AMSOIL Smashes the Industry Standard – Again

A New Level of Protection & Performance on the Horizon

A potentially catastrophic problem is surfacing in today’s engines. Here’s how AMSOIL has solved it.

 

Original equipment manufacturers (OEMs) have been aggressively downsizing engines to meet strict fuel-economy and emissions standards while improving power and torque. Most new engines today use some combination of turbochargers, direct-fuel injection and variable valve timing to make more power than their larger counterparts while delivering improved fuel economy.

This scenario seems like all up-side for drivers. But today’s smaller, hotter-running engines pose significant challenges to lubricants. The latest is a phenomenon called low-speed pre-ignition (LSPI), also known as “super knock,” which can destroy pistons and connecting rods.

Low Speed High Torque causes LSPI Super Knock in Newer Engines

Why Low Speed Pre-Ignition (LSPI) or “Super Knock” is Becoming an Issue

 WHAT IS LSPI?

Vehicle manufacturers know this is an issue and have programmed vehicle software to avoid LSPI-inducing conditions. Doing so, however, limits fuel efficiency. To extract maximum efficiency from their advanced power plants, OEMs will soon implement software updates that will increase the risk of LSPI. After the software installation, engines without the protection of a motor oil formulated to combat LSPI will be at greater risk of severe damage. AMSOIL has been hard at work preparing for these future OEM updates.

Proving it can protect turbocharged direct-injected engines, AMSOIL provided 100 percent protection against LSPI in the engine test required by the GM dexos1® Gen 2 specification.
