Warranty Laws: Learn The Federal Law & Become and Informed Consumer

Could using AMSOIL motor oil void your new vehicle warranty?

Absolutely not. Vehicle manufacturers recommend using motor oils meeting certain grades and American Petroleum Institute service requirements. Whether the motor oil is petroleum based or synthetic will not affect warranty coverage. The manufacturer is required to cover all equipment failures it would normally cover as long as the oil meets the requirements and was not the cause of the failure. AMSOIL exceeds these requirements and has never been deemed the cause of an engines failure. Even so, AMSOIL has its own limited warranty, protecting you even further. In addition, the Federally mandated Magnuson-Moss act states that a manufacturer may not require the use of a specific brand of aftermarket product unless it is provided free of charge.

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.

Could your new vehicle warranty be voided if you don't change your oil according to the manufacturers recommended change intervals, such as when using AMSOIL?

Absolutely not. AMSOIL synthetic motor oils are guaranteed to run 25,000 miles to 35,000 miles (Signature Series Severe Service 0W-30 oil) or one year in mechanically sound engines, providing, of course the oil is kept free of contaminants by changing the oil filter according to the manufacturer's recommendation or when using an AMSOIL Absolute Efficiency oil filter changing the filter at 25,000 miles/1-year (for gasoline or diesel engines), whichever comes first. If using the AMSOIL Dual-Remote or Dual-Gard By-Pass Filtration unit then the oil and By-Pass filter is changed as indicated by oil analysis testing. AMSOIL coinded the phrase "extended drain interval" and it has been validated by over 35 years of industry testing and tens of thousands of motorists and millions of over-the-road miles.

AMSOIL synthetic motor oils provide extended drain performance because they don't break down in heat like conventional motor oils do. AMSOIL motor oils don't form performance-robbing deposits, and don't volatize (burn off), which alters viscosity and increases oil consumption. Finally, AMSOIL's superior additive package, a key element in the oil's ability to function, holds up under engine stresses, remaining serviceable for the full 25,000 to 35,000 miles, or indefinitely when AMSOIL By-Pass Filtration and oil analysis is used.

Additionally, if there is ever a question of whether or not a particular oil was the cause of an engine failure make sure to get a sample of the used oil in a clean bottle, typically 6 oz. minimum. The oil can then be sent to two independent testing labs for analysis (* labs are located throughout the country). Remember, an informed consumer is your best defense against being taken advantage of by a vehicle dealership or service center.

If you need the address, location, phone number and contact information for an oil testing laboratory(s) please contact me.

Only if an oil is determined to be the direct cause of an engine problem can a manufacturer or dealership deny warranty coverage for that specific problem. In this situation the AMSOIL warranty would apply, and the AMSOIL Technical Services Department would assist you in processing your claim and getting your vehicle repaired. That's AMSOIL's pledge to you. AMSOIL Inc. sells millions of gallons of oil per year and warranty claims are a rare occurrence. If you ever have a warranty problem with an automobile manufacturer (or snowmobile, boat, RV, motorcycle, etc...) or dealership, AMSOIL will assist you by analyzing the problem and providing data supporting the fact that repairs should be made under the vehicle manufacturer's warranty. If this does not resolve the problem. AMSOIL will submit a claim with their insurance company and request that an adjuster have the vehicle repaired and pursue legal settlement later if necessary. The fact is there never has been an engine failure attributed to the non-performance of AMSOIL products, and we do not expect there ever will be. If it ever did, both AMSOIL and their insurance company would make certain your problem was resolved.

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
