Best Synthetic Motor Oil Brand

To be considered the best synthetic motor oil brand in a very crowded market can be a tough claim to back up. There are many factors that go into the making of a quality motor oil. To be called the best means the oil not only has the correct ingredients and the proper formulation, but also can provide real test data to illustrate its superiority. In this blog post, we will present information that will establish facts to lay claim that AMSOIL is the best synthetic motor oil brand.

Why Is AMSOIL the Best Synthetic Motor Oil Brand?

AMSOIL was ahead of their time. In 1972, AMSOIL 10W40 Synthetic Motor Oil became the very first synthetic motor oil in the world to meet API or American Petroleum Service requirements. After years of intensive research that was inspired by aerospace technology, this engine oil outperformed regular mineral based oils in all areas. By becoming the first engine oil to meet API service requirements, it signaled a new age in the science of lubrication.

Today, almost every engine oil manufacturer understands the superiority of synthetic lubricants. They were forced to follow AMSOIL’s lead by introducing their own synthetic engine oils. The fact is, AMSOIL is the First in Synthetics! Immediately, by being the first synthetic oil manufacturer, they have an advantage in both experience and in depth knowledge of lubrication chemistry.

Before we go any further, let us establish why synthetics are superior to conventional or mineral based lubricants. You may know that synthetic lubricants can outperform mineral based oils, but you might not understand why this is the case.

Mineral based oils come from the ground and are refined from crude oil. Crude oil unfortunately contains many unwanted and useless byproducts that contribute nothing to their performance. They contain such contaminating elements as oxygen, nitrogen, sulfur, nickel, and vanadium. Oil refiners have tried to remove these byproducts, but it has been so far not possible to completely remove them through the refining process.

Also, there are differences at the molecular level. Mineral base stock oils naturally have an irregular molecular structure and contain unwanted impurities.

These uneven sized molecules found in conventional motor oils create fluid friction. Also, the impurities or byproducts found in mineral oils can cause unwanted contaminants and deposits that can affect engine performance.

AMSOIL synthetic base stock oils are chemically engineered so that they are considered pure base oils that are devoid of any unwanted contaminants or byproducts. Synthetic base stock oils are man made and have even, perfectly sized molecules, plus they don’t have any impurities.

These pure and versatile base oils, along with their uniform molecular structure, contain properties that deliver superior friction reduction, tougher film strength, outstanding extreme temperature capabilities, and enhanced fuel economy. The fact is, mineral based or conventional lubricants cannot provide these types of high performance benefits.

AMSOIL has over 50 years of synthetic oil manufacturing experience. This experience gives them a huge advantage over other synthetic lubricant manufacturers. They know which combination of synthetic base oils to use and with this vast experience, their oils deliver superior performance.

AMSOIL Provides Superior Engine Protection

There is only a microscopic film of oil that keeps metal surfaces in your motor from coming into contact and causing unwanted wear. AMSOIL chemists have created a unique line of high performance synthetic engine oils that are capable of creating a tougher microscopic fluid film than regular or mineral based oils. AMSOIL synthetic base oils were chosen for their tougher and stronger base oil characteristics and properties. They help to reduce friction, wear, and provide longer engine life.

To illustrate AMSOIL’s advanced technology, they decided to put their motor oil through an industry standard oil test. The test’s industry designation is ASTM D-7320, called the Sequence III G Engine Test. This test was created to evaluate automotive engine oils for engine wear, piston deposits, oil thickening, and oil consumption during a moderately high temperature, high speed environment.

For an engine oil to meet API SN and ILSAC GF-5 engine oil specifications, it must pass this test. The results that an engine oil gets in this 100 hour test are an important indicator of how the engine oil will perform during real world service.

The motor oil AMSOIL chose for this test is called the Signature Series Motor Oil. Historically, Signature Series has passed this test with flying colors. Still, AMSOIL was not satisfied with passing the test. They wanted to see how far they could push their Signature Series Motor Oil to the limit, so they decided that instead of running it the standard 100 hours, they wanted to test the oil for 200 hours, or double the industry standard length for the Sequence III G Engine Test. See the results of this test here!

Not surprisingly, Signature Series 5W30 Synthetic Motor Oil aced the test easily. The final results for this brutal and unique 200 hours test illustrate Signature Series’ high performance capabilities at delivering superior wear protection, oxidative stability, and deposit control.

Running AMSOIL’s Signature Series through the 100 hour and 200 hour tests illustrates why AMSOIL is the best synthetic motor oil brand. The benefits to motorists are many. Today’s engines require that motor oils deliver protection in extreme operating environments. With engine design advancements such as variable valve timing, direct fuel injection, turbochargers, and other high tech engineering systems that help to improve performance and fuel economy,  abnormally difficult operating environments have arisen for modern engine oils.

The environment created because of these advanced systems are much higher operating temperatures, higher pressures, contaminants, and more mechanical shear. In addition, these tough environments will most likely result in viscosity loss to the engine oil due to these increased mechanical shears. With all that a motor oil has to deal with, they must help to guard against all the abnormal conditions just stated and still maintain their lubricating properties.

It’s been a huge ask for most oil manufacturers with the exception of AMSOIL. AMSOIL was a trend setter and they are visionaries. They immediately understood why the aerospace industry needed synthetics. Synthetics provide amazing performance abilities and benefits relative to conventional or mineral based oils.

AMSOIL was prepared from the get go and now that modern engine designs require an advanced synthetic engine oil, conventional or mineral based oils have been left behind in the dust. This illustrates why AMSOIL for over 50 years was ready and willing to handle these modern day requirements that are necessary to keep engines protected.

The test results illustrate that Signature Series offers superior protection against wear, viscosity increase, and harmful deposits during the most brutal of operating conditions. Using such a motor oil will help car owners to maximize the longevity and performance of their vehicles. This synthetic motor oil’s ability to keep engine components clean while exposed to the extreme stress allows advanced engine systems to operate efficiently and demonstrate long service life. AMSOIL Signature Series’ superior performance capabilities along with its long drain capacities provides an unprecedented combination of value and quality not found with other engine oils.

AMSOIL Synthetic Oils Deliver Superior Cold Temperature Performance

When winter time arrives and temperatures plummet, conventional motor oils begin to thicken and flow slower. When an oil thickens due to cold temperature, this leads to critical engine parts remaining unprotected for a short period of time. AMSOIL synthetic lubricants are naturally capable of remaining fluid when temperatures reach extremely cold levels. Independent tests have confirmed that AMSOIL’s synthetic fluids provide 36% faster and easier cold starts when compared against regular oils. This translates to the lubricants reaching critical parts faster, thus providing internal engine components superior and quicker engine protection and reduced wear.

Engine manufacturers along with lubricant manufactures understand that the majority of engine wear occurs during cold dry startups. This unwanted wear during cold startups amounts to 80% of an engine’s wear. Extreme cold temperatures can cause vehicle breakdowns to be dangerous and the fact is, most individuals are not understanding the severe negative effect that cold temperatures can have on conventional lubricants. A lubricant’s cold temperature performance illustrates its capability to flow when an engine or other system within the vehicle is cold.

Cold temperatures are not only what feels cold to humans, but also refers to an engine’s typical operating temperature of 212 degrees F. Cold startups during warm summer days can also be considered cold to an engine. Cold startup lubrication is directly impacted by an oil’s cold flow capabilities and the impact can be felt at higher temperatures than most people could imagine.

The following is an example of how a conventional oil can have negative effects on an engine even when temperatures do not reach extremely cold levels. Early in 1991, General Motors stopped the sales of their Corvette ZR-1. At their Bowling Green, Kentucky assembly plant, 8 Corvette engines had seized. The ambient temperature had only dropped to slightly below freezing. At cold dry startup, the hard-to-pump engine oil did not flow fast enough to the front camshaft bearings of the engines and they failed due to the lack of lubrication.

General Motor engineers had decided that it was imperative that only a synthetic engine oil be utilized in the Corvette ZR-1 motor. This seemed to solve the problem. The fact is, as this example illustrates, cold temperatures, even slightly cold, can cause a conventional oil to thicken enough so that it cannot flow fast enough through the narrow oil galleys. This slower-than-normal fluid flow leaves critical engine components unprotected long enough that it causes undue friction and wear. The natural paraffins in mineral based oils will only worsen this cold temperature problem.

On the other hand, AMSOIL uses chemically engineered synthetic base oils when formulating their motor oils. These high performance base oils contain no paraffins, which allows the oil to remain fluid and flow quickly during extremely cold temperatures down to a frigid -60 degrees F. This means during any cold dry startups oil will flow quickly to bearings and other critical engine parts, keeping them well protected. AMSOIL’s proprietary synthetic formulations deliver the correct and necessary fluid flow during extreme temperatures and these synthetic base oils provide metal surfaces with high film strength in both cold and extreme heat, giving AMSOIL engine oils superior all-weather performance and protection.

No matter the temperature, AMSOIL is the best synthetic motor oil brand.

Car manufacturers are being forced to re-engineer their engines to meet tough fuel economy requirements. To accomplish this, engines are being forced to run hotter than ever. The average operating temperature for car engines is up to 230 degrees F and temperatures rise even further when put under heavy loads. Modern engine designs are putting severe stresses on conventional engine oils, causing them to oxidize and create unwanted sludge and deposits.

Tests conducted on AMSOIL synthetic lubricants has shown that engines stay 81% cleaner or 5 times better than regular mineral based oils. AMSOIL synthetic engine oils are far superior at resisting the formation of deposits.

Automakers are designing their engines with direct fuel injection and turbochargers so that they can meet the government’s tough fuel economy and emission standards. These performance enhancing technologies, though helpful in meeting strict government standards, they unfortunately create extreme heat within the engine, which can lead to a series of issues, all of which can cause a loss in engine performance and service life.

Let’s discuss some of the unfortunate issues that can arise and how AMSOIL has engineered engine oils that effectively eliminate these issues and illustrate again why they are the best synthetic motor oil brand.

The Cause of Deposits and Sludge

Heat is the enemy of an engine oil and can cause it to slowly break down. When engine oil is exposed to excessive heat, especially conventional oils, deposits start to form on the intake valves. These deposits hinder air flow into the motor and these deposits create poor sealing of the combustion chamber. When the intake valve does not seal effectively or correctly, this can cause the engine to idle rough and misfire, which leads to a reduction in power and fuel efficiency.

When heat becomes extreme, this can lead to an engine oil additive’s chemistry to deplete. When heat causes an oil’s chemistry to change in a negative way, this prevents the oil from lubricating, protecting, and cooling vital engine components. As heat continues to break down the conventional oil, sludge begins to form due to the naturally present byproducts in the oil. Sludge formation tends to clog the narrow oil galley passageways, which leads to a restriction in oil flow towards critical engine components. This lack of oil flow can cause undue friction and wear.

For those engines that are designed with variable valve timing (VVT), it is important to eliminate and prevent any sludge formation. The intricate parts found in variable valve timing systems are extremely sensitive to sludge. If sludge were present, it would cause the system to fail and to operate improperly, thus resulting in reduced engine performance.

To illustrate AMSOIL’s superior capabilities when exposed to extreme heat conditions, their Signature Series 5W30 Synthetic Motor Oil was put through the ASTM D-6335 Test. During this independent third party test, Signature Series 5W30 performed admirably. When compared to a leading conventional engine oil, Signature Series delivered 81% fewer deposits, or 5 times less deposits than conventional oil. In other words, it stayed 5 times cleaner than a regular mineral based oil.

How to Reduce Oil Consumption

When oil is exposed to extreme heat, it can volatize. When oil volatizes, the lighter molecules can evaporate and what is left behind are the heavier components. When this happens, the oil’s viscosity increases, thus making it more difficult for the oil to flow and circulate and also contributes to poor fuel efficiency. Most likely you’ve experienced oil volatizing when you notice that your vehicle seems to be using or consuming oil more than normal, thus forcing you to top off the oil frequently.

Oil volatization is also detrimental to the environment due to the creation of unhealthy emissions that add to air pollution. If too much motor oil is burned off or volatized and left unchecked, then at some point the engine will be starving of the necessary oil that is needed to lubricate and protect critical engine components. The result could lead to catastrophic failure to the engine.

Again, AMSOIL conducted a third party independent test called the ASTM D-5800 NOACK Volatility Test. AMSOIL’s Signature Series Synthetic Motor Oil resulted in 38% less oil consumption than regular motor oils. This translates to less oil consumption and fewer oil top offs. As illustrated earlier in the Double Length Sequence III G Engine Test study, AMSOIL’s Signature Series Synthetic Motor Oil showed 86% superior performance in terms of fewer piston deposits as compared to industry standards for 100 hours. Also, this oil provided additional proof of its superior performance by easily passing the 200 hour mark for the same test.

The bottom line is, AMSOIL Signature Series Synthetic Motor Oil, with its unique combination of pure synthetic base oils and its high performance additives, delivers outstanding heat resistance and will deliver the kind of performance needed to keep your engine clean of deposits and running at peak efficiency.

How to Improve Fuel Economy

The ability to improve fuel economy for the average car owner would be a welcomed benefit. This next area of discussion will also illustrate another reason why AMSOIL can be considered the best synthetic motor oil brand. Remember when we discussed the differences in molecular structure between conventional mineral based oils versus synthetics? The base stock oils found in mineral oils contain molecules of different sizes and weights. Also, these conventional base stock oils naturally come with unwanted byproducts such as wax.

These base oils, with all their warts, definitely require the expenditure of more power and energy to get them to flow throughout the engine. This added expenditure of power contributes to a reduction in fuel efficiency and economy. The opposite is the case when discussing AMSOIL synthetic engine oils. The base oils used in the manufacturing of AMSOIL motor oils contain molecules of uniform structure and weights. These same sized molecules flow and slip easily and without restriction over each other.

Due to their purity and lack of unnecessary byproducts, they flow easy with minimal energy requirements. Because less energy is needed to circulate synthetic base oils, friction is reduced and fuel economy is improved.

From the get go, synthetic base oils will reduce friction and improve fuel economy. These two performance enhancements and abilities are provided before the discussion arises concerning the additive chemistry. To further improve engine efficiency and fuel economy, AMSOIL utilizes other helpful additives to enhance performance.

Added to the friction reducing synthetic base oils are unique friction modifiers. These friction modifiers react chemically inside an engine when exposed to heat, leaving behind a film on the metal surfaces that radically reduces any friction that may exist between the metal surfaces. Along with these friction modifiers are added anti-wear inhibitors. These anti-wear inhibitors work synergistically with AMSOIL’s friction modifiers. Together, these two additives work in harmony to eliminate premature wear and reduce friction. They both help to enhance fuel economy by reducing friction and drag.

Also, AMSOIL chemists add oiliness additives to the unique formulation. These oiliness additives work in a unique fashion where they enable to oil to literally penetrate the subsurface of the metal surfaces they come in contact with and when the engine is in operation, they literally sweat out of the subsurface and help to provide an extra lubrication source. All these additives, along with the naturally friction reducing base oils, help to give AMSOIL synthetic motor oil’s superior abilities at improving fuel efficiency and economy versus conventional mineral oils.

Remarkable Environmental Benefits

AMSOIL not only was the “First in Synthetics”, but they also blazed the trail in terms of environmental conservation. When all original equipment manufacturers were specifying 3,000 mile drain intervals, AMSOIL was revolutionary when they invented the 25,000 mile guaranteed drain interval. At first, they were laughed at by the industry because of this 25,000 mile drain interval. Well, AMSOIL had the last laugh and now the world realizes that 3,000 mile drain intervals are incredibly wasteful, not only for the wallet but more importantly the environment.

AMSOIL synthetic motor oils were highly engineered to offer safe extended drain intervals. Their oils are designed to be resistant to chemical degradation, to protect against oil consumption, and are able to neutralize contaminants far better than regular oils. Because of all these capabilities and reasons, they can offer much longer service life.

For example, AMSOIL Signature Series Synthetic Motor Oil can and will dramatically reduce oil waste. This amazing engine oil can safely extend you oil drain intervals to 25,000 miles, 700 hours of operation, or 1 year, whichever comes first under normal operating conditions. Imagine if every single automobile and light truck in the United States followed this extended drain interval of 25,000 miles. Up to 35.7 billion quarts of engine oil would be eliminated from the supply chain system. That would truly be a monumental environmental benefit.

AMSOIL Synthetic Lubricants also offer reduced emissions. These reduced emissions can have a direct impact on the air we breathe. Tests and real world experience has illustrated that conventional mineral based engine oils are more susceptible to oil volatility than synthetic oils. This propensity to the evaporation of oil when exposed to extreme heat means the mineral oil will evaporate more easily and burn more readily, thus producing unwanted emissions that exhaust the car’s tailpipe and thus enter the air we breathe. This contributes to dangerous air pollution.

AMSOIL was engineered to resist oil volatility and to help reduce air emissions and air pollution. Another way that AMSOIL synthetic oils benefit the environment is through their abilities to improve fuel efficiency and fuel economy. Unlike regular mineral based engine oils, AMSOIL synthetic engine oils are designed with even and uniform molecular structures. Their uniform molecular structure gives the base oil the ability to flow without friction. The molecules flow easily over each other, thus reaching critical engine parts without consuming too much engine power.

By delivering less restriction and friction, thus reducing the amount of energy needed to circulate the oil throughout the engine, fuel economy is improved which leads to less fuel consumption and a direct benefit for the environment. Also, beyond the performance capabilities of AMSOIL that directly impact the environment in a positive manner, the AMSOIL company itself goes a step farther.

For example, AMSOIL utilizes plastic containers that are manufactured from post-consumer resins. Also, AMSOIL products are packaged using recycled cardboard, which provides significant environmental savings. From an environmental standpoint, AMSOIL is the best synthetic motor oil brand.
