AMSOIL Boosts CJ-4 Diesel Oil Offering

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 (3 times) 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. For most AMSOIL motor oils, AMSOIL has defined normal and severe service and set mileage-based drain interval recommendations according to those parameters. The drain intervals of AMSOIL Premium CJ-4 Diesel Oils, however, are determined in a slightly different manner due to the wide range of drain interval recommendations. In diesel applications, the recommended drain interval for AMSOIL Premium Diesel Oils is three times (3X) the original equipment manufacturer’s (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 (2X) 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 formulation of varnish/sludge deposits. AMSOIL Premium Diesel Oils are shear stable and provide exceptional oxidation stability to resist hear 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 percent 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 for older diesel engines. 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.

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.

FULL WARRANTY

AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.

Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.

THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
