AMSOIL Signature Series Synthetic Motor Oil is excellent for use in all types of gasoline-fueled vehicles. It is recommended for all domestic and foreign vehicles requiring any of the listed performance specifications:
• API SN, SM
• Ford WSS-M2C931-C (Mustang)
Protects Your Engine: AMSOIL Signature Series Synthetic Motor Oil provides outstanding anti-wear protection. It develops a strong fluid film that keeps metal surfaces separated while its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. In the Sequence IIIG test, which is normally run for 100 hours, AMSOIL Signature Series Synthetic Motor Oil delivered outstanding wear protection for the camshaft and lifters, even after doubling the test interval to 200 hours. For details, see the Double-Length Sequence IIIG Engine Test Technical Study (G3320).
AMSOIL, the leader in automotive synthetic lubrication, produced the world's first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, the First in Synthetics®, to do the best job protecting your engine.
AMSOIL Signature Series Synthetic Motor Oil develops a strong fluid film that keeps metal surfaces separated while its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. The Sequence IVA Engine Test, which must be passed to meet the industry-standard API SN specification, 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. We used Signature Series 0W-20, the lightest viscosity in the line, to further increase the severity of the test. AMSOIL Signature Series Synthetic Motor Oil provided 75 percent more engine protection against horsepower loss and wear* than required by the industry standard, extending the life of vital components like pistons and cams.
We armed Signature Series with an advanced detergent system that protects against harmful deposits and low-speed pre-ignition (LSPI). Most new engines feature gasoline direct injection (GDI), often combined with a turbocharger to boost power and improve fuel economy. These new technologies, when combined with a poorly formulated motor oil, promote LSPI and 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.
Original equipment manufacturers (OEMs) like GM* have addressed the issue by designing tests to determine a motor oil's ability to prevent LSPI. The GM test allows up to five LSPI events to receive a passing score. Signature Series Synthetic Motor Oil provided 100 percent protection against LSPI* - zero occurrences were recorded.
Our 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. 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.
We 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* by the GM dexos1® Gen 2 specification.
AMSOIL Signature Series Synthetic Motor Oil provides reserve protection, allowing you to go longer between oil changes if you choose up to 25,000 miles, 700 hours of operation or one year, whichever comes first*. Our 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.
Any brand of oil filter may be used with Signature Series Synthetic Motor Oil. For maximum convenience, however, use an AMSOIL Ea® Oil Filter. Made of fully synthetic media with greater filtering efficiency and dirt-holding capacity than conventional filters, Ea Oil Filters are recommended for 25,000 miles/12 months or 15,000 miles/12 months, depending on application, which coincides with Signature Series' once-a-year drain interval. While Signature Series' 12-month service life remains intact if a non-Ea Oil Filter is used, the filter must be changed according to its manufacturer's recommendations.
The extreme durability of Signature Series Motor Oil ensures your engine runs stronger, for longer. We installed Signature Series 5W-30 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 25,000 miles. 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 test.
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 482°F 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.
Signature Series Synthetic Motor Oil does not contain paraffins (wax) and stays fluid in temperatures of -58°F 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.
We 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 304°F, 100°F 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.

• Modified engines (non-stock), racing vehicles and vehicles using alternative fuels (E85, CNG, propane, etc.) are excluded from extended drain interval recommendations.
• Change at the vehicle manufacturer's recommended drain interval outside U.S. and Canada.
• AMSOIL Ea® Full-Flow Oil Filters are designed for extended drain intervals. Do not exceed 12,000 miles or one year with other brand filters unless longer intervals are recommended by the vehicle manufacturer. Always change filter when changing oil.
• Check oil regularly to maintain proper fill levels.
AMSOIL Ea Full-Flow Oil Filters stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea Full-Flow Oil Filters.

Re: Thank you - 2014 FORD MUSTANG 5.8L
Thank you Dave for sharing your thoughts. Use AMSOIL 25,000-Mile Ea Oil Filter (EAO11) to take advantage of the extended drain capabilities of the oil.Replied by Tech Admin
