AMSOIL's Frequently Asked Questions
How can I purchase AMSOIL products?
Order through the AMSOIL Online Store, or call Jim Ault, your preferred Independent AMSOIL dealer, to find out more or to have him get you all set up! (567) 686-7469. Become a Preferred Customer and purchase AMSOIL products at wholesale cost, which is approximately 25 percent less than retail price.
How long have AMSOIL lubricants been on the market?
AMSOIL products have been available since 1972, when AMSOIL 10W-40 Synthetic Motor Oil became the first synthetic motor oil to meet American Petroleum Institute (API) service requirements. Today, AMSOIL manufactures synthetic lubricants for virtually all automotive, powersports, commercial and industrial applications.
How does using AMSOIL synthetic motor oil affect new vehicle warranties?
Using AMSOIL synthetic motor oil has no affect on vehicle warranties. A federal law called the Magnuson-Moss Act (1975) prevents original equipment manufacturers from putting conditions on vehicle warranties attached to any product or service identified by brand, trade or corporate name, unless the manufacturer provides that product or service free of charge. This means consumers have the freedom to use aftermarket products of their choice without fear of losing the original limited or implied vehicle warranty. For additional information, contact the AMSOIL Technical Department at (715) 399-TECH (8324) or tech@amsoil.com.
Will extending oil change intervals void new vehicle warranties?
No. Extending oil change intervals will not void new vehicle warranties. To affect the vehicle warranty, it must be determined that the lubricant was directly responsible for the failure; if the oil didn’t cause the problem, the warranty cannot be voided, regardless of brand or length of time in use.
Does AMSOIL have a warranty for products?
Yes. AMSOIL provides a limited warranty on all AMSOIL lubricants and filters.
What is the difference between synthetic and conventional oil?
Motor oil, whether synthetic or petroleum-based, consists of molecular chains of hydrogen and carbon atoms, referred to as hydrocarbons. Petroleum crude oil is a thick, highly flammable dark-brown or greenish liquid with high energy density. Many contaminating elements exist in this complex mixture of hydrocarbons, including sulfur, nitrogen, oxygen and metal components such as nickel or vanadium. Petroleum crude oil is the raw material used for a wide variety of petrochemicals, including solvents, fertilizers, plastics and lubricants.
The oil refining process separates the various types of molecules in the oil by weight, resulting in a concentrated batch suitable for manufacturing products such as gasoline, LPG, kerosene or lubricant base oils. The chemical composition of conventional motor oil can vary substantially depending on the raw crude oil refining process.
While petroleum base oils are refined, synthetic base oils are manufactured and can achieve a higher performance level. Synthetic oil is chemically engineered for a certain molecular composition with a tailored and uniform structure. Such fine-tuned control over the final molecular composition of synthetic oils is the key to their superior performance properties. Designing molecular structures in a planned and orderly fashion results in molecules, and end-products, that are far more stable than their refined petroleum counterparts.
Why are AMSOIL synthetic motor oils capable of extended drain intervals?
AMSOIL synthetic motor oils are formulated using premium synthetic base oils, and the highest-quality additives, that provide extended-drain capabilities. AMSOIL synthetic motor oils achieve greater cleaning powers, while providing better equipment protection over longer oil drain intervals. The unique synthetic formulation and robust TBN retention of AMSOIL synthetic motor oils work to resist oxidation and neutralize the acids that shorten the service lives of other oils. Their characteristic resistance to high-temperature volatility (burn-off) helps reduce oil consumption, while maintaining viscosity over longer periods of time than other oils. Check the product data sheet for specific recommendations.
How do AMSOIL synthetic motor oils compare to other motor oils?
The importance of using good-quality oil in an engine cannot be overstated. AMSOIL synthetic motor oils consistently outperform conventional and other synthetic oils in virtually every category of performance, including wear protection, extreme high- and low-temperature performance, foam control, viscosity retention, rust and corrosion protection, volatility and fuel economy. While other brands may provide good performance in some of these areas, AMSOIL synthetic motor oils consistently perform at the top in every category. Drivers can have confidence knowing that AMSOIL synthetic motor oils provide maximum performance and protection.
Can synthetic oil be used in new engines?
Yes. Synthetic oil is perfectly safe for use in both new and high-mileage engines.
