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
Features and Benefits
Mobil Delvac Extreme is formulated with synthetic basestocks and a boosted additive system tailored to deliver extended performance for up to two times beyond OEM recommended oil drain intervals1. The proprietary formulation delivers excellent wear protection, exceptional oxidation stability2, and outstanding TBN retention. Mobil Delvac Extreme also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.
Mobil Delvac Extreme 10W-30 has the potential to improve fuel economy2.
