Cummins engine oils: properties, viscosity, replacement schedule

Cummins engines fully correspond to our drivers’ idea of the quality of automotive equipment.

There comes a time when the driver definitely wonders what kind of oil to put into a Cummins engine. In the more than rich range of lubricants for these engines, G-Profi MSI Plus 15W-40 oil is considered the best option, and Premium Blue Engine Oil lubricant, as a result of tests, was named the official lubricant for Cummins engines.

According to experts, these brands of oils have the following advantages:

due to their increased cleaning properties, these oils constantly clean all parts of the engine, extending its service life;
they perfectly lubricate parts on which the necessary oil film always remains, protecting the motor from abrasion, both in normal modes and under overload conditions;
these lubricants have higher dispersing capabilities, which prevent an increase in oil viscosity and wear of parts even in the presence of burning;
they have significant neutralizing capabilities that can enhance resistance to corrosion and oxidation;
They have powerful anti-friction properties that enhance engine power.

In addition, the following lubricants are acceptable for Cummins engines:

Lubri-Loy® 15w40 API CJ-4/SN;
Cummins CES 20078, 20076;
Lubri-Loy® API CI-4/SL Multi-Grade Diesel Motor Oils;
Cummins CES 20081;
Cummins CES 20072, 20071.

In different countries of the world, the company's research groups are actively working to develop the most optimal types of oils for Cummins diesel engines. Their tests are included in special worldwide classifiers, for example, API. Owners of cars with Cummins engines can only enjoy the fruits of their labor.

Requirements for the properties of engine oils for Cummins

In order for a car engine to last longer without losing its power and other technical characteristics, the driver must provide it with high-quality oil. A good oil filter is also mandatory for this system. In addition, compliance with the technologically prescribed frequency of oil and filter changes plays an important role.

High-quality engine oil does not allow dry friction of engine parts in contact during movement, and, accordingly, failure of parts, breakage of belts and wear of tensioner bearings. In addition, the presence of oil reduces the friction force to a minimum level, if, of course, sufficient tightness of the cylinders is ensured.

By the way, the heat displayed on the instrument panel is not the actual engine temperature. The devices only indicate the degree of heating of the coolant. When the engine is running, their temperature is more or less stable and is usually 90°C. But the temperature of lubricants is less constant and can reach 140 ° C, which depends on the speed of the car.

New models of Cummins fuel filters have the following advantages: ease of dismantling and installation, the highest level of fuel purification, long filter service life and no need for manual pumping.

Externally, the thermostat is a glass or metal vessel, which is protected by thermal insulation from the environment. There are many types of classification of this device, which you can find out about here.

For this reason, developers set the most appropriate level of oil characteristics for each specific engine. If these parameters are observed, a high efficiency is ensured, and engine parts, under standard conditions of use, receive effective protection from unnecessary wear.

The level of oil quality characteristics for a B-C series engine corresponding to average power ratings, according to generally accepted standards of the American Petroleum Institute, must meet the properties of the following classes:

CG-4/SH;
CF-4/SG;
CH-4/SJ.

European standards (ACEA) prescribe types of oils belonging to classes E-2, 3 and 5.

If you focus on these categories of oil, this can provide decent conditions for the operation of any Cummins engine.

An important characteristic of motor oils is their viscosity. This parameter is important in the sense that at higher levels the oil will adhere better to the surface of the working parts of the engine. But it must also maintain its fluidity.

It would seem that there is nothing complicated about this. However, it is the viscosity of the lubricant that is most subject to change under the influence of ambient temperature. Therefore, this indicator cannot be called constant; rather, it is variable.

SAE - American Association of Automotive Engineers - presented its own very practical classification of motor oils depending on viscosity. It gives the permissible viscosity of the oil at the temperatures it reaches while the engine is running. This classification also shows the temperatures of the engine operating in safe mode. The brand of oil must correspond to the specific engine.

But many car owners believe that the optimal oil is all-season, citing its economic benefits. This lubricant allows engine operation at any temperature.

SAE 15W-40 grease can be considered a universal oil. It is acceptable at most typical air temperatures in our latitudes. But if the winter is too cold, you will need oil with a suitable viscosity.

So, in the temperature range from -10 to +40 oC, an all-season tire is suitable. If the thermometer drops below -25°, then you need winter oil 10W-30, and in frosts above -40°C you need arctic lubricant 5W-30.

Replacement of kamens gaskets is mandatory in case of wear or significant overheating. The reason for the replacement may also be a leak of coolant or oil, as well as a breakthrough of exhaust gases.

Repair and upgrading of Cummins diesel engines is simplified due to two factors: the availability of spare parts and the electronic engine diagnostic system. You can learn more about engines and spare parts from the cummins catalog described in this article.

Low-viscosity lubricants such as 10W-30 and, especially, 5W-30 are used only where there is a very frosty winter, and the air temperature drops below -50°C. They make engine starting softer and easier, remaining quite fluid, despite such harsh conditions.

However, when the engine is constantly running on low-viscosity oils, its service life is significantly reduced due to increased abrasion of parts.

Cummins engines tolerate problems with lubricant viscosity very patiently. It is noteworthy that even for break-in they do not require special oils. Moreover, the developers recommend using the same oil that is used during normal driving.

Oil change schedule for Cummins engines

The engine cannot constantly operate on lubricant alone. Adding a portion of new oil does not help the situation either. Typically, the lubricant is replaced when the car reaches the mileage specified in the vehicle instructions.

However, the frequency of this operation can be influenced by a fairly large number of factors. Therefore, engine oil for Cummins must be changed taking into account:

car use mode;
conditions of use of the car;
fuel quality.

The procedure for determining the regularity of lubricant changes in the engine is logical and simple:

read the manufacturer's instructions regarding service oil changes;
assess the presence of factors that, in addition to mileage, shorten the interval in the frequency of oil changes;
monitor the level and quality of lubricant in the engine.

As they say, “if you don’t oil it up, it won’t work.” And if he does go, it won’t be very far. This proverb was invented long before the invention of the Cummins engine, but quite briefly and succinctly characterizes its dependence on the quality and condition of the oil.
