What is diesel engine oil?

Diesel engines must be well-lubricated to avoid untimely wear and tear of moving parts. To achieve this, lubricants are added with the end result of the engine lasting longer while saving you money in replacement costs.

To make the most of lubricating a diesel engine, it’s imperative to follow lubrication management best practices in order to keep your hardware running costs low, and to ensure your oils perform optimally.  Ordering in bulk means being able to replenish low oil levels without needing to source more oil.

Types of diesel engine oil

All engine oils are split into two main types defined by their base oil: synthetic oils and mineral oils. Of these, there are several subtypes that split into viscosity grades, and also different.

Within these two base oil types, engine oils are separated into different grades – or oil viscosities – which refer to what environment the engine oil is designed to be used in.

Specifically, the numbers in the engine oil grade refer to the minimum and normal operating temperatures of the engine. The minimum is followed by a W for winter, informing us of the temperature the oil remains fluid in winter.

For instance, 15W40 engine oil is designed to run in 40℃ temperature, but in cold environments can run at 15℃.

Engine oils also must meet specifications of the ACEA (European Automobile Manufacturers ‘ Association – or Association des Constructeurs Européens d’Automobiles), which includes a letter to refer to the oil’s class and a number which refers to the category in that class.

As an example, E9 engine oil refers to use for heavy-duty diesel engines, with 9 being one of four classes (4, 6, 7 and 9) that take into account oil drain performance and Sulphated Ash, Phosphorus, and Sulphur (SAPS) levels.
