Enhanced Protection for Peace of Mind and Convenience
AMSOIL Extended-Life 0W-20 100% Synthetic Motor Oil is overbuilt for road warriors so you can confidently drive up to 20,000 miles (32,000 km) or one year, whichever comes first, between oil changes. A proprietary combination of advanced synthetic base oils and a boosted additive package promotes cleanliness and prolonged engine life.
Key Benefits
- Drive up to 20,000 miles or one year between oil changes
- Resists oil breakdown under extreme high-temperature conditions
- Protects against low-speed pre-ignition (LSPI) in GDI turbo engines
- Boosted additive package neutralizes acids and resists sludge and deposits
- Maintains viscosity stability for consistent protection
- Compatible with conventional and other synthetic motor oils
- API SQ Resource Conserving and GM dexos1 Gen 3 approved
Built to Resist Breakdown and Protect Against LSPI
Extended-Life Synthetic Motor Oil maintains its fluidity (viscosity) under extreme conditions. Some oils break down and significantly increase in viscosity after extended periods of high-temperature operation, causing excessive oil consumption, engine deposits, accelerated wear, and difficult cold starts. AMSOIL Extended-Life resists oil breakdown, ensuring protection in extreme temperatures.
AMSOIL Extended-Life features unique chemistry to protect against low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition, which can destroy pistons and connecting rods in modern GDI turbocharged engines.

Frequently Asked Questions
Under normal service in personal vehicles, you can drive up to 20,000 miles (32,000 km) or one year, whichever comes first. Under severe service (commercial/fleet vehicles, excessive idling, frequent towing/hauling), the interval is up to 12,000 miles (20,000 km) or one year.
Yes. AMSOIL Extended-Life 0W-20 features unique chemistry specifically formulated to guard against low-speed pre-ignition (LSPI), which is a concern in modern gasoline direct injection (GDI) engines often coupled with turbochargers.
Yes, Extended-Life is compatible with conventional and other synthetic motor oils. However, mixing other oils will shorten the oil's life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Many modern passenger vehicles from GM, Ford, Chrysler, Toyota, Honda, and others specify 0W-20 for improved fuel efficiency and cold-weather performance. Check your owner's manual to confirm the correct viscosity grade for your vehicle.
