Advanced technological requirements

Lubricant production and science go hand in hand. Through various basic components and advanced blends, products with unique properties are created, for instance when it comes to lubricating at different temperatures. At the same time, modern oils are often closely integrated with the engineering they lubricate.

The field of science in question is called tribology and is the study of lubrication, abrasion, and friction. We produce the right lubricating oil for the right technology and as needs vary so much, there is a wide range of products: everything from the engine, hydraulic and turbine oils to special products for wind power, forestry and agriculture, metalworking and the manufacturing industry. All with their own more or less unique blend.


At our lubricant production plant in Nynäshamn outside Stockholm, we work with around 750 products, and oils for vehicles and industry are the two largest areas. The work essentially revolves around the art of blending lubricating oils. All the raw materials are delivered ready to use to the plant, where they are blended to create the right oil.

Whatever application the oil will be used in, there are several common denominators for almost all lubricants, namely that the oil should cool, seal, keep clean and protect against rust. Another important aspect is how friction is affected. The aim of engine oil is usually to achieve low friction with adequate lubrication. This affects the blend that gives the oil its specific properties. Technology requirements have also become more advanced over the years and determine how an oil must be formulated to do its job.


A good example is an automotive industry, where emission requirements have increased dramatically. And when the conditions for vehicle manufacturers and their technologies change, the lubricating oils have to be adapted accordingly. Apart from lower emissions, the requirements also concern lower fuel consumption and longer replacement intervals, so the oil has to be able to function for longer than before.

Lubricating oils have always been important, but they have become even more important as demands on vehicle and machine manufacturers have increased. You could say that the oil has become an increasingly integrated part of the various applications that need lubricating. Developments are going the same way in the industry too. As tools and machines become more advanced, the oil specifications have to be increasingly specialized.


Most lubricating oils are based on a few fundamental components. The first is the base oil, which comprises 60–90% of a typical lubricating oil. There are several classes of base oil, both mineral and synthetic oils, and the product achieves its basic performance properties via the right mix. The base oil affects the end product’s volatility and stability, but also its minimum flow properties, internal friction and how well it protects against corrosion. Synthetic base oil affords us broader options and enables us to customize the product in more ways.

The next ingredient is the viscosity modifier. This influences the oil’s thickness and is designed to reduce its change in viscosity, even if the temperatures vary. And they do vary, a lot. Some engine oils need to withstand temperatures of between -40 and +350 degrees Celsius, while still retaining their lubricating properties.

And last but not least, various additives are blended into the oil. This is when it gains its final properties. The additives function as cleaners contain antioxidants that affect the service life and enable the oil to cope with friction and counteract abrasion more efficiently. In engine oils, the cleaning properties are particularly important. For industrial oils, it is particularly important for the additives to extend the service life of the oil and prevent seizure under high load.


Most of the ingredients mixed into a lubricating oil are liquid. The volume of a blend tends to vary between 1 and 40 cubic meters, and the blending process itself takes between 12 and 48 hours.

For each lubricating oil, there is a recipe that specifies quantities, the order in which the ingredients are added, how long it should take and how high the temperature must be. Lubricating oil may contain anything from 2 to 22 ingredients. The blending order is important to avoid negative chemical reactions between ingredients. Certain additives must be added when the temperature is high, and others when it is lower.
