AMSOIL EXTENDED-LIFE 0W-20 100% SYNTHETIC MOTOR OIL

AMSOIL Extended-Life 0W-20 100% Synthetic Motor Oil delivers 20,000-mile drain intervals and 37% more cleaning power than AMSOIL OE Synthetic Motor Oil, making it a smart upgrade for drivers who want extended protection without sacrificing engine cleanliness.

Modern gasoline direct-injection (GDI) and turbocharged engines run hotter, build more combustion byproducts, and place greater stress on motor oil than previous engine designs. Oil that can't maintain its viscosity over long service intervals leads to excessive consumption, deposit buildup, and accelerated wear. Vehicles like the Toyota Camry, Honda CR-V, Ford F-150, Jeep Grand Cherokee, and Subaru Outback that specify 0W-20 need a synthetic oil that holds up well past the 5,000-mile mark.

RESISTS OIL BREAKDOWN OVER EXTENDED INTERVALS
Some oils thicken significantly after prolonged exposure to high operating temperatures. That viscosity change increases oil consumption, promotes deposit formation, and makes cold starts harder on bearings and cylinder walls. AMSOIL Extended-Life 0W-20 maintains its fluidity under extreme conditions, with a viscosity index of 168 (ASTM D2270) that reflects strong resistance to thermal thinning and shear. The high-temperature/high-shear viscosity measures 2.7 cP at 150°C (ASTM D5481), confirming the oil holds a protective film even in the most demanding operating conditions inside a turbo GDI engine.

PROTECTS AGAINST LOW-SPEED PRE-IGNITION
LSPI is the spontaneous ignition of the fuel-air mixture before spark-triggered combustion, and it can destroy pistons and connecting rods in turbocharged GDI engines. Most newer vehicles from Honda, Toyota, Ford, GM, Hyundai, and Kia use this engine architecture. AMSOIL Extended-Life 0W-20 features chemistry specifically formulated to guard against LSPI events, providing critical protection in engines where the risk is highest. This matters in real-world driving conditions where low-rpm, high-load situations, such as merging or accelerating from a stop, can trigger LSPI.

KEEPS ENGINES CLEAN WITH A BOOSTED ADDITIVE PACKAGE
AMSOIL Extended-Life 0W-20 delivers 37% more cleaning power compared to AMSOIL OE Synthetic Motor Oil. The boosted detergent and dispersant additive package neutralizes acids and resists sludge, corrosion, and carbon deposit formation throughout the entire drain interval. That cleaning performance matters over a 20,000-mile service life, where lesser oils allow contaminants to accumulate and coat internal engine surfaces. A Total Base Number of 10.7 (ASTM D2896) indicates strong acid-neutralizing reserve, which keeps the oil effective at controlling corrosion and deposit formation well into extended use.

OUTSTANDING COLD-WEATHER PERFORMANCE
The 0W-20 viscosity grade is already optimized for cold climates, but the quality of the base oils and additives determines how well the oil actually flows at startup. AMSOIL Extended-Life 0W-20 has a cold-crank simulator viscosity of 5,207 cP at -35°C (ASTM D5293) and a pour point of -42°C/-44°F (ASTM D97). For drivers in Minnesota, Wisconsin, the northern Rockies, or anywhere winter temperatures routinely drop below zero, this oil circulates quickly at startup and reduces the dry-start wear that shortens engine life.

REDUCES MAINTENANCE COSTS FOR PERSONAL AND FLEET VEHICLES
Extended drain intervals up to 20,000 miles or one year in normal service cut the number of oil changes per year significantly. For fleet managers running Toyota Tacomas, Honda Civics, Ford Escapes, or Hyundai Tucsons, fewer oil changes mean less downtime, lower parts costs, and reduced waste oil disposal. Business owners and daily commuters benefit equally from the convenience and savings.

Specifications and Compatibility
AMSOIL Extended-Life 0W-20 (XLZ) meets the following specifications: API SQ (Resource Conserving), SP, SN Plus; ILSAC GF-7A, GF-6A, GF-5; GM dexos1 Gen 3 (supersedes dexos1 Gen 2 and 6094M); ACEA A1/B1; Chrysler MS-6395; Ford WSS-M2C947-A, WSS-M2C947-B1, WSS-M2C962-A1, WSS-M2C972-A1; and Honda HTM-06.

This oil is compatible with conventional and other synthetic motor oils. Mixing with other oils will shorten its life expectancy and reduce performance. Aftermarket oil additives are not recommended for use with this product.

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 vehicles, excessive idling, frequent towing, hauling, plowing, or driving in dusty conditions. Modified (non-stock) engines, racing vehicles, and vehicles using alternative fuels (E85, CNG, propane) are excluded from extended drain interval recommendations.

For best performance, use AMSOIL Oil Filters, which 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 the filter when changing oil. Check oil regularly to maintain proper fill levels.
