PC-11 User LanguageDraft Description for API CK-4
5.X.X.X CK-4—For 2017 Heavy-Duty Diesel Engine ServiceAPI Service Category CK-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines. These oils are formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, the use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust aftertreatmentsystem durability and/or oil drain interval.
These oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. API CK-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot related viscosity increase.
Engine oils that meet the API Service Category CK-4 designation have been tested in accordance with the ACC Code of Practice and may use the API Base Oil Interchangeability Guidelines and the API Guidelines for SAE Viscosity-Grade Read Across.
API CK-4 oils exceed the performance criteria of API CJ-4,CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations.
Marketers may license products meeting API CK-4 requirements as API CJ-4, CI-4 PLUS, CI-4, and CH-4.

PC-11 User LanguageDraft Description for API FA-4
5.X.X.X FA-4—For 2017 Heavy-Duty Diesel Engine ServiceAPI Service Category FA-4 describes certain XW-30 oils specifically formulated for use in select high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway greenhouse gas (GHG) emission standards. These oils are formulated for use in on-highway applications with diesel fuel sulfur content up to 15 ppm (0.0015% by weight). Refer to individual engine manufacturer recommendations regarding compatibility with API FA-4 oils.
These oils are blended to a high temperature high shear (HTHS) viscosity range of 2.9cP-3.2cP to assist in reducing GHG emissions. These oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. API FA-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot related viscosity increase.
Engine oils that meet the API Service Category FA-4 designation have been tested in accordance with the ACC Code of Practice and may use the API Base Oil Interchangeability Guidelines and the API Guidelines for SAE Viscosity-Grade Read Across.
API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 PLUS, CI-4, and CH-4 oils. Refer to engine manufacturer recommendations to determine if API FA-4 oils are suitable for use. API FA-4 oils are not recommended for use with fuels having greater than 15 ppm sulfur. For fuels with sulfur contents greater the 15 ppm, refer to engine manufacturer recommendations.
June 21st , 2011 the EMA/TMA made a request of the DEOAP for a new Heavy-Duty Diesel Engine Oil Performance Standard.
Drivers for the new category included:
U.S. Environmental Protection Agency (EPA) is in process of adopting regulations which will mandate improvements in fuel efficiency from heavy-duty on-highway diesel engines and vehicles, beginning in 2014 with additional efficiency improvements beginning in 2017 (the GHG Rule.).
Engine lubricant performance can have a significant influence on an engines’ ability to achieve EPA’s GHG emissions goals.
Anticipated test obsolescence
EMA/TMA requests that the PC-11 category be split into two separate and distinct subcategories with corresponding HTHS performance levels: One that preserves historical heavy-
duty oil criteria One that provides fuel efficiency
benefits.
Improvements or changes in performance, relative to API CJ-4 Oils included: Oxidation stability Aeration benefits Shear stability Scuffing/Adhesive wear control Compatibility with biodiesel blends
Note: Supporting data was provided for the performance improvements requested
Three Phase Process Phase 1: Category Request/Evaluation
NCET Established (June 2011-December 2011)
Phase 2: Category Development NCDT Established (December 2011-December 2015)
Phase 3: Category Implementation DEOAP (December 2015- December 2016)
Consensus Process with Major Stakeholder all included:
API Oil Marketers EMA Representative (On-and Off- Hwy) ACC Representative Engine Tests Labs Trade associations including ASTM, SAE, etc.
Open meetings to allow all interested parties to participate.
Performance Challenges How is shear stability to be evaluated? What oxidation test will be used? Need to better define biodiesel compatibility What should the HTHS be for the lower viscosity/fuel economy specification?
Development Challenges Very aggressive time line required to meet first license date target Multiple new tests to be developed Precision / BOI / VGRA matrix costs likely to be very high Potential resource limitations due to overlap with GF-6
Marketing Challenges How are we to market this? What is the plan for educating the consumer education? What will the new category be called?
A. Support the request for the new category and recommend to DEOAP that the request be forwarded to the API Lubricants Committee for consideration to proceed with category development. This recommendation shall identify the need for the category, recognize its feasibility, provide a timetable for category development, suggest draft language for the category, and identify the proposed method for funding development of the new category. The API Co-Chairperson of the DEOAP shall present the DEOAP recommendation, along with appropriate documentation, to the API Lubricants Committee for consideration at its next meeting.
B. Deny the request, explaining to the sponsor in writing the reasons for the denial. The sponsor has the option of resubmitting the request with additional information.
C. Not reach consensus. If the NCET cannot reach consensus on the request for a new performance category, the API Co-Chairperson shall provide the API Lubricants Committee with the vote outcome and a summary of the reasons for the action.
The NCET’s specific charge is to evaluate the request and to make one of the decisions below:

Taskforce on Oxidation/Nitration recommends Volvo T-13 for oxidation. Taskforce on Aeration recommends Caterpillar Oil Aeration Test Shear Stability Taskforce recommends more severe limits on current 90 cycle
shear test for xW-40 grades (except for 0W-40) Biodiesel taskforce concluded no available test and no need to include a test at
this time. No scuffing/adhesive wear test. Development of this test continues. Sufficient
data not available soon enough to support inclusion in this category.
BOI/VGRA group recommends precision matrix based on available funding from funding group
Recommended category naming nomenclature and structure to API LG

Development of ASTM B ballot – Issued Nov. 2, 2015
NCDT is in Agreement After the ASTM Vote all of its original goals and objectives have been met The team will forward all procedures, facts, data, and information that is
pertinent to the new category to the DEOAP The DEOAP and NCDT meet to ensure that the tests developed under NCDT
guidance satisfy the need expressed by the original sponsor
When the DEOAP and NCDT Meet: Ensure that the tests developed under NCDT guidance satisfy the need
expressed by the original sponsor Performance targets contained in the proposed consumer language are met by
the tests proposed for the category Timetable is acceptable Test methods chosen to define the new standard represent the most cost-
effective means of establishing the new performance level. API BOI/VGRA Guidelines are evaluated and being established DEOAP Co-Chairpersons, complete a Category Development Package and with
a recommendation for formal approval, to the API Lubricants Group API Lubricants Group Approves the complete package including the final
consumer language
For the ASTM Functional Group Review the appropriateness of the test data developed for
discrimination and precision. Agree on the final description for each new performance test and
that the optimum test methods and performance limits have been chosen.
At least one “demonstration” reference oil capable of meeting all minimum performance criteria is required.
For the ACC functional group, Ensure that the ACC Code of Practice includes each of the new
engine performance tests
From SAE and other cooperating agencies Any standards, codes, and publications that are necessary parts of
the new category.
