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. These changes can cause excessive oil consumption, engine deposits, accelerated wear and difficult cold-starts. AMSOIL Extended-Life Synthetic Motor Oil 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 Synthetic Motor Oil 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 Motor Oil provides peace of mind knowing your vehicle is getting premium protection and the convenience of extended drains.
