What is The Best Synthetic Motor Oil?
Are you looking for the best synthetic motor oil for your engine? Numerous companies claim to have the best, but AMSOIL provide’s proof.
AMSOIL was founded on the principle of innovation. Al Amatuzio, the company’s founder, began commercially selling synthetic oil in 1968. Four years later, AMSOIL Synthetic Motor Oil became the world’s first synthetic oil to meet API specifications.
By ignoring commonly accepted limitations, we establish a new standard of performance.
The best synthetic oils provide greater mileage, keep the engine cleaner, perform well in both low and high temperatures, and protect the engine by preventing wear.
AMSOIL’s Signature Series: Is This the Best Synthetic Motor Oil?
Not only is AMSOIL’s Signature Series the best synthetic oil they’ve ever made, it’s also superior to any competitive oil they’ve tested. Over-engineered? Perfect.
AMSOIL’s motor oils are engineered for people who want the best protection and performance. Precision-made with cutting-edge technology and a long history of making the best motor oil in the world. In the end, the engine protection is so good that it blows the doors off the highest industry standards.
Maintain your vehicle for a longer period of time with less time spent on maintenance. Consider using a synthetic motor oil. They contain anti-stick additives, are resistant to thermal breakdown, and reduce engine wear.
Protects Against Engine Wear
Our synthetic motor oils can be used in engines that require those specifications.
AMSOIL’s Signature Series Protects Against LSPI
AMSOIL equipped the Signature Series Motor Oil with an advanced detergent system that guards against harmful deposits and pre-ignition at low speeds (LSPI).
What is LSPI (low-speed pre-ignition)?
LSPI has been known to crack pistons and rods.
LSPI refers to the spontaneous ignition of a fuel/air mixture prior to spark ignition.
It is a component of pre-ignition. Pre-ignition (engine knock) has been a feature of internal combustion engines since their inception.
LSPI, on the other hand, occurs at low speeds and high torque, such as when taking off from a stoplight in T-GDI engines.
This scenario can result in conditions where the fuel/air mixture ignites prematurely in the combustion cycle, causing the engine’s timing to be thrown off.
While the expanding combustion charge is moving up the cylinder, it collides with the piston, potentially destroying the pistons or connecting rods
Using the best Synthetic Oil can help prevent LSPI
Experts believe the cause is partly due to oil/fuel droplets or deposits in the cylinder spontaneously igniting. Before spark-triggered ignition, the droplets and deposits contain enough heat to ignite the air/fuel mixture.
Oil formulation can play a role in reducing LSPI.
Certain motor oil ingredients may contribute to the development of LSPI, while others may aid in its reduction. It’s tempting to think, “Well, just add a bunch of ingredients that help reduce LSPI to your formulations.” However, certain ingredients that aid in LSPI reduction have been restricted in motor oil formulations for other reasons over the years.
Oil formulators are faced with a scientific balancing act that is difficult to master. Making motor oils that provide excellent wear protection, resist the increased heat generated by turbocharged engines, prevent deposits, act as a hydraulic fluid, and, most recently, combat LSPI is no easy task. But it is possible.
It is the overall performance of the formulation – not just the performance of one or two ingredients – that is important.
For the time being, take it easy.
You don’t need to be concerned about LSPI for the time being.
To prevent LSPI, your vehicle’s computer has been programmed. However, running your engine under those circumstances can result in improved fuel economy.
AMSOIL Synthetic Motor Oils meet the latest specs
AMSOIL synthetic motor oils meet or exceed the latest industry standards, including ILSAC GF-6, API SP and GM dexos1 Gen 2.
AMSOIL’s synthetic motor oils can be used in engines that require those specifications.
With regard to LSPI, AMSOIL achieved 100% protection against GM’s Gen 2 specification in the required engine test.
using AMSOIL helps Protect Turbos
Using AMSOIL in your vehicle can help in the resistants to oxidation and neutralizes acids because of its stable formulation. In high-temperature engine environments, deposits are common, and AMSOIL’s Signature Series Motor Oil is uniquely capable of protecting against them.
Due to the fact that turbochargers are now installed in more vehicles than ever before, this is an especially critical issue.
Turbos can get very hot and stressful, which can cause some oils to break down and make bad deposits on the bearings. This process is called “turbo coking.” Over time, turbos can lose power or break down completely. In fact, AMSOIL Signature Series Synthetic Motor Oil is so good at coping with heat that it can protect turbochargers 72% better than the GM dexos1 Gen 2 specification says it should. 4 It lets modern engines reach their full power and service life.
AMSOIl’s Signature Series Motor Oils protects turbochargers from extreme heat and deposits that can damage them. It also has a high film strength to protect against accelerated wear.
AMSOIL gives better Sludge protection
Maximum Power to Clean Sludge.
AMSOIL Synthetic Oil has 50 percent more detergents3 to keep oil passageways clean and to help the oil flow through the engine more smoothly and efficiently. Their Signature Series has detergent and dispersant additives that work so well that it protects against sludge5 90% better than a standard in the industry.
To achieve maximum life expectancy, use an oil with high concentrations of anti-oxidant, dispersant and detergent additives.
Severe service makes the engine sludge.
The way the equipment is used also affects how likely it is to have problems with sludge or varnish.
Stop-and-go driving, frequent/long-term idling, and operating in very hot or very cold weather can all lead to sludge and varnish, especially if you use more volatile conventional oils. If sludge has already built up in your engine, you can use an engine flush to remove it.
It turns out that most automakers say in their owner’s manual that operating under any of the above conditions is considered “severe service,” which means that the oil needs to be changed more often.
Mechanically, factors such as excessive oil in the oil sump, antifreeze contamination, excessive soot loading, excessive oil foaming, inefficient engine combustion, excessive blow-by, and emission-control system malfunction can all contribute to the formation of sludge and varnish.
By maintaining your vehicle properly and using properly formulated, premium synthetic lubricants, such as AMSOIL synthetic motor oil, you can avoid the “black death.”
Using AMSOIL Top-offs are reduced
AMSOIL’s Signature Series’ uniform molecular structure prevents evaporation and concentrates the fluid where it is most needed – protecting your engine. As a result, it contributes to the reduction of oil consumption.
As a result, not only does the engine stay cleaner, but the amount of top-off oil you need to add between oil changes is reduced as well. As the graph above illustrates, it is the best synthetic oil among those that have been tested.
Signature Series falls far below the API limit for volatility, reducing the need for frequent oil top-offs and limiting vehicle emissions.

The Best Synthetic Oil Must Keep It Together
AMSOIL’s Signature Series Motor Oils have better thermal durability than both conventional and synthetic motor oils. This means it doesn’t break down as quickly.
This means that the oil keeps its viscosity better, which means that it protects the engine better and lasts longer.
In normal use, you can go up to 25,000 miles or a year without changing your oil with AMSOIL Signature Series Synthetic Motor Oil. It has a unique synthetic formulation and long-drain additive system that make it resistant to oxidation and neutralize acids for a long time.
AMSOIL’s Signature Series is guaranteed to provide superior engine protection, cleanliness, and performance over an extended drain interval. It provides peace of mind by allowing you to schedule oil changes around your schedule, while also lowering vehicle maintenance and oil waste
AMSOIL Cleans Up the Competition
Using AMSOIL’s Signature Series maintains a high total base number (TBN) throughout the oil’s life. It neutralizes acidic contaminants, keeping them suspended in the engine for maximum protection.
You can see why we believe the AMSOIL’s Signature Series Motor Oil is the superior synthetic oil on the market. Take a few quarts with you when you next have your oil changed and see for yourself.
