About this item

Product details

Mobil Delvac 1300 Super 15W-40 (4-pack / 1-gallon bottles) is a synthetic-blend diesel engine oil designed to ensure extended engine life. Delvac diesel oil is ideal for business operations that require reliable transport on a daily basis.

Mobil Delvac 1300 Super is developed in collaboration with top OEMs (original equipment manufacturers) and is recommended for a wide range of heavy-duty applications like the trucking, mining, construction, agricultural and marine industries.

What Can I Expect From Mobil Delvac 1300 Super 15W-40 oil?

Delvac oil provides excellent soot and viscosity control as well as resistance to oil consumption and corrosive wear. It meets all API CK-4 requirements put in place by Detroit, Cummins and Volvo. It also offers up to one and a half the average recommendation for extended oil drain interval potential. This oil also meets all CI-4 PLUS and CH-4 requirements as well as typical manufacturer requirements.

Mobil Delvac 15W40's Many Uses

Mobil Delvac 15W40 synthetic oil can be used in even the most modern diesel engines, even those equipped with EGR and after treatment systems. It also is ideal for older diesel designs, so you don't need other oil for your different rigs. Heavy-duty trucking applications like agriculture, mining and construction are no match to the Mobil Delvac 15W40 formulation. It's designed to offer low-temperature pump-ability, which presents as reduced wear during start-up and a faster flow of oil.

How Long Will Mobil Delvac 1300 Super 15W-40 Case Last?

This case of Delvac diesel oil comes with four bottles, each of which contains a full gallon of oil. As it works for mixed fleet operations, you can use it in all diesel engines in your fleet without worries. With a case of four, the oil is an economical option that you can store until needed. Rather than dealing with quart bottles, it makes for a convenient oil choice that is easy to use. The superior oil consumption level leads to lower costs when using large amounts of oil.

I have used Delvac exclusively in my DD15 for its entire life. 888,000 miles and counting. With NO rebuild! Changed at 25k give or take with 1 gallon of Lucas also included. Never had a bad oil sample report.
