The Mobil Delvac 1300 Super 10W-30 from ExxonMobil is a synthetic blend diesel engine oil designed for both on- and off-highway applications, including trucking, mining, construction, and agricultural industries. The formulation provides extended oil drain intervals, 50% more wear protection than required in API engine tests, oxidation stability, and soot and viscosity control. The engine oil is also fully backward compatible and can work in both newer and older heavy-duty engines, and meets or exceeds the requirements of API CK-4, CJ-4, CI-4 PLUS, CI-4 and CH-4 service categories.
