XL 0W-20 Synthetic Motor Oil

   XL 0W-20 Synthetic Motor Oil

Resists Oil Breakdown

AMSOIL XL (Extended Life) Synthetic Motor Oil maintains its lubricating properties (viscosity stability) even under harsh operating conditions such as prolonged high temperatures—conditions that typically degrade conventional motor oils. In such environments, oil viscosity often increases significantly, leading to higher oil consumption, increased engine deposits, more wear, and harder engine starts.

In the GM Oxidation and Deposit (GMOD) Test—performed on a 5.7L V8 engine at 100°C for 100 hours—AMSOIL XL demonstrated 64% better viscosity control compared to oils that fail the GM dexos1® Gen 2 “Breakdown 1” limit, proving its superior performance in high-heat conditions.

Protects Against LSPI (Low-Speed Pre-Ignition)

AMSOIL XL Synthetic Motor Oil features a unique chemical formulation that protects engines from LSPI, a condition where the air-fuel mixture ignites too early. LSPI commonly affects modern turbocharged gasoline direct injection (GDI) engines and can cause severe damage to pistons and cylinders.

AMSOIL XL has been specially formulated to reduce LSPI risk and has achieved a 100% pass rate in GM dexos1® Gen 2 testing, with zero LSPI events in five consecutive tests.

Cleans the Engine

AMSOIL XL is infused with high-quality additives, including detergents and dispersants, to maintain engine cleanliness. These additives help prevent sludge, neutralize acids (via high Total Base Number, TBN), and protect against corrosion and carbon buildup. The result is an engine that runs 25% cleaner, ensuring smoother performance and long-term reliability.

Extended Drain Interval Saves Money

AMSOIL XL is designed for extended oil change intervals—up to 19,200 km (12,000 miles) or 1 year, whichever comes first. This helps reduce maintenance costs, service time, and the environmental impact from used oil and emissions.

Improved Fuel Economy and Lower Emissions

AMSOIL XL (except for 10W-40) meets the API SP (Resource Conserving) standard, which focuses on fuel efficiency, low emissions, and compatibility with modern emissions control systems. It helps extend the lifespan of catalytic converters and supports eco-friendly driving.

Applications

AMSOIL XL (Extended Life) Synthetic Motor Oil is ideal for gasoline-powered vehicles requiring the following specifications:

0W-20 (XLZ):

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

• GM dexos1 Gen 2 (supersedes 6094M)

• ACEA A1/B1

• Chrysler MS-6395

• Ford WSS-M2C947-A

• ILSAC GF-6, GF-5, GF-4

• Fortified with detergents that exceed the dexos1 Gen 2 sulfated ash specification

Service Life

SERVICE LIFE
Normal Service – Up to 20,000 miles (32,000 km) or one year, whichever comes first, in personal vehicles not operating under severe service.
Severe Service – Up to 12,000 miles (20,000 km) or one year, whichever comes first. Severe service conditions include commercial or fleet ve-hicles; excessive idling; or frequent towing, hauling, plowing or driving in dusty conditions.
• 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 Oil Filters are designed for extended drain intervals. Do not exceed 12,000 miles (20,000 km) 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 Oil Filters stop smaller particles, flow more oil and last longer than regular filters.
For best performance, use AMSOIL Oil Filters.
