Kendall Super-D XA (exhaust advantage) is a premium quality, synthetic blend, API CJ-4 engine oil developed for use in four-stroke cycle diesel engines compliant with the U.S. EPA's 2007 on-highway exhaust emissions standards. It is specially formulated to protect exhaust aftertreatment devices such as diesel particulate filters (DPF) and diesel oxidation catalysts (DOC). It also is recommended for use in pre-2007 on- and off-highway diesel equipment with either EGR or conventional diesel engines, and for mixed fleets with diesel and gasoline-fueled vehicles. Super-D XA is formulated with a blend of synthetic and high-quality Group II base stocks and a proprietary low-SAPS additive package to provide outstanding engine protection in new and older diesel engines. It is fortified with Kendall's exclusive Liquid Titanium additive technology for enhanced oxidation resistance and protection against wear. This additive enhancement provides increased engine protection from a strongly bonded titanium shield formed on the surface of critical engine parts, which reduces wear and helps extend component life. Super-D XA has excellent soot dispersancy to protect against abrasive wear and soot-induced oil thickening, and to ensure good low-temperature pumpability even with highly soot-laden oil. It provides excellent bearing corrosion protection and protects against sludge and varnish formation. The synthetic blend formulation provides enhanced thermal stability at high temperatures and improved low-temperature properties compared with conventional diesel engine oils. Super-D XA meets or exceeds the performance requirements of API Service Categories CJ-4 and SM, and all major OEM heavy-duty engine oil specifications for 2007 and later on-highway diesel engines.
Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance.
This oil has a weight of SAE 15W-40, meaning it has an SAE viscosity rating of 15 in cold temperatures and a rating of 40 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle.
Full Synthetic Oil
This oil is a full synthetic oil, meaning crude oil is not used in making it. Synthetic oil can be used in vehicle engines instead of motor oils refined from crude oil, and often provides superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil.
