Smashing the Industry Standard

A New Level of Protection and Performance on the Horizon

The new Signature Series, XL and OE formulations launching this fall place our passenger car motor oil (PCMO) line ahead of the game.

The lubrication industry is rife with challenges, and the PCMO segment of the industry is no exception. Evolving engine technologies and tightening regulations drive new specifications, pushing motor oil companies to update their formulations to meet the latest demands. AMSOIL has once again cleared the path and found the most innovative solutions.

The Background

New regulations on fuel economy and emissions have pushed the automotive industry to develop smaller, more efficient engines. The prominence of direct injection (GDI) and turbochargers employed to meet rising corporate average fuel economy (CAFE) standards is placing new burdens on motor oil. Low-speed pre-ignition (LSPI) and increased engine temperatures are two of the more serious challenges to arise from the use of GDI and turbos.

Two new gasoline engine oil specifications have been developed to address these issues:

  • dexos1® Gen 2 [General Motors (GM)*] – expected to be released late August 2017
  • API SP/ILSAC GF-6 – expected to be released Fall 2019

After months of vigorous testing, we’ve produced new formulations that far surpass the latest standards and add another level of performance and protection to an already solid foundation.

Signature Series Synthetic Motor Oil (ASM, ALM, AZO, ASL,ATM, AZF, AMR)

Improving Signature Series was a challenge, but the results prove the new formulation blows the doors off the latest industry standards. Capitalizing on its firmly established success, our upgraded Signature Series motor oil provides enthusiasts with maximum protection and performance. The new formulation will become available in September or when current inventory is depleted.

OE Synthetic Motor Oil (OEZ, OEM, OEF, OET)

OE Synthetic Motor Oil delivers 100 percent synthetic engine protection for advanced automotive technology, including turbochargers and direct injection. It’s specifically formulated for the longer drain intervals recommended by original equipment (OE) manufacturers. OE is favored by mechanics and drivers seeking peace-of-mind protection and exceptional value in synthetic motor oil.

Top Rating - Perfect Score

LSPI is a hot topic in the lubricant industry. Auto manufacturers need to extract every bit of fuel economy from the vehicles they produce in order to meet increasingly stringent government regulations. Manufacturers can make fuel-economy gains in today’s vehicles by adjusting vehicles’ programming, but those changes would also almost guarantee LSPI would occur. LSPI’s often disastrous effects (see image) are one of the driving forces in the scramble to create the new motor oil specifications, API SP/ILSAC GF-6 and GM dexos1 Gen 2. To gain about 10 percent more fuel economy, auto manufacturers will eventually reprogram their vehicles to maximize mpg, inviting LSPI and relying on motor oil to prevent catastrophic results.

While we expect this switch will be a couple of years out yet, we have dedicated considerable resources to confront the problem. The testing has concluded and the results are in: all AMSOIL synthetic motor oils provided 100 percent protection against LSPI in the engine test required for the GM dexos1 Gen 2 specification.

This specific test records an oil’s ability to prevent LSPI. Five LSPI events can occur before the motor oil fails. Signature Series, XL and OE Synthetic Motor Oil all passed with zero pre-ignition events, proving they provide outstanding protection for turbocharged direct-injected engines.
