Oil analysis

In the same way as a blood test can give a good picture of your health, an oil analysis can provide invaluable information about the status of machines and engines.

With analyses of used lubricants, you can undertake preventive maintenance, optimize production and lower maintenance costs in a simple and cost-effective way. Effective monitoring of the condition of the oil can give you an early warning before a breakdown happens and can even provide clues as to where the problem is located.

We are more than willing to help you determine which analysis you require. Regardless of which of our oil analysis services you use, you receive invaluable information that increases reliability. If you have any questions please contact us at: fuchs@fuchs-oil.fi or +358 20 7459 660.

Contamination of oil

Lubricating oil in machines and lubrication systems risks being contaminated by small metal particles, water, fuel or other things that should not actually be there. The risk factors affect the oil in various ways and can cause its properties to change and the function deteriorate. It is called contamination of the oil.

High temperature and certain substances cause the oil to oxidize. Oxidation causes the oil to age prematurely and causes it to lose its lubricating properties and to form resins and deposits. They form a sticky surface that eventually causes valves and moving parts of the machine to fall and fast.

Particles in the oil
Particles are small impurities from the machine and environment that can lead to wear and tear. Research has shown that the particles bind other contaminants and accelerate oxidation in the oil. In order for people to avoid particles, the oil needs to be filtered. Through careful filtering, the life of both oil and machine equipment can increase significantly.

Fuel in the oil
The fact that petrol or diesel goes into engine oils and other lubricating oils is not uncommon. This may be because the fuel system leaks so that fuel can enter the oil. It affects oil properties, for example, so that viscosity changes and oil lubricates worse which leads to efficiency losses. Fuel contaminated oil must be replaced if the level is above 2.5%.

Water in the oil
The fact that there is water in the oil is quite common in, for example, hydraulic systems on forest machines. Here too, the properties of the oil are affected, which can cause it to oxidize and that engines and machines begin to corrode from within. Water in the oil can also lead to increased friction and wear. It can also cause hydrolysis, which breaks down the oil. In the case of water contaminated oil, the water must be separated or the oil replaced. Different types of oil tolerate different amounts of water.
