Tier 4 Final Engine Information

Diesel Fuels EPA Tier 4 engines require a new, higher level of fuel quality for reliable operation. This new level of quality can be a new experience for users. Older engines may have tolerated fuels with contamination, water, or incorrect specifications without long-term, negative consequences. However, use of fuels with this same low quality in new EPA Tier 4 engines can result in increased maintenance costs, reduced efficiency, and possible permanent damage. WARNING: • Use only Ultra-Low Sulfur Diesel (ULSD) fuel. ULSD fuels must contain 15 ppm or less sulfur content. Use of high sulfur content fuels will damage fuel and exhaust aftertreatment systems. • High Pressure Fuel Rails in new Tier 4 engines require a new level of fuel cleanliness. Internal engine components can be damaged by particles as small as 5 microns. High quality fuel filtration and clean fuel must be a priority. • EPA Tier 4 engine systems include fuel/water separation filters to ensure quality fuel without the presence of water. These filters must be properly maintained to be effective. Excessive water in fuel will cause permanent engine damage. What precautions can I take to ensure fuel quality? • Regularly check bulk fuel storage to ensure usage of quality fuels. Periodic testing by independent labs is recommended. • Use only reputable providers of quality fuel. • Follow all guidelines in the vehicle Maintenance Manual and engine manufacturer’s service information for regular servicing instructions of fuel and filtration systems. • Never ignore warning information or fault codes given by the engine ECM through the Taylor Integrated Control System (TICS) Is there a certain type of DEF that must be used? • DEF purchased for use in Tier 4 Final engines should state certification of the American Petroleum Institute (API), German Institute of Standardization DIN70700, and the International Organization for Standardization ISO 22241-1, and meet AUS – 32 specifications. This will ensure the proper purity and concentration (32.5%) of urea. Engine Lubricating Oils & Coolant • CJ-4 (low ash) specification is the recommended oil. CJ-4 is the American Petroleum Institute (API) lube oil specification for engines using exhaust aftertreatment such as a Diesel Particulate Filter (DPF) and cooled Exhaust Gas Recirculation (EGR). Commonly known as “low ash” oil, it is more resistant to heat and leaves lower amounts of ash deposits. • CI-4 specification is permitted. • Refer to your particular vehicle’s Maintenance Manual or Engine Operator Guide for current lubricating oil specifications. These specifications can vary from specifications on existing engines. • Ethylene Glycol Antifreeze (Low Silicate) (GM 6038--M or ASTM D3306 & D 6210) WARNING: • The use of any fluids, in TIER 4 Final engines, other than those specified may result in engine damage and could effect emissions and result in fines by the E.P.A.
