Signature Series 0W-20 Synthetic Motor Oil

   Signature Series 0W-20 Synthetic Motor Oil

AMSOIL Signature Series Synthetic Motor Oil is AMSOIL’s top-tier product, designed for use in all types of gasoline engines. It utilizes advanced synthetic technology and premium additives to deliver superior engine protection. It withstands higher temperatures than typical motor oils and handles extreme stress in high-horsepower engines. Compared to other brands, AMSOIL Signature Series consistently delivers better test performance and superior engine protection.

Key Benefits

Extended Drain Intervals

AMSOIL Signature Series extends oil change intervals far beyond those of conventional oils. Its unique synthetic formulation resists oxidation and combats acidity from combustion byproducts, allowing it to maintain effectiveness over long periods.

Maximum Fuel Economy

Formulated for optimal fuel efficiency, AMSOIL Signature Series uses uniformly shaped synthetic molecules that minimize friction between metal surfaces. This contrasts with the inconsistent molecular structure of conventional oils. Additionally, friction modifiers further improve fuel economy compared to regular oils.

Ultimate Wear Protection

This oil forms an exceptionally strong film on engine components and includes advanced anti-wear additives to significantly reduce engine wear and maximize engine life.

Lower Maintenance Costs

With longer drain intervals and improved wear protection, AMSOIL Signature Series reduces the need for frequent oil changes and associated service costs. It helps maintain engine condition, resulting in long-term savings.

Low Oil Consumption

Due to its low volatility, AMSOIL Signature Series resists evaporation under high heat, meaning less oil loss and fewer emissions compared to standard oils.

Reduced Emissions

The oil is fully compatible with modern emission systems, including catalytic converters, and helps them operate efficiently, reducing tailpipe emissions and protecting the environment.

Extreme Temperature Performance

This oil resists thermal breakdown, evaporation, and viscosity loss in high heat, while remaining fluid in freezing conditions. This ensures easy engine starts and proper circulation even in cold climates.

Cleans the Engine

AMSOIL Signature Series includes powerful detergents and dispersants that prevent sludge and carbon buildup better than conventional oils. It keeps the engine cleaner and improves long-term performance (see cylinder cleanliness results after 200-hour test).

Applications

AMSOIL Signature Series is ideal for most gasoline engines and meets or exceeds the following specifications:

• API SP (Resource Conserving), SN PLUS, SN…

• ILSAC GF-6A, GF-5, GF-4…

• ACEA A1/B1

• Ford WSS-M2C947-B1, WSS-M2C947-A, WSS-M2C962-A1

• Chrysler MS-6395

• GM dexos1™ Gen 3 (supersedes dexos1 Gen 2 and 6094M)

Compatibility with Other Oils

AMSOIL Signature Series is compatible with conventional and synthetic motor oils. However, mixing with other oils reduces its performance and lifespan. AMSOIL does not recommend extended drain intervals in such cases and advises against using any oil additives or aftermarket treatments.

Available Sizes

• 1 Quart (0.946 liters)

• 1 Gallon (3.784 liters)

Service Life

AMSOIL guarantees the following service life for gasoline engines:

• Normal Service – Up to 40,000 km (25,000 miles) or 1 year, whichever comes first

• Severe Service – Up to 24,000 km (15,000 miles) or 1 year, whichever comes first

For non-gasoline engines, service intervals depend on oil properties and manufacturer recommendations.

Severe Service Conditions Include:

• Short trips under 16 km (10 miles)

• Turbocharged engines

• Fleet vehicles or frequent commercial use

• Heavy traffic or stop-and-go driving

• First-time use of AMSOIL in vehicles over 160,000 km without engine flush

• Frequent towing

• Driving in dusty environments

Caution

Extended drain intervals are not recommended for modified engines or vehicles using E85 fuel. In such cases, follow the vehicle manufacturer’s recommended oil change interval.
