54880). 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 what the specific statement was. AMSOIL will then send a letter to the business informing them that their position is inaccurate, and, in fact violates existing law. Your name will be held in confidence. A sample of this letter is included below.
Special Letter From AMSOIL To Your Car, Truck, Motorcycle, Boat, Snowmobile, Small Engine, etc.. Dealership:
Dear, Mr. Service Manager (actual name you supply will be put here),
It has come to our attention that you (or employee's name) have been informing our mutual customers that the use of AMSOIL Synthetic Motor Oils voids your manufacturers' warranty. This claim is not true. Please review the following facts about warranties and AMSOIL Synthetic Motor Oils.
Original Equipment Manufacturers (OEMs) recommend consumers use lubricants of the proper viscosity grade and service classification. Any oil, whether it's petroleum oil or synthetic, may be used without affecting overall warranty coverage. OEMs pay or deny warranty claims based on findings of failure analysis. To affect the vehicle warranty, the lubricant must be directly responsible for the failure. If the oil did not cause the problem the warranty cannot be voided, regardless of the brand of oil used, or the length of time or number of miles the oil was used. To flatly inform customers that the use of AMSOIL Synthetic Motor Oil voids their warranty is not true, is not supported by any OEM and damages AMSOIL INC.
Synthetic motor oil was introduced to the automotive public in 1972 by AMSOIL INC., with its introduction of the world's first API (American Petroleum Institute) rated synthetic motor oil. Since then, every major engine oil manufacturer has followed AMSOIL's lead and has introduced synthetic oils of their own. AMSOIL Synthetic Motor Oils exceed the most demanding worldwide performance standards. They are specially formulated for long service and provide superior performance and protection to that provided by conventional oils, and can be installed and used with complete confidence. AMSOIL INC. offers our customers warranty coverage and provides the proper insurance to cover an oil related failure, should one ever occur.
We appreciate your attention to this matter and anticipate there will be no further intimidation of our customers by your insuring no one implies or states that the use of AMSOIL products will "void" their warranty coverage. Thank You.
AMSOIL INC., Customer Service Division
