Mobil Delvac™ Extreme 15W-40
Synthetic diesel engine oil
Fully backward compatible, Mobil Delvac Extreme 15W-40 engine oil delivers exceptional performance in both newer and older heavy-duty engines. Its boosted formulation provides:
• Exceptional oxidation stability*
• Extended oil drain interval (ODI) potential up to 2X the average OEM ODI recommendation†
• 46 percent more antioxidant and 44 percent more anti-wear additive than Mobil Delvac™ 1300 Super
• Excellent soot and viscosity control
Mobil Delvac Extreme 15W-40 engine oil delivers updated high-temperature performance under the extreme operating environments found in the trucking, mining, construction and agricultural industries. Accordingly, this oil meets or exceeds the requirements of API CK-4, CJ-4, CI-4 PLUS, CI-4 and CH-4 service categories, as well as key original equipment manufacturer (OEM) requirements.
Mobil Delvac Extreme 15W-40 diesel engine oil is recommended by ExxonMobil for use in:
• Modern, high-performance diesel engines with exhaust gas recirculation (EGR), after treatment systems with diesel particulate filters (DPFs) and diesel oxidation catalysts (DOCs)
• Naturally aspirated and turbocharged, diesel-powered engines
• On-highway light- and heavy-duty trucking, including mixed fleets
• Off-highway industries, including mining, construction, quarrying and agriculture
