Caterpillar DEO-ULS 15W-40 CJ-4

Cat DEO-ULS is the highest quality diesel engine oil for Caterpillar on- and off-highway engines equipped with aftertreatment systems (On-Highway 2007/2010 and Off-Highway Tier 4, Stage IIIB/IV, Step 4), as well as, diesel engines without aftertreatment and automotive gasoline engines. Cat DEO-ULS exceeds the performance requirements of Caterpillar ECF-3 (Engine Crankcase Fluid Specification) and the API CJ-4 and API SM categories.

Cat DEO-ULS is formulated with precise amounts of sulfated ash, phosphorous, and sulfur to maintain the life of aftertreatment system components while providing superior engine protection. In extensive testing, Cat DEO-ULS had an oil consumption rate more than three times better than ECF-3 standards. Cat DEO-ULS was also demonstrated to deliver excellent valve train protection and to minimize the formation of piston deposits.
