Mobil Delvac 1300 Super 15W-40 is a high-performance premium synthetic blend diesel engine oil that helps to extend engine life for diesel vehicles and equipment used in on and off-highway applications. 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. This engine oil helps to deliver extended performance for up to 50% beyond OEM-recommended oil drain intervals.* Mobil Delvac 1300 Super 15W-40 is a fully backward-compatible oil that works to deliver excellent soot and viscosity control. Mobil Delvac 1300 Super diesel engine oil has outstanding resistance to oil consumption as well as resistance to corrosive and abrasive wear. For nearly a century, Mobil Delvac is the diesel engine oil of choice for the world's leading heavy-duty original equipment manufacturers (OEMs)** and helps protect your engine to keep you going strong on the road. Formulated to meet or exceed the requirements of API CH-4, CI-4, CI-4 PLUS, CJ-4, CK-4, SN, JASO DH-2-17, ACEA E7, ACEA E9, Caterpillar ECF-3, Cummins CES 20086, and Isuzu DEO (with DPD Equipped Vehicles). Approved by the following OEMs: Deutz DQC II-10 LA, Detroit Fluids Specification 93K218, Detroit Fluids Specification 93K222, Mack EOS-4.5, Mack EO-O Premium Plus, MB-Approval 228.31, Renault Trucks RLD-3, MAN M 3575, MAN M 3275-1, Volvo VDS-4, Volvo VDS-4.5. (*Results may vary based on vehicle/engine condition, driving, and environmental conditions. Consult OEM or ExxonMobil before implementing extended ODIs. **Compared to a SAE 15W-40 conventional engine oil. Savings are dependent on vehicle engine type, outside temperature, driving conditions, and your current engine oil viscosity.)

Q: Why doesn’t 1300 meet Ford’s specifications for their PowerStroke diesel engines? It would not be that difficult for Delvac to increase the ZDDP/Phosporus levels to meet Ford’s requirements

Mobil vs Shell

9 months ago
I worked for a Shell Distributor for 33 years and have always been partial to Shell T4 1540, however when Shell went to has to liquid technology customers started to have issue with oil pressure and consumption. When I left the oil company I switched to Mobil and notice my equipment carried better oil pressure and no consumption. There for I feel Mobil oil has better technology.

Yes, I recommend this product.

Preferred over any other brand

Use in my semi for years. Prefer Mobil to be used in my heavy trucks as well as my personal cars. Mobil is cleaner oil and my semi use to leak using Rotella oil. When started to use Mobil Delvac I have no issues of leaking or nor have to add to oil between oil changes.

Yes, I recommend this product.

Over 20 years and I've never had an oiling failure

a year ago
I've been using this for 20 years since working as a semi mechanic. We used Delo, Rotella and Delvac. The dealer advised 10,000 mile oil changes, but we had a fleet that ran Delvac to 30,000. Every oil change had an oil sample done and every one came back over 50% remaining. I've never seen anything else come close. I currently use this in all my vehicles and equipment (large car, small car, mini truck, mini van, lawn tractor, lawn mower, chinese mini excavator, rototiller, generator and snowblower) and I will continue to do so until I have a problem. The jug/bucket I buy clearly states this is SP rated even though the website doesn't say it is. The 10w-30 is harder to find, but worth it for colder temps.

Yes, I recommend this product.
