What is the difference between AMSOIL Signature Series and Mobil 1 motor oils?

AMSOIL Signature Series offers superior shear resistance, volatility, and acid-neutralizing capabilities compared to Mobil 1, making it the better choice for high-performance engines.

Comparing AMSOIL Signature Series and Mobil 1 Motor Oils

Performance enthusiasts often seek ways to enhance their vehicle's power. Turbocharging, supercharging, and other modifications are common methods. However, these upgrades demand high-quality motor oil to protect the engine from the additional power generated. Two top contenders in the synthetic motor oil market are AMSOIL Signature Series and Mobil 1. Let's delve into what each offers in terms of protection and performance.

Horsepower Protection

Increasing your engine's horsepower necessitates superior motor oil to handle the extra pressure. Without upgrading the oil, you risk inadequate protection from a thin oil film. AMSOIL Signature Series synthetic motor oil is renowned for its reliability and efficiency in high-performance engines. To ensure your engine can manage the power boost, equip it with premium motor oil.

When adding horsepower, the engine components work harder and generate more heat. The motor oil must be able to withstand these conditions without breaking down. AMSOIL Signature Series is specifically engineered to provide a strong protective film, ensuring that all moving parts are well-lubricated and protected against wear. Mobil 1 also offers high-performance oils, but AMSOIL's formulation provides an edge in extreme conditions.

What is the Shear Importance of Oil?

Shear is a critical factor in oil performance. High shearing forces can lead to viscosity loss, adversely impacting oil efficiency. This occurs when one layer of oil moves differently from another, such as between a piston and cylinder wall. Engines operating at high horsepower levels and RPMs are particularly vulnerable to shear, making it crucial to use oils that can resist these forces.

Oil's resistance to shear is vital. Shear forces break down the oil's molecular structure, reducing its viscosity. The type and amount of viscosity enhancers vary based on the oil and its application; some synthetic oils naturally resist shear without additional enhancers. Insufficient shear protection can result in significant engine damage due to friction and heat.

Shear occurs when one layer of fluid moves at a separate speed or direction from another layer within the same fluid.

AMSOIL vs. Mobil 1: Shear Resistance

AMSOIL synthetic motor oil uses resilient base oils and high-grade shear-resistant viscosity improvers, surpassing industry standards and outperforming Mobil 1 in preventing viscosity breakdown. When oil loses viscosity due to shear, it fails to protect crucial engine parts. AMSOIL is specifically formulated to provide maximum protection against shear forces.

Mobil 1, while a reputable and high-quality product, often uses a mix of synthetic and conventional base oils, which may not provide the same level of shear resistance as AMSOIL's fully synthetic formulations. This can be particularly important in engines that are heavily modified or operated under severe conditions. AMSOIL's advanced synthetic technology ensures that the oil maintains its viscosity even under extreme shear conditions, providing continuous protection to the engine.

Volatility and Cleanliness

High-performance engines require oil that combines cleanliness and volatility. Volatility measures an oil’s tendency to vaporize under extreme heat, while cleanliness involves preventing harmful deposits. Forced-induction engines generate intense heat, necessitating high volatility and total base number (TBN), which measures acid neutralization. Choosing the right oil blend ensures greater efficiency and longer engine life.

Volatility is crucial because as oil heats up, it can begin to vaporize. This not only leads to oil loss but also increases the formation of deposits inside the engine. AMSOIL Signature Series has a significantly lower volatility rate compared to Mobil 1, meaning it remains stable at higher temperatures and reduces oil consumption. This leads to a cleaner engine with fewer deposits and longer intervals between oil changes.

During TBN testing, AMSOIL showcased a remarkable 28% increase in acid-neutralizing capability compared to Mobil 1. This advantage aids in maintaining engine cleanliness and longevity over time.

AMSOIL vs. Mobil 1: Volatility and Cleanliness

In the competition between AMSOIL and Mobil 1, AMSOIL stands out with 38% superior volatility, making it a better choice for high-performance engines. AMSOIL also boasts 28% more acid-neutralizing power than Mobil 1, ensuring cleaner and longer-lasting engines. During TBN testing, AMSOIL demonstrated a remarkable 28% increase in acid-neutralizing capability compared to Mobil 1. This advantage helps maintain engine cleanliness and longevity.

Mobil 1's performance in volatility is good, but AMSOIL's lower volatility rates provide a distinct advantage. Lower volatility means less oil burn-off and fewer emissions, which is beneficial for both the environment and engine health. AMSOIL's advanced formula also includes superior detergents that keep engines cleaner by preventing the formation of sludge and varnish.

Long-Term Engine Protection

One of the primary reasons to invest in high-quality motor oil is to ensure long-term engine protection. Both AMSOIL Signature Series and Mobil 1 offer protection, but the differences in their formulations can affect long-term engine health.

AMSOIL vs. Mobil 1: Long-Term Protection

AMSOIL's formulation focuses on providing maximum protection under extreme conditions. Its superior base oils and additives ensure that the oil maintains its protective qualities over extended periods. This makes AMSOIL an excellent choice for vehicles that undergo extended drain intervals. AMSOIL Signature Series is designed to last up to 25,000 miles or one year, whichever comes first, under normal driving conditions.

Mobil 1 also offers extended drain intervals but generally recommends changing the oil every 15,000 miles or one year. While Mobil 1 is a high-quality oil, the longer interval and higher performance protection offered by AMSOIL give it an edge for those looking for maximum engine longevity.

Environmental Impact

With growing concerns about environmental sustainability, the choice of motor oil can also impact the environment. Synthetic oils generally offer better environmental benefits compared to conventional oils due to their longer life and lower volatility.

AMSOIL vs. Mobil 1: Environmental Impact

AMSOIL's lower volatility means fewer emissions and reduced oil consumption. Additionally, the extended drain intervals reduce the amount of used oil that needs to be disposed of, contributing to less environmental waste. Mobil 1 also offers environmental benefits with its synthetic formulations but falls short of AMSOIL's superior performance in this area.

Cost vs. Value

While synthetic motor oils tend to be more expensive upfront compared to conventional oils, they offer better value over the long term due to their extended drain intervals and superior engine protection.
