AMSOIL Preferred Customer Program

Original equipment manufacturers (OEMs) are under pressure to improve fuel economy and reduce emissions. As a result, new engines feature turbocharging, direct-fuel injection and variable valve timing. This combination delivers on fuel economy and emissions while increasing horsepower.

The trend of lighter engine oil viscosities to achieve fuel economy continues with viscosities such as 0W-16 emerging in the market and 0W-12 and 0W-08 expected to follow. Ultra-light viscosities require special attention, so the industry responded with the ILSAC GF-6 and API SP engine oil specifications.

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. At AMSOIL, we’ve been hard at work preparing for these future OEM updates.

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

The complete AMSOIL motor oil lineup has been upgraded to meet these new challenges.
