API SN PLUS & Pennzoil Platinum 0W-16

• The first, official license date for SN PLUS is set for May 1, 2018, however the specification is issued and there are both Pennzoil and Quaker State products that already meet this requirement and are on shelves including:
• Pennzoil Platinum Full Synthetic Motor Oils
• SAE 0W-20, SAE 5W-20, SAE 5W-30, and SAE 10W-30
• Pennzoil Platinum High Mileage Full Synthetic Motor Oils
• SAE 0W-20, SAE 5W-20, SAE 5W-30, and SAE 10W-30
• Pennzoil Gold Motor Oils

Shell has always provided oils suitable for direct injection engines. It is the combination of direct injection PLUS turbo charging (TGDI) that has necessitated the requirement for specifications like API SN PLUS. 0W-16 motor oils provide unique challenges in that the lower viscosity requires formulators to pay particular attention to engine wear control while maintaining tight control of oil volatility. The use of PurePlus base oils allow Pennzoil to formulate motor oils at the new, lower viscosity requirements while still maintaining excellent volatility control.

4. How does SN PLUS compare to its ACEA counter part, such as A5/B5? Does it have stricter rules?

ACEA A5/B5 is not a “counterpart” to API SN PLUS in that SN PLUS includes a newly developed LSPI (Low-Speed Pre-Ignition) test and limits to provide protection against this new phenomenon. In the future we expect ACEA to also include LSPI protection in their industry standards.

When new engine oil specifications are developed, the industry teams take great care to make sure older vehicle designs are protected as well. It’s important to consider that testing to evaluate fuel economy has been added to specifications where traditional tests for wear, oxidation, and corrosion remain. Behind the scenes during new specification development, as new engine tests are added to replace existing tests, there are further efforts to prove-out backwards serviceability. Each of these efforts present unique challenges for lubricant formulators. For example, although a reduced ZDDP level is necessary to protect catalytic converters, new and more effective ZDDP compounds are developed to provide comparable protection at lower treat rates. For LSPI protection, one formulating approach may be to reduce calcium levels where this can be balanced by substituting other additives to maintain effective detergency.

I engines pre-dated the original dexos1TM Gen 1 specification. Additionally, dexos1TM Gen 2 products provide additional protection for turbocharged, GDI (TGDI) engines and are fully backwards compatible with previous dexos1TM and earlier GM specifications. Additional additives/performance boosters are not required for older vehicles.

7. Will SN PLUS have an advanced timing chain wear component to the certification as well or is it only geared towards LSPI prevention in GDI and TGDI applications.

Although SN PLUS does not include a new timing chain wear test in its requirements, the new GF-6 category under development will indeed have a timing chain wear test included along with the LSPI test currently in SN PLUS. The timing of test development efforts for industry categories allowed the pull ahead of SN PLUS including LSPI, which will be closely followed by GF-6.

Both provide specifications for lubricants in the traditional areas of wear, oxidation, and corrosion as well as the new TGDI issue of LSPI. However, they do not share all of the same engine tests. For example, the dexos1TM Gen 2 specification includes a proprietary LSPI test that was developed by GM. SN PLUS has an LSPI test that was developed by Ford in cooperation with industry input and as part of the ASTM standardization process.

Zinc dialkyldithiophosphates (ZDDP) are the most common anti-wear additives used in motor oils. The phosphates in ZDDP are the active ingredients for delivering wear protection while the Zinc provides a stable, convenient, cost effective means for delivering this performance in a lubricant. The issue is that the high levels of phosphorus in ZDDP can poison the catalytic converter and limit its efficiency. As a result, the API has had phosphorus limits in specifications for years, most recently reducing the limit to 0.08% maximum (there is no limit on the amount of Zinc) starting with the API SM category. This, however, does not mean that oils meeting the SN specification do not provide adequate engine protection. As specifications change, so do lubricant formulating approaches to maintain anti-wear performance. Pennzoil products that meet SN specifications are proven to deliver unsurpassed wear protection.

SN and SN PLUS are considered backward compatible to all earlier API categories, even the older categories that are considered obsolete.

The Pennzoil Platinum HTHS viscosities for both grades meet the minimum specification required. Much like the NOACK, the variability in results observed in this bench test minimizes the value of comparing results among different products in the same viscosity grade where the window is already quite narrow.

12. What are the NOACK values for Pennzoil Platinum 0W-20 and Pennzoil Platinum 0W-16?

Pennzoil doesn’t typically report NOACK values due to the inherent variability of the test. That said, Pennzoil products are formulated to have robust volatility characteristics.

0W-16 is not yet considered suitable for use in cars that don’t specifically recommend 0W-16 by the OEM. Carefully check your owner’s manual and use the recommended viscosity grade.

Those of us who build engines (less so as I get older …) can tighten things up to use 0W-16’s if they’ll survive serious thrashing. We know racers have been going to lighter oils, but the carnage has been high… We need serious AW capabilities since hydrodynamics will be even less available … Where recommended, 0W-16 products are required to meet the same specifications as a 0W-20, for wear. This is currently true for API SN and will also be a part of API SN PLUS and API SP.

Again, Pennzoil doesn’t typically report NOACK values due to the inherent variability of the test. That said, Pennzoil products are formulated to have robust volatility characteristics.

HTHS values are tightly controlled by the limits set for all viscosity requirements (there are many). Generally, this provides OEM’s with predictable oil film thickness properties at a myriad of temperatures and shear rates. Moving HTHS values too far, even within the specification, can cause one of the other viscosity requirements to fall out of specification. As such HTHS values are very consistent.

17. Will Pennzoil Platinum 0W-16 cost more?

Each market is different and competitive pricing is dependent on the market dynamics and the competitive landscape.

It is not a given that fuel dilution is higher with direct injection engines. In fact, improvements in direct injection engine designs are likely to reduce fuel dilution. However, the quest for lower viscosity oils, whether for direct injection engines or otherwise, is due to the challenge of providing improved fuel economy.

Lubricant formulating always requires careful balance between the characteristics of both the base oils and the additives. Part of formulating at the 0W-16 viscosity grade, of course, is done through management of the base oil viscosity. PurePlus base oils were specifically designed to deliver the required properties for 0W grade oils from the outset and help create a unique advantage for lubricant formulators at Pennzoil.

Formulating a 5W-16 is possible, but given that 0W-16 has better low temperature properties and is already in the market, we don’t foresee widespread recommendation of 5W-16’s by OEMs.

OEM’s have shown varying interest in these lower viscosity oils. Although no recommendations are yet made by OEM’s for this grade, Pennzoil will be ready when they are approved and ready for use. PurePlus base oils were designed with such considerations in mind.

Given the care it takes in engine design to use lower viscosity oils and the due diligence in recommending just the proper grade for maximum fuel economy and engine protection by the OEM, we don’t expect that lower viscosity oils (eg. 0W-12, 0W-8) will be allowed for use in engines that recommend 0W-20.

One strength of formulating with PurePlus base stocks is clearly observed in NOACK performance. Though this test is important to specifications, the NOACK is a laboratory bench test known for wider variability in test results relative to other bench tests. This variability in test results makes it more difficult to pinpoint the accuracy of a single result and minimizes the value of comparing results among different products.

24. Can I run it in my Toyota Corolla 2009 that requires 0W-20? Or in my Volvo XC60 Drive-E 2015?

Pennzoil always recommends you follow the viscosity grade recommended by the OEM in your owner’s manual or OEM service bulletin updating that recommendation.

Always follow the viscosity grade recommended by the OEM in your owner’s manual unless a service bulletin is issued by the OEM to update the recommendation.

It is always best to follow the recommended viscosity grade in your owners manual. Using a lower viscosity grade than was recommended puts the consumer at risk of wear issues in an engine that was not designed for it.

Not necessarily. Fuel economy is a global challenge being tackled by scientists all over the world, and of course auto manufacturers are a global business. As engine oil requirements can vary by region, often the formulating issues posed can be unique to a region, but equally challenging globally. That said, the demanding CAFE environment has pushed lower viscosity, improved fuel economy engine oils in the US where the same could also be said for European and Asian markets as well.

Certainly, as oils get thinner, concern about becoming “too thin” exists. However, there are strict limits on the requirements for oils to resist thinning, and the OEM’s are testing to make sure that their engines do not cause excessive dilution. Adequate safety factors exist to provide engine protection, which is still the primary function of the engine oil. Part of that equation is certainly the oil drain interval as it has been with oils of all viscosities.

29. Is there any extra special focus in the formulation of 0W-16 to ensure viscosity stability?

There is always focus on viscosity stability, and the same focus will be followed in formulating 0W-16 viscosity grades.

Whether it’s a newer 0W, or a more traditional viscosity grade, the same threshold for wear performance is in place for qualifying these oils using ASTM monitored, fired-engine testing. That holds true for the API SN Plus and API SP specifications that are on the way, where backwards serviceability to older categories has been included in development.

Not at this time. The blending approach in your question is often due to the belief that the reduction in Zinc dialkyldithiophosphate (ZDDP) use, required in modern formulating to prevent catalytic converter fouling, creates a wear issue in older vehicles. In fact, the limits that caused the drop in ZDDP have not changed since 2004. When they did, new, more effective ZDDPs were developed and launched to provide the wear protection needed in both modern and older engine technology. API specifications state that oils licensed under active categories may be used where earlier categories are recommended. Outside of ZDDP, however, the levels of additives used in oils hasn’t necessarily dropped. Lubricant technology constantly evolves to improve performance and enable the hardware technology employed by OEMS. It’s important to remember that, when mixing different lubricant products in an attempt to improve performance, there can be unintended consequences with harmful effects to your engine.

No, not at this time.

No, Pennzoil currently has several 0W-40 products that are available in the market, including Pennzoil Ultra Platinum as well as Pennzoil Platinum Euro. In fact, Pennzoil Ultra Platinum 0W-40 was recently featured in “Exorcising the Demon” and every Dodge Challenger SRT Demon that comes off the assembly line is factory filled with Pennzoil Ultra Platinum. The same goes for all Dodge SRT vehicles.

34. Any chance of getting the Pennzoil Platinum Euro 0W40 LL-01 approved?

We appreciate this question, please keep an eye on this space in the future.

No, not at this time.

No, not at this time.

The Shell Rotella line of heavy-duty diesel engine oils was just upgraded in 2016 to the latest heavy-duty diesel performance standard, API CK-4, and we introduced Rotella T5 ULTRA 10W-30, API FA-4. These upgrades were driven by the OEM need for improved performance in the areas of oxidation and fuel economy. Rotella T4 Triple Protection 15W-40 and Rotella T6 5W-40 Full Synthetic carry JASO MA/MA2 performance.
