C280 marine engines for use in U.S. flagged vessels and vessels operating in U.S. inland waterways must meet the Environmental Protection Agency (EPA) emission standards set forth in "40 CFR Part 1042 Control of Emissions from New and In-Use Marine Compression-Ignition Engines and Vessels". New C280 engines that are greater than 2000 bkW must meet EPA Tier 4 emission standards starting in 2014. These standards are referred to as EPA Marine Tier 4 in this Special Publication.Emission control for the C280 marine engines for EPA Marine Tier 4 includes improved combustion systems and aftertreatment starting in 2014. The aftertreatment is a Selective Catalytic Reduction system (SCR). In the SCR system, Diesel Exhaust Fluid (DEF) is injected in controlled amounts into the engine exhaust stream. This process is necessary to reduce NOx in the presence of the SCR catalyst. DEF is available in many brands, including those brands that carry the AdBlue or API certification. DEF is also generically referred to as urea. The SCR system is also effective in reducing certain hydrocarbon and particulate emissions.Some C280 marine engines for use outside of the United States are also equipped with SCR aftertreatment systems. Complete engine system which includes engine and SCR systems are subject to the International Maritime Organization MARPOL Annex VI regulations are included.Additives used in lubricating oils can negatively affect the performance of the SCR aftertreatment system. Engine oils for use in C280 engines equipped with SCR aftertreatment systems must have the following chemical limits:
0.12 percent maximum phosphorous
2 percent maximum sulfated ash
0.4 percent maximum sulfurTable 1 lists the oils that meet the required chemical limits and are recommended for C280 engines with SCR aftertreatment oils.

Viscosity Grade Specification Requirements
Cat DEO, mono grade SAE 40 API CF(3)
Cat DEO-ULS, multigrade SAE 15W-40 API CJ-4
Commercial lubricants SAE 15W-40 Field Performance Evaluation and API CJ-4/Cat ECF-3/ACEA E9

(1) Oils listed in this table must have the chemical limits listed in this section of this Special Publication.
(2) Caterpillar engine oils are the preferred oils. Commercial oils as a group are second choice oils.
(3) Oils that fulfill all the API CF requirements.Note: Oils that do not meet the chemical limits in this section of the Special Publication are not allowed for use in engines that are equipped with SCR aftertreatment systems. Follow the recommendations given in Table 1 above.Commercial oils meeting Cat ECF-3, API CJ-4, and ACEA E9 specifications also meet the required chemical limits for engines that are equipped with SCR aftertreatment system. ACEA E9 oils are validated
