Cummins ISX Oil Recommendation
The following is a list of oils that are suggested for Cummins Isx. They also meet your engine’s requirements and are safe for your vehicle.ย
Shell Rotella T4 Triple Protection Conventional 15W-40ย
Mobil 15W-40 Delvac 1300 Super Motor Oil 15W-40
Delo 400 Conventional Diesel Engine Oil 15W-40
Shell Rotella T4 Triple Protection Conventional 15W-40ย
Shell Rotella T4 Triple Protection Conventional 15W-40 Diesel Engine Oil
Shell Rotella T4 Triple Protection Conventional oil is rated as one of the best oils available for the Cummins Isx engine. In terms of performance, this oil exceeds API CK-4 criteria. With the use of this lubricant, your engine will be able to run for an incredibly long time. Shell Rotella T4 conventional diesel oil greatly helps in the optimization of engine performance. This lubricant uses Triple Protection technology to protect the engine against deposits, wear, and oil breakdown.
Its cutting-edge additive technology is intended to improve deposit control. As well as, the engine cleanliness during the oil drain period. Wear control extends the life of moving metal engine surfaces by keeping them apart. This, together with enhanced protection against oil oxidation, enables a more efficient operation. Shell Rotella T4 Triple Protection is ideal for a huge number of heavy-duty engine applications. It’s built to withstand the most extreme engine conditions in new and old diesel engines.
Cummins Isx engine uses a special low-ash formulation that protects exhaust catalysts and diesel particle filters used in most recent low-emission vehicles. Furthermore, it protects against shear-induced viscosity loss.
Mobil 15W-40 Delvac 1300 Super Motor Oil
Mobil 112691 15W-40 Delvac 1300 Super Motor Oil
Mobil Delvac 1300 Super 15W-40 is a heavy-duty lubricant from Mobil designed to give your engine the best performance and durability. It was developed in partnership with some of the industry’s premier Original Equipment Manufacturers (OEMs). And therefore is highly sought after for a wide range of heavy-duty applications and conditions. The lubricant has an excellent soot and viscosity control.
Using this oil will also help reduce oil consumption. Mobil Delvac 1300 oil extends oil drain intervals (ODI) up to 1.5 times longer than the typical OEM ODI recommendation. If you want better protection, this is an ideal choice. Wear resistance is increased by up to 50% over what is required in API engine tests.. Plus it exhibits exceptional performance in current, high output, low emission engines. This oil also performs well in both on- and off-highway operations.
Among several noteworthy characteristics is its exceptional oxidation stability. Next is the ability to decrease both low and high-temperature sludge formation. Much like the other alternatives, the lubricant is totally backward-compatible with older conventional engines. This translates to great performance in both newer and older heavy-duty engines. As well as gasoline engines meeting API SN standards. Mobil Delvac 1300 Super also complies with the API SM criteria. In a nutshell, you’ll get better engine efficiency, longer engine life, and longer oil life.
Delo 400 Conventional Diesel Engine Oil 15W-40
Delo 400 SDE SAE Conventional Heavy Duty Diesel Engine Oil 15W-40
Delo 400 SDE SAE 15W-40 is distinguished by longer drain intervals, increased engine life, and improved protection. It is made using ISOSYN Advanced Technology to help extend the life of your critical diesel engine. This technology integrates Chevron’s best formulation with proprietary, high-performance additives. Dele 400 engine oil is designed for on- and off-highway applications.ย
An incredible feature of this product is its ability to reduce emissions from diesel vehicles. It ensures your engine produces as little diesel particulate matter as possible. Using premium grade oil, like Deleo, is the best method to avoid soot problems. Since it complies with the most demanding EGR soot control criteria and effectively disperses soot. This super-premium quality conventional engine oil delivers outstanding wear protection. So you can rest assured that your engine parts will function to their maximum potential because they will be adequately protected.ย
The oil surpasses the performance specifications set out by the industry and engine manufacturers. It’s also important to note that it’s backward compatible with prior API Oil Service Categories and engine types.ย
Cummins ISX Oil Type
Cummins API CF-4 approved oils can be used in Heavy-duty (L, M, N, ISX, and Signature) and High Horsepower (QSK and QST) engines. But the drain interval must be lowered to 15,000 kilometers [10,000 miles] or 250 hours. Cummins Inc. recommends the above engine oil specification for the Cummins ISX engine.
The primary recommendation from Cummins Inc. is to use 15W-40 multigrade for regular operation at temperatures above -15ยฐC [5ยฐF].
Multigrade oils provide superior engine protection at both low and high temperatures. They do this by retaining optimal viscosity across the engine’s operating temperature range. The use of this oil improves engine cranking in low temperatures. Additionally, multigrade oil decreases deposit accumulation and promotes engine durability by retaining lubrication in high temperatures.
It is critical to apply multigrade oils because they have been demonstrated to reduce oil usage by roughly 30% when compared to monograde oils. While 15W-40 is the ideal viscosity grade, in colder climates, lower viscosity multigrades can be used.

Final Words
To sum up, The Cummins ISX has a 14 U.S. Gallons (52.9 liters) oil capacity. The oil type recommended is 15W40 with API CF-4 certification.
Ultimately, your Cummins engine will perform well whether you use Shell Rotella T4 Triple Protection, Delo, or Mobil Delvac 1300 Super 15W40. The outcomes of using any of them are fantastic.
However, the Delo 400 SDE SAE 15W-40 oil recommendation is a solid choice for you.
