How Does Signature Series Protect Against Engine Wear?
AMSOIL Signature Series 100% Synthetic Motor Oil contains robust anti-wear additives and develops a strong fluid film that keeps metal surfaces separated to reduce wear in metal-to-metal contact regions for maximum engine life. AMSOIL Signature Series Synthetic Motor Oil extends the life of vital components like pistons and cams by providing 75 percent more engine protection against horsepower loss and wear than required by the industry standard! How is Signature Series Tested? Signature Series Synthetic Oils are tested via the Sequence IVA Engine Test, which must be passed to meet the industry-standard API SN specification. This test simulates extended periods of stop-and-go driving. For 100 hours, the test engine cycles between 50 minutes of idling and 10 minutes of elevated rpm – conditions that encourage engine wear. The camshaft is then measured for wear in 84 locations and an average score is determined. To further increase the severity of the test, AMSOIL uses Signature Series 0W-20, the lightest viscosity in the line. |

Protects Pistons from Low-Speed Pre-Ignition
Most modern engines feature gasoline direct injection (GDI), often combined with a turbocharger to boost power and improve fuel economy. If combined with a poorly formulated motor oil, this new engine technology promotes Low-Speed-Pre-Ignition (LSPI) that can threaten engine operation. LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. It occurs in today's advanced engines and is much more destructive than typical pre-ignition. A properly formulated motor oil is critical for protecting your engine. This is why AMSOIL designed Signature Series with an advanced detergent system that protects against harmful deposits and low-speed pre-ignition. Original equipment manufacturers (OEMs) like GM* have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. Signature Series Synthetic Motor Oil achieved 100 percent protection against LSPI in the engine test required by the GM dexos1 Gen 2 specification - zero occurrences were recorded throughout five consecutive tests. |
Protects Turbochargers
The tremendous heat and stress turbos create can cause some oils to break down and form harmful bearing deposits through a process known as turbo coking. Over time, turbos can suffer reduced performance or fail altogether. AMSOIL's unique synthetic formulation is inherently stable to resist oxidation and neutralize acids. Signature Series Motor Oil provides outstanding protection against deposits common to high-temperature engine environments. AMSOIL challenged Signature Series to the GM Turbo Coking Test, which consists of 2000 cycles of extreme heat soaks. An oil must limit the temperature change within the turbocharger to 13 percent or less to pass the test. Signature Series limited the temperature increase to only 3.6 percent, protecting the turbocharger 72 percent better than required 2 by the GM dexos1® Gen 2 specification. |
Extends Drains: Protection Guaranteed
AMSOIL Signature Series Synthetic Motor Oil provides reserve protection, allowing you to go longer between oil changes if you choose – up to 40,000 km, 700 hours of operation or one year, whichever comes first*. AMSOIL's unique synthetic formulation and long-drain additive system are inherently stable to resist oxidation and neutralize acids over longer periods. Signature Series is designed to deliver outstanding engine protection, cleanliness and performance over extended drain intervals – guaranteed. It provides peace of mind so you can fit oil changes into your schedule.

Preserves Horsepower
The extreme durability of Signature Series Motor Oil ensures your engine runs stronger, for longer. AMSOIL installed Signature Series 5W-20 Synthetic Motor Oil in a Ford* F-150 with a new 3.5L Ecoboost engine to test its ability to protect turbocharged direct-injection (TDGI) engines from torque and horsepower loss during extended drain intervals up to 40,000 km. Power sweeps were done at the beginning and end of the test to evaluate horsepower and torque retention. As the graph shows, Signature Series helped maintain engine performance throughout the 100,000 mile (160,000 km) test.

Limits Oil Consumption
Signature Series has a uniform molecular structure that limits evaporation and keeps it where it's needed most – protecting your engine. Volatility (burn-off) occurs when oil gets hot, causing lighter molecules to burn off or evaporate. This leads to oil thickening, additive imbalance, higher emissions and oil consumption. The NOACK Volatility test is the industry standard for evaluating motor oil high temperature evaporation. It measures the percentage of burn-off after a motor oil is placed under constant airflow at 482ºF for 1 hour. A lower number indicates a better resistance to evaporation. Signature Series falls far below the API limit for volatility, reducing the need for frequent oil top-offs and limiting vehicle emissions.

Easier Cold-Starts
Signature Series Synthetic Motor Oil does not contain paraffins (wax) and stays fluid in temperatures of -58ºF and lower. Extreme cold causes other motor oils to thicken, starving vital moving parts of lubrication, accelerating wear and even preventing vehicles from starting. Signature Series provides 66 percent better cold-temperature performance for easier starting, better fuel economy, improved oil flow (as seen below) and reduced wear.

Maintains Protective Viscosity
AMSOIL formulated Signature Series with superior thermal durability that resists breakdown better than conventional and synthetic motor oils. The Sequence IIIH Test uses the Chrysler 3.6L Pentastar engine to evaluate a motor oil's ability to resist the damaging effects of heat. The test is conducted with oil temperatures of 304ºF, 100ºF hotter than normal operation, to accelerate oil thickening and deposits. Despite the extreme conditions, Signature Series kept pistons clean and held thickening to only 6 percent, a minimal amount compared to the proposed specification limit of 150 percent. This stay-in-grade performance helps maintain maximum power and fuel economy while also ensuring advanced technologies like variable valve timing (VVT) operate as designed throughout the entire drain interval.
