Enhanced Protection for Peace of Mind and Convenience

AMSOIL Extended-Life 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. AMSOIL Extended-Life protection delivers peace of mind and convenience.

Available in five viscosity grades — 0W-20, 5W-20, 5W-30, 10W-30, and 10W-40 — Extended-Life covers a wide range of passenger vehicle applications with API SQ certification and broad OEM approval coverage.

Choose Your Viscosity

Resists Oil Breakdown

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.

Protects Pistons from Low-Speed Pre-Ignition

AMSOIL Extended-Life Synthetic Motor Oil features unique chemistry to protect your engine against the harmful effects of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Most new engines feature gasoline direct injection (GDI), often coupled with a turbocharger. These technologies heighten the possibility of LSPI events, which can destroy pistons and connecting rods. AMSOIL Extended-Life is formulated to guard your engine from LSPI.

Keeps Engines Clean

Extended-Life Synthetic Motor Oil is fortified with a boosted additive package that neutralizes acids and resists sludge, corrosion, and carbon deposits. The extra protection built into Extended-Life provides peace of mind knowing your vehicle is getting premium protection and the convenience of extended drains.
