Perfect Pairing:Signature Series Motor Oil and Ea® Oil Filters

Combining premium motor oil with a premium oil filter is necessary for total engine protection.

Complete engine protection is a team sport. The long-term effectiveness of a quality motor oil is often hindered by poor filtration. At the same time, the superior capabilities of a premium oil filter remain unrealized when combined with a sub-par motor oil. A pairing of top-quality oil and filtration is required for best results, especially with the advanced technology found in modern vehicles.

Protecting the Latest Technology

Variable Valve Timing (VVT)

The majority of vehicles rolling off the assembly line today feature variable valve timing (VVT). Every component in the system must function properly in order to advance or retard valve timing at the correct intervals. The solenoid pictured, from a 3.5L Ford* EcoBoost* engine, contains openings .007 of an inch across, which is about the thickness of two sheets of paper. The slightest amount of deposits in these openings can restrict oil flow and negatively affect the system.

AMSOIL Signature Series Synthetic Motor Oil resists deposits and sludge, while the superior efficiency of Ea Oil Filters traps and holds any existing deposits that could compromise VVT components.

Turbochargers

Turbochargers are predicted to be in most new passenger cars/light trucks by 2020. This technology increases engine efficiency and performance, but at the cost of elevated engine temperatures. Low-quality motor oil increases the risk for high-temperature bearing deposits that lead to reduced turbocharger performance or failure.

Signature Series 5W-30 Synthetic Motor Oil protects against harmful deposits on turbochargers 4X better than Mobil 1® Extended Performance and 3.6X better than Royal Purple® in industry-standard testing**. AMSOIL Ea Oil Filters are engineered to maintain the higher oil flow rate of modern engines, sending the appropriate amount of filtered oil to the turbocharger’s vital bearing. Bearing clearances, in general, have become tighter, making filter efficiency even more important to prevent engine damage.

Tag Team Protection

Working in tandem, AMSOIL Signature Series Motor Oil and AMSOIL Ea Oil Filters provide complete engine protection. Signature Series Motor Oil withstands the rigors of extreme heat and resists deposits and sludge, while Ea Oil Filters provide the capacity and efficiency that today’s advanced engine components require.

The Long Run

Turbochargers and VVT systems are here to stay. AMSOIL products are uniquely positioned to meet the challenges they present.
Signature Series Synthetic Motor Oil

Provides 75 percent more engine protection against horsepower loss and wear than required by a leading industry standard ***
Maximum cleanliness

ADVANCED ENGINE TECHNOLOGY DRIVING CHANGES FOR GASOLINE OIL SPECIFICATIONS

Tightening fuel economy standards and the subsequent advances in engine technologies are pushing big changes in the passenger car motor oil (PCMO) market.

Increasingly strict regulations on fuel economy and emissions have pushed the automotive industry to develop smaller, more efficient engines. By 2020, industry experts predict that nearly every new vehicle will feature direct-injection technology (GDI), and the vast majority will be turbocharged (TGDI). The most recent corporate average fuel economy (CAFE) standards require a fleet-wide average of 54.5 mpg by 2025 in the United States, necessitating a 5 percent annual improvement.

These factors contribute to the following:

Severe engine knock, also called lowspeed pre-ignition (LSPI)
Increased engine temperatures • Compromised fuel injectors
Greater overall stress and dependence on engine oil

Two new gasoline engine oil specifications are in development to address these issues: General Motors’ (GM)* proprietary dexos1™: 2015 and API SP/ILSAC GF-6.

Controlling LSPI

Both specifications place a major focus on limiting the impact of low-speed pre-ignition (LSPI). This will be an essential feature of engine oil in the coming years. Similar to traditional engine knock, LSPI occurs when fuel/air spontaneously ignites prior to the spark ignition. The pressure created by this ill-timed combustion pushes down on the piston as the connecting rod and crankshaft work to move it upward. These conflicting forces can result in severe engine damage beyond that of typical engine knock. LSPI is an issue unique to newer turbocharged and GDI engines and occurs under low-speed and high-torque conditions. However, a properly formulated motor oil can prevent its effects.

Key Updates

dexos1™: 2015

GM’s second-generation dexos1 specification is a global specification that aims to standardize the quality of oil installed in GM vehicles regardless of location. Similar to the GF-6 specification, dexos1: 2015 will address fuel economy and LSPI. It will also include new tests unique to GM focused on oxidative thickening, piston deposits, turbocharger deposits and wear control. It is due to be released in late August 2017.

Designed for 2011 model-year and newer engines
Targets higher levels of performance in all areas

NEW DEXOS1: 2015 & ILSAC GF-6 SPECIFICATIONS

Low speed pre-ignition protection preventing severe engine damage
Added piston deposit prevention for fuel economy and horsepower retention
Improved turbocharger protection to prevent turbocoking and increase longevity
Increased wear protection for maintaining like-new performance
Increased sludge protection for cleaner engines

ILSAC GF-6

Replacing the ILSAC GF-5 specification, the primary focus of ILSAC GF-6 will be increased fuel economy, oil robustness and protecting GDI and TGDI engines from LSPI and timing-chain wear. The spec will be split into GF-6A and GF- 6B to accommodate the trend toward lower-viscosity oils. GF-6B will provide a new category of oil designed for newer vehicles that require low hightemperature/high-shear (HTHS) and viscosities of 0W-20 or less. GF-6 is expected to be released in mid-2019.

GF-6A is designed for current modelyear engines and older requiring a traditional viscosity oil
GF-6B is designed for newer engines requiring lower viscosity oil

API/ILSAC

The International Lubricant Standardization Approval Committee (ILSAC) is a partnership between U.S. and Japanese automobile manufacturers. ILSAC and the American Petroleum Institute (API) work in tandem to develop engine protection standards and fuel economy requirements. Oils displaying the API Certification Mark, or “Starburst,” meet these requirements.

New Testing

As new requirements are revealed and the technology evolves, many standardized engine tests are being overhauled or replaced. GF-6 will feature at least six new engine tests while dexos1: 2015 will gain five. The tests encompass issues from low-temperature valvetrain wear (GF-6) to turbocharger deposits (dexos1: 2015).

AMSOIL Prepared for Change

AMSOIL Dealers can be well-assured that we will be ready for the implementation of the new specs with top-performing synthetic formulations. Details will be unveiled in upcoming issues of AMSOIL Magazine.
