New Motor Oil Specifications

New Motor Oil Specifications in Effect

The automotive industry’s latest specifications, ILSAC GF-6 and API SP, are now effective. AMSOIL is ahead of the game.

Original equipment manufacturers (OEMs) are under pressure to improve fuel economy and reduce emissions. As a result, most new engines today use some combination of turbochargers, direct-fuel injection and variable valve timing to deliver better fuel economy and increase horsepower.

The trend of lighter engine oils to achieve these goals continues with 0W-16 viscosities emerging in the market and 0W-12 and 0W-8 expected to follow. The industry has responded to these advanced engine technologies and ultra-light oil viscosities with two new oil specifications: ILSAC GF-6 and API SP.

The Split: GF-6A and B

The International Lubricant Standardization and Approval Committee (ILSAC) has set a new precedent in the passenger-car motor oil market by splitting its specification into two parts. One of the main differences between the two specifications is compatibility. See the chart below.

Both versions focus on wear protection, prevention of low-speed pre-ignition (LSPI) and improved engine cleanliness. However, GF-6B features a more stringent fuel economy test. Engine oils can easily be identified as ILSAC GF-6A or 6B by the API emblem on the front label of the packaging. A shield represents the GF-6B specification, while the traditional starburst indicates a GF-6A product. Both ILSAC specifications meet the industry-standard API SP specification which is most commonly found in owners’ manuals.

We Are Ready

Our claims about using advanced technology aren’t just talk, and this specification update proves it once again. AMSOIL synthetic motor oils already meet or exceed the new industry standards and require no change in formulation. This is not the first time we’ve been in this position. While the competition works on making major formulation adjustments, we are ready. Our product labels will soon feature the new specifications as inventories of current packaging are depleted.

What Does Viscosity Mean and Its Importance?

How does viscosity affect your engine, mileage and performance?

Motor oil viscosity is the measure of its resistance to flow. Low-viscosity oil (e.g. 0W-20) flows faster than high-viscosity oil (e.g. 20W-50).

To illustrate, think of water and honey. When poured from a container, water flows much faster than honey.

New ILSAC GF-6A & GF-6B Motor Oil Specs For Modern Engines

ILSAC GF-6 and API SP specifications coming May 1. 

AMSOIL is already ahead of the game.

Original equipment manufacturers (OEMs) are under pressure to improve fuel economy and reduce emissions. As a result, most new engines today use some combination of turbochargers, direct-fuel injection and variable valve timing to deliver better fuel economy and increase horsepower. The trend of lighter engine oils to achieve these goals continues with 0W-16 viscosities emerging in the market and 0W-12 and 0W-8 expected to follow.

We Are Already There

Our claims about using advanced technology aren’t just talk, and this specification update proves it. AMSOIL synthetic motor oils already meet or exceed the new industry standards and require no change in formulation. This is not the first time we’ve been in this position. While the competition works on making major formulation adjustments, we just have to update our labels. The new specifications are not allowed to be displayed on labels until May 1, 2020. Expect to see updated AMSOIL labels then.

The Big Split

The International Lubricant Standardization and Approval Committee (ILSAC) recently set a new precedent in the passenger-car motor oil market by splitting its specification into two parts: 

GF-6A – backward compatible, provides protection for a variety of older and newer engines.


GF-6B – not backward compatible, for use in select new vehicles. 

Both versions focus on wear protection, prevention of lowspeed pre-ignition (LSPI) and improved engine cleanliness. However, GF-6B features a more stringent fuel economy test. Engine oils can easily be identified as ILSAC GF-6A or 6B by the API emblem on the front label of the packaging. A shield will represent the GF-6B specification, while the traditional starburst will indicate a GF-6A product. Both ILSAC specifications meet the industry-standard API SP specification which is most commonly found in owners’ manuals.

AMSOIL Signature Series

Signature Series: Maintains Protective Viscosity

The main bearings in your vehicle rely on an oil film thinner than a sheet of paper. When motor oil loses viscosity due to a process called shear, it can fail to provide the required level of wear protection.

Shear (often called mechanical shear) occurs when one layer of oil moves in the opposite direction of another layer of the same oil. This often occurs between the piston and cylinder wall. These two oil films move in opposite directions under intense heat and pressure.

AMSOIL synthetic motor oil features naturally shear-resistant base oils combined with top-tier viscosity improvers to withstand extreme heat and shearing forces. In fact, Signature Series fights viscosity breakdown better than the competition*, providing superior protection of pistons, cams and bearings.

Signature Series stands up to the potentially devastating effects of viscosity breakdown and provides maximum engine protection.

Signature Series Keeps Engines Cleaner Than Other Synthetic Motor Oils

AMSOIL Signature Series

In general, the higher an oil’s TBN, the better its ability to neutralize contaminants such as combustion by-products and acidic materials. Higher TBN oils neutralize a greater amount of acidic material, which results in longer oil life and cleaner engines.

TBN levels decrease as the oil remains in service. When the level reaches a point where it can no longer protect against corrosion, the oil must be changed.

The TBN Test

The Total Base Number Test (ASTM D2896) uses a series of chemical reactions to measure the alkaline additives in a motor oil. We recognize the value of formulating motor oils with high TBN, and AMSOIL Signature Series Synthetic Motor Oil features the highest TBN of the oils tested.

AMSOIL Signature Series is fortified with a heavy treatment of detergent additive and it delivers 30% more acid neutralizing power1 than Mobil 1, and 36% more than Royal Purple, helping engines to stay cleaner, longer.

The AMSOIL Advantage

AMSOIL synthetic lubricants feature a large dose of quality additives that consistently deliver high TBN for the life of the oil. They neutralize acidic contaminants and keep them in suspension to maximize engine protection. AMSOIL lubricants use detergent and dispersant additives to significantly reduce sludge and carbon deposit formation. In the Total Base Number Test (ASTM D2896), AMSOIL Signature Series 5W-30 Synthetic Motor Oil demonstrated the highest TBN of the oils featured in the test, helping it deliver reliable protection for extended drain intervals.

AMSOIL Signature Series and Turbochargers

AMSOIL Signature Series Protects Turbochargers

The turbocharger/direct fuel injection combo has emerged as automakers’ favored choice for producing powerful engines and meeting government fuel-economy requirements. The increased airflow turbos generate enables an engine to burn more fuel and produce more power, but this power comes at a cost. The tremendous heat and stress turbos create cause some oils to break down and form harmful bearing deposits through a process known as turbo coking. Over time, turbos can suffer reduced performance or fail altogether.

How Turbos Could Slow You Down

The deposits common to turbochargers can lead to:

• Blocked oil passages, oil starvation and eventual failure
• Reduced turbine speed – resulting in lower boost pressures, reduced performance and poor efficiency
• Oil breakdown and oil burning
• Expensive turbo rebuild or replacement 

The GM Turbo Coking Test

The Turbo Coking Test was designed to simulate the extreme operating conditions of a turbocharged engine. It evaluates a motor oil’s ability to resist deposit buildup in the oil passages and bushings of a turbocharger. Temperature increases within the turbo and the weight of any deposits are recorded.   

Test Parameters

Engine   -  2012 GM 1.4L

Duration   -  2,000 cycles of extreme heat soaks – approximately 537 hours

Measures   -  A motor oil’s ability to resist deposits in a turbocharger’s oil passages and bushings

Simulates   -   High-heat operation of a turbocharged engine 

Requirement   -  Temperature change within the turbocharger limited to 13 percent

Signature Series protects turbochargers 72% better than required by GM dexos1® Gen 21

The GM Turbo Coking Test requires an oil to limit the temperature change within the turbocharger to 13 percent or less to pass the test. Signature Series limited the temperature increase to only 3.6 percent, controlling heat and proving it protects against deposits common to high-temperature engine environments.

AMSOIL Signature Series Battles Sludge

AMSOIL Signature Series Battles Engine Sludge

Synthetic motoroil

The health of your engine depends on motor oil circulating quickly and efficiently through the system, but sticking components and obstructed passages inhibit motor oil from lubricating, cooling and protecting your engine. Engine “sludge” occurs when oxidized oil and contaminants build up on engine surfaces. It can restrict the flow of oil to the point of engine failure and costly repairs.

Sludge: Where It Starts & How It Ends

The valve cover and oil pan are generally the first areas sludge appears.
The oil pick-up tube screen is often the next spot it accumulates, impeding oil flow through the system.
What begins as a thin film of lacquer or varnish deposits eventually bakes into an expensive mess.

The Sequence VG Engine Test

Engine failures due to sludge are often caused by a clogged pick-up tube screen – the motor is effectively starved of oil. The Sequence VG Engine Test determines how well an oil resists sludge formation and keeps the lubricant flowing freely throughout the system. The test is required for API SN PLUS – a specification recommended by most domestic vehicle manufacturers.

TEST PARAMETERS

Engine

Ford* 4.6L V-8 

Duration

216 hours

Measures

Sludge and varnish deposits, piston ring sticking, clogged oil pump screens and roller pin wear

Simulates

Taxi, delivery or commuter vehicle service

Requirement

Oil pick-up tube screen limited to 10 percent blockage

The Results

Signature Series Synthetic Motor Oil was subjected to the Sequence VG to measure its ability to prevent sludge. As expected, Signature Series produced an oil pick-up tube screen virtually free from sludge (see image). Our unique combination of detergents and high-quality base oils control oxidation and sludge to keep engines clean and efficient. 

Signature Series has 50 percent more detergents1 to help keep oil passages clean and promote oil circulation. It provides 90% better protection against sludge2.

Cold-Temperature Performance is not Just Reserved for Sub-Zero Conditions

Startup lubrication is directly affected by a lubricant's cold-flow ability, and the impact is felt at higher temperatures than most consumers realize. An oil’s cold-temperature performance refers to its ability to flow when the engine is cold, or below typical operating temperature (212°F), and not simply to what feels cold to humans – even some summer days can be cold to an engine.

Pour point has been defined as the lowest temperature at which a motor oil will continue to flow under prescribed conditions. ASTM D97 spells out the standardized procedure for determining an oil’s pour point. After heating it to 45°C (113°F) the sample is slowly cooled and tilted sideways every time the temperature drops 3°C (5°F). When the oil stops flowing it has reached the pour point.

AMSOIL synthetic motor oils have lower pour points and better cold-cranking capabilities than petroleum-based products. Long after petroleum oils have solidified, AMSOIL synthetic motor oils continue to flow.

The problems with cold weather go beyond this, however. Motor oils really need to be heated well above the pour point to achieve the desired pumping viscosity. Even at just below freezing (32°F), motor oil can become difficult to pump into the engine. It sits in the pan while the friction from moving parts heats the engine and conducts this heat down into the pan. As you can imagine, this lack of oil in an engine with fast moving parts has consequences. Cold-weather start-ups are a leading cause of engine wear.

AMSOIL OE 0W-20 Synthetic Motor Oil (OEZ) is now available in gallon containers.

AMSOIL Adds 700-Hour Limit to Signature Series Drain Interval

Because a motor oil’s service life can be greatly affected by vehicle operating conditions, AMSOIL provides definitions for normal and severe service and recommends corresponding drain intervals for each. One of the conditions used to identify severe service is “excessive idling.” Because this term is somewhat ambiguous, AMSOIL is adding a 700-hour limitation to its Signature Series Synthetic Motor Oil drain interval for vehicles subjected to excessive idling. In normal service, Signature Series is recommended for up to 25,000 miles, 700 hours of operation or one year, whichever comes first. In severe service, Signature Series is recommended for up to 15,000 miles, 700 hours of service or one year, whichever comes first.
