AMSOIL Boosts CJ-4 Diesel Oil Offering
April 1st, 2009:
AMSOIL has reformulated its Premium API CJ-4 Synthetic 5W-40 Diesel Oil (DEO). In addition, AMSOIL now offers a new 15W-40 Premium API CJ-4 Synthetic Diesel Oil (DME). These exceptional diesel oils provide a level of protection afforded only by a truly high-quality synthetic oil - and do so over drain intervals of 3X OEM recommended drain intervals. They are the premium choice for API CJ-4 emission-compliant diesel oil required by model-year 2007 and newer diesel engines. Formulated for vehicles fitted with exhaust treatment devices, DEO and DME are also backwards compatible, offering maximum protection to all diesel applications.
New Drain Interval Recommendations
AMSOIL Premium CJ-4 Diesel Oils are recommended for extended drain intervals in engines that are unmodified and in good operating condition. In diesel applications, the recommended drain interval for AMSOIL Premium Diesel Oils is three times the original equipment manufacturers (OEM) recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals can be extended further with oil analysis. In gasoline applications, the recommended drain interval is two times the OEM recommendation, not to exceed 15,000 miles or one year, whichever comes first. In addition, normal and severe service are defined by the OEM, not AMSOIL. To determine the drain interval for a particular diesel application, refer to the owner's manual for the OEM's definitions of normal and severe service and multiply the OEM's corresponding drain interval recommendation by three for the recommended service interval for AMSOIL Premium API CJ-4 Diesel Oils. For example, if the OEM recommendation for normal service is 10,000 miles, AMSOIL Premium Diesel Oils would be recommended for 30,000 miles.
Premium Synthetic Formulation
AMSOIL Premium API CJ-4 Synthetic 5W-40 and 15W-40 Diesel Oils are engineered using the latest, highest-quality synthetic base oils and most advanced additive chemicals. Their heavy-duty detergent/dispersant additives and 10.4 TBN formulation control soot-thickening from exhaust gas recirculation (EGR) and blow-by to protect against corrosion and cylinder bore polishing (wear) and help prevent the formation of varnish/sludge deposits. AMSOIL Premium Diesel Oils are shear stable and provide exceptional oxidation stability to resist heat and breakdown in high temperatures. In addition, their low sulfated ash formulation promotes long diesel particulate filter (DPF) life.
Maximum Fuel Economy, Reduced Oil Consumption
AMSOIL Premium CJ-4 Diesel Oils have a very low high-temperature volatility rate (burn off). Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Additionally, lower volatility helps AMSOIL Synthetic CJ-4 Diesel Oils retain their viscosity after high-temperature service for continued dependable protection and excellent fuel economy. In fact, the Environmental Protection Agency's (EPA) Federal Test Procedure (FTP) confirms that AMSOIL 5W-40 Diesel Oil provides up to 3% better fuel economy than conventional 15W-40 diesel oils. Maximized fuel efficiency, extended drain intervals and reduced oil consumption add up to maximum value and minimal environmental impact.
Benefit All Diesel Engines
AMSOIL Premium API CJ-4 Synthetic 5W-40 and 15W-40 Diesel Oils are formulated with model-year 2007 and newer diesel engines fitted with exhaust treatment devices in mind, but are backwards compatible (Synthetic 15W-40 heavy Duty Diesel and Marine Motor Oil [AME] and Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil [HDD] remain available in the AMSOIL lineup). They are ideal for trucks with hydraulically-actuated electronically-controlled unit injectors (HEUI). HEUI fuel injection systems use a high-pressure oil pump which tends to shear down motor oil. AMSOIL Premium Diesel Oils, however, are formulated to resist heat and breakdown. They provide maximum shear stability in a wide variety of applications.
AMSOIL Premium CJ-4 Synthetic 5W-40 and 15W-40 Diesel Oils are recommended for diesel engines and where appropriate, gasoline engines required any of the following worldwide specifications:
API CJ-4, CI-4+, CF, SM
ACEA E7, E9
Mack EO-O Premium Plus
DDC Power Guard 93K218
Caterpillar ECF-3, ECF-2
MTU Type 1 & 11
Ideal Options for Fleets
AMSOIL Premium Synthetic Diesel Oils lower operating costs through improved fuel efficiency and extended drain intervals. They meet or exceed OEM specifications from a variety of manufacturers, allowing fleet operators to consolidate engine oil inventories in mixed fleets. In fact, the reformulated 5W-40 DEO meets and exceeds an expanded list of OEM specifications. In addition, AMSOIL Premium Synthetic Diesel Oils reduce downtime through extended drain intervals and improved equipment protection. AMSOIL CJ-4 Diesel Oils save money.
As additional consumers start buying newer, CJ-4 compliant vehicles, AMSIOL premium CJ-4 Synthetic 15W-40 Diesel Oil (DME) will provide a smooth transition from AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Motor Oil. AMSOIL premium Diesel Oils offer significantly extended oil drain intervals.
