Annual Oil Changes with AMSOIL Extended-Life Motor Oil

AMSOIL Extended-Life 100% Synthetic Motor Oil line is overbuilt so road warriors can confidently drive up to 20,000 miles (32,000 km) or one year between oil changes (whichever comes first).

AMSOIL Extended-Life Motor Oil features a proprietary combination of advanced synthetic base oils and a boosted additive package that promotes cleanliness and prolonged engine life.

Resists Oil Breakdown

Some oils break down and significantly increase in viscosity (becoming thicker) after extended periods of high temperature operation. These changes can cause excessive oil consumption, engine deposits, accelerated wear and difficult cold starts.

AMSOIL Extended-Life Motor Oil maintains its fluidity (viscosity) under extended high-temperature operation to resist oil breakdown and ensure continued protection.

Low-Speed Pre-Ignition protection

Low-speed pre-ignition (LSPI) is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition, which can destroy pistons and connecting rods.

To maintain performance while meeting increasingly challenging emissions standards, many newer engines feature gasoline direct injection (GDI) coupled with a turbocharger. Both technologies can increase the possibility of LSPI events.

AMSOIL Extended-Life Motor Oil features unique chemistry designed to protect engines against the harmful effects of low-speed pre-ignition.

Keeps Engines Clean

Running conventional motor oils for extended periods of time can cause sludge, corrosion and carbon deposits that lead to increased engine wear and reduced performance,

AMSOIL Extended-Life Motor Oil is fortified with a boosted additive package that far surpasses the leading industry standards in neutralizing acids and resists sludge, corrosion and carbon deposits to keep your engine clean and help maintain its performance.

Extended engine protection

In addition to the convenience of extended oil drain intervals, AMSOIL Extended-Life 100% Synthetic Motor Oil provides peace of mind so you can rest easy knowing your vehicle is receiving premium protection for the long road ahead.
