What is Synthetic Oil?

What are synthetic lubricants?

Amsoil: The First in SynethicsEngines, transmissions, and other mechanical systems contain hundreds of moving parts. Though the metal surfaces of these parts look smooth, they are actually full of microscopic peaks and valleys. When the peak of one surface touches its mating surface, it causes wear. Wear may lead to costly component damage or failure. Wear reduction and failure prevention are the primary functions of lubrication.

Refined Oils

Conventional oils—the oils most people are familiar with—are refined from crude oil. Refining is a process of physically separating light oil components for heavy ones.

Crude oil contains a full range of differnt kinds of molecules. Many are similar in weight, but not in structure. The refining process cannot distinguish such molecules, so a wide assortment of molecules is present in a finished lubricant made from crude oil stocks.

Many crude oil molecules are not beneficial to the lubrication process. For example, paraffin causes refined lubricants to thicken and flow poorly in cold temperatures. Molecules containing sulfur, nitrogen, and other elements invite the formation of sludge and other products of lubricant breakdown, especially in high temperature applications. Sludge and breakdown by-products significantly increase wear rates.

The assorted molecules of refined lubricants also have differnt shapes, making lubricant surfaces irregular at the molecular level. As lubricant layers flow across one another during the lubrication process, these irregularities create friction, which consumes power, reduces fuel efficiency and increases wear and tear.

Synthetic Lubricants

Synthetic lubricants are chemically engineered from pure chemicals rather than refined from crude oil. That gives them significant advantages over refined oils.

Pure Amsoil Storage Tanks

The base stocks from which synthetic lubricants are made contain no sulfur, nitrogen or other elements that invite the formation of sludge and other products of lubricant breakdown. Synthetic lubricants can be used in higher temperatures thean refined lubricants without breaking down. Their resistance to breakdown also allows them to be used longer than refined lubricants can be used. Lubricated systems stay cleaner and last longer with synthetics.


The base stocks from which synthetic lubricants are made feature uniform and smooth molecular structures, which ensures low friction as lubricant layers slide across one another. Reduced friction increases energy through, but for greater fuel efficiency and power and reduces heat and wear for longer equipment life.

Molecular uniformity also helps synthetics resist thinning in heat and thickening in cold, which helps them protect better than refined oils over a system's operating temperature range and helps ensure secure sealing.

Designable Amsoil Lab

Many different kinds of base stocks may be used to create synthetic lubricants, allowing a synthetic to be designed for virtually any application. Some base stocks are ideal for use in extremely cold environments, others are perfect for use in extreme heat. Some are extremely safe in applications in which refined oils simply do not offer the design flexibility synthetics offer.

The designability of synthetics also allows them to be tailored very specifically to the needs of everyday applications, such as automotive engines, commercial equipment, or industrial machinery. That specificity helps ensure long life and peak power, performance, and fuel economy from the lubricated system, as well as extended lubricant life.

The Benefits of Amsoil Synthetic    Motor Oils

Improved Performance

More Power

The smooth molecular structures of Amsoil synthetic motor oils create less intrafluid friction than the relatively rough molecular structures of conventional motor oils, while their film strengths reduce metal-to-metal friction. Engines running Amsoil synthetic motor oil waste less energy overcoming intrafluid and metal-to-metal friction, allowing them to deliver more power to the transmission. Vehicles repond quicker and achieve faster top speeds.

Increased Fuel Economy

The low intrafluid friction and metal-to-metal friction reducing properties of Amsoil synthetic motor oils also improve fuel economy by delivering more of the energy created through combustion of the air-fuel mixture to the transmission.

Unlike conventional oils, Amsoil synthetic motor oils contain no light molecules that may be lost to volatillization. Volatilization thickens conventional oils and makes them more difficult to pump, while the low volatilization of Amsoil synthetic motor oils helps them maintain their original viscosity and fuel economy benefits.

Cold Temperature Starting

Amsoil synthetic motor oils retain better cold temperature cranking and pumping characteristics than petroleum oils. Beacause Amsoil synthetic motor oils resist viscosity increases in cold temperatures, they allow the crankshaft to turn fast enough to start the engine in cold winter temperatures. Resistance to cold temperature viscosity increases also allows Amsoil synthetic motr oils to maintain their pumpability for feas post startup engine lubrication and excellent wear protection.

Increased Vehicle Life

Wear Control

Viscosity Retention- The superior chemisty of Amsoil synthetic motor oils helps maintain thick protective oil films in high temperature operating conditions. Many competing motor oils contain low quality additives prone to rupture during periods of mehanical stress, affecting the oils ability to maintain a thick protective oil film during high temperature operating conditions and exposing critical engine parts to increased levels of wear.

Film Strength- Amsoil synthetic motor oils feature molecules of uniform size and shape and uniformly strong intermolecular bonds, helping them maintain an unbroken lubricating film even when faced with stressful engine operations such as rapid acceleration and deceleration.

Corrosion Protection- Acids form as combustion by products such as water, combine with oxidation by products or fuel and air constituents such as sulfur or nitrogen. Acids corrode metals, while heat helps acids damage metal eninge parts very rapidly. Amsoil synthetic motor oils contain highly effective acid neutralizing additives, something especially beneficial for diesal engines.

Water is a normal combustion by product that condenses on engine surfaces one they cool. Allowed to remain on these engine surfaces, it promotes corrosion. Stored engines are particularly prone to corrosion damage. Amsoil synthetic motor oils forms a water occlusive barrier on metal surfaces, protecting them from corrosion.

Foam Suppression- Engine operation can whip air into motor oil and impair its ability to provide adequate war protection. Anti-foam additives in Amsoil synthetic motor oils enhance wear protection by collapsing entrained air bubbles.

Contaminant Supension- Dirt, engine wear metals and combustion by products such as soot work to accelerate engine wear. Motor oil reduces the damage caused by these contaminants by carring them to the oil filter, where they become trapped. Amsoil synthetic motor oils are formulated with highly effective dispersant additives that keep contaminants suspended in the oil stream until they reach the oil filter.

Disel engines are particularly subject to soot contamination. Amsoil synthetic motor oils reduce damage caused by soot by keeping soot particles from agglomeration. As soon agglomerates and particles grow in size, wear can occur. Furthermore, viscosity increases which may lead to filter plugging.

Heat Stress Control

Heat Transfer- Excessive engine heat promotes excessive engine wear and can lead to part failure. The saturated molecular structure of Amsoil synthetic motor oils withstands higher temperatures than conventional oils before the oil breaks down. Amsoil synthetic motor oils possess a high degress of thermal conductivity, providing cooler running engines.

Thermal Stability- The uniformly sized and shaped molecules and uniformly strong intermolecular bonds of Amsoil synthetic motor oils remain intact during high temperature operation, protecting engines from varnish and oke and providing constant lubrication protection during extreme temperature operation.

Low Volatility- The light molecules present in conventional oils tend to colatilize in the presence of heat, thickening the oil and making it more difficult to pump, stressing the engine, increasing wear and decreasing fuel economy. Because they contain no light molecules that volatilize in the presence of heat, Amsoil synthetic motor oils maintain their superior protection qualities in high temperature operating conditions.

Oxidative Stability- Certain oxidation products, such as sludge, interfere with the engine's ability to function, while others, such as acids, contribute to enigine damage. Amsoil synthetic motor oils are highly supplemented with multiple premium grade oxidation inhibitors, effectively resisting oxidation.

Reduced Repairs- The superior protection and performance benefits of Amsoil synthetic motor oils reduce engine component failures, saving time and money spent on engine repairs.

Reduced Maintenance- The superior formulations of Amsoil synthetic motor oils allow them to last much longer than competing conventional and synthetic motor oils. While competing motor oil companies typically recommend 3,000 mile drain intervals, Amsoil synthetic motor oils are recommended for drain intervals of up to 25,000 miles or one year, whichever comes first.

Reduced Solid Waste- Because Amsoil synthetic motor oils may be used over eight times longer thatn conventional oills, Amsoil customers produce significanly less used oil waste.

Reduced Air Pollution- Because Amsoil synthetic motor oils improve fuel economy, they effectively reduce harmful exhaust emissions.

Save Money- Amsoil synthetic motor oils save customer money by extending engine life, reducing repairs and maintenance, increasing oil drain intervals and increasing fuel economy.
