What Is Synthetic Motor Oil?

Although there are several different manufacturing processes used for synthesizing synthetic motor oils, all of them begin by using raw ingredients extracted from underground resources. While conventional oils are then transported and then refined, synthetic oils are distilled and “cracked” into their component molecules. This process allows impurities to be removed from the crude oil, and today’s advanced cutting-edge chemical technologies allow engineers to re-engineer the basic molecules into precision formulas perfectly tailored to modern vehicle engines. Most major manufacturers of synthetic motor oils then carefully work to blend special additives to create the perfect oil to meet the demand of today’s high-powered engines.

Top-quality synthetic motor oils are better able to resist more demanding atmospheric conditions, and provide much better protection in cold-weather starts than conventional motor oils. By absorbing heavy metal contaminants and sludge particles, synthetic motor oils prevent and dissolve toxic build-ups in critical engine components.

During and immediately after the global conflict known as World War 2, the exigent needs of the combatant pushed humanity’s scientists to new heights. Breakthroughs in chemical science led to the creation of synthetic, and partially synthetic, oils. Offering a wide bevy of advantages over traditional refined petroleum or natural mineral oils, including greater resistance to extreme temperatures, enhanced protection against ash deposit formations in engine hotspots, and dramatic improvements in horsepower and greater torque on the engine.

By removing heat, heavy metal components and other contaminants from critical engine parts, today’s advanced synthetic motor oils protect high-performance vehicle engines from toxic build-ups of sludge and other corrosive elements. By using custom molecular formulas with enhanced high-lubrication esters, synthetic motor oils work to reduce exhaust filter blocking and can dramatically reduce wear and tear on high-performance automobile engines.

What Are The Advantages Of Using Synthetic Motor Oil?

Certainly not every vehicle owner is a certified mechanic and automotive repair expert, but many drivers feel comfortable regularly changing and maintaining the motor oil in their personal vehicle. Commercial garages and oil change businesses often charge expensive fees to drain and replace motor oil in vehicles, and savvy vehicle owners know that they can save money by doing the work themselves at home. As geopolitical events around the globe affect petroleum prices, many vehicle owners know that it is a good idea to have plenty of synthetic motor oil on hand at home to insulate against dramatic price swings or instabilities in planetary demand.

Synthetic motor oil can also be used for a wide variety of other lubrication needs, and is designed to withstand extreme temperature fluctuations with ease.

What Are The Different Types of Synthetic Motor Oil?

Every major manufacturer of synthetic motor oils use carefully guarded corporate trade secret processes to distill, refine and carefully blend their proprietary formulas. That being said, all synthetic motor oils consist of synthesized petroleum products, including chemically-modified petroleum components, instead of whole crude oil. Generally speaking, synthetic motor oil is composed of far more esters, by weight, than traditional motor oils, dramatically increasing the lubricating power of the oil.

Just as with traditional motor oils, synthetic motor oils are rated by viscosity, an industry metric that describes the oil’s change of viscosity with variations in temperature. The Society of Automotive Engineers has established the most commonly-used scale for grading motor oils according to viscosity, using traditional gradings (from low to high viscosity) of: 0, 5, 10, 15, 20, 30, 40 and 50. The first four viscosity gradings (0, 5, 10, 15 and 25) are usually suffixed with the letter W to indicate that they are designed to be used in winter and cold climate atmospheric conditions.

Synthetic oils graded at viscosity 20 are divided into blends designed for summer or warm weather use and W20 grade oils that are better suited to cold-start conditions.


Considerations for Choosing the Best Synthetic Motor Oil

Much like other motor oils, there are lots of choices available. The good thing about this is that you’re sure to find an oil that works for your car. The bad part is that you have to weed through hundreds of options and hope you make the right choice. Before you throw money away on motor oil that doesn’t fit your needs, make sure that you check out these considerations before you purchase

Viscosity

The far most important metric used for choosing the right synthetic motor oil is the viscosity. Lower viscosities are better adapted to cold weather use, while higher viscosities can help improve engine performance in warmer ambient conditions.

Fuel Economy

The less friction that synthetic motor oils put on the internal pathways of the motor, the greater the performance in fuel economy as the engine has to work less hard to circulate the oil. A good blend of quality synthetic motor oil will lead to significant improvements in fuel economy in today’s advanced automotive engines.

Lubrication & Frictional Properties

The most important role of any synthetic motor oil is to lubricate and reduce friction of the moving parts of an automotive engine. Today’s advanced formulas are designed to dramatically reduce friction and provide long-lasting lubrication to critical engine components.

Special Additives

Many of today’s major manufacturers of synthetic motor oils carefully blend proprietary additives to help prevent oil leaks, deposits and sludge build-up in the engine.

Conclusion

Every vehicle owner knows the important role that a high-quality synthetic motor oil can play in improving the performance and increasing the longevity of today’s advanced engines. By carefully synthesizing custom-engineered petroleum molecules and blending them with advanced additives, today’s fully synthetic motor oils can provide outstanding protection against corrosive build-ups of sludge and other toxic deposits inside critical engine parts. Today’s major manufacturers of synthetic oils use scientific breakthroughs to create custom formulas capable of providing unparalleled lubrication protection under even the most extreme engine operating conditions.

While many motor oils are suitable for higher-mileage vehicles or older-model engines, only Pennzoil Ultra Euro L has been specially synthesized and blended to protect critical engine parts in today’s advanced European motors. Designed to remove and absorb damaging contaminants before they can form toxic build-ups in high-performance European motors, this synthetic will perform flawlessly under even the most extreme speed, load and heat conditions.
