A) An oil analysis provides information on the condition of oil and changes in it
 

The most important aspect of an oil analysis is well-performed, regular sampling

The timing of sampling determines how reliable and informative the analysis is. The sample must always be taken from the same location, and in similar, clean conditions with properly rinsed tools. In a high-quality system, the sampling location is marked.

‘For example, if the oil sample is taken from a valve at the bottom of a gearbox, the sample will be contaminated because any impurities in the system find their way to the bottom. Occasionally, oil samples are taken outdoors in rain where water can enter the oil sample. This results in a contaminated sample, even though the oil is clean,’ says Kari Saukkonen from KSA OIL CARE. KSA OIL CARE is Masino’s long-term partner in the field of oil analysis, maintenance and oil changes, and the maintenance of oil systems.   

Companies generally have good knowledge of their own systems and the location of sampling points, enabling them to carry out sampling themselves. When necessary, Masino can perform sampling for you, either separately or in conjunction with a visit scheduled for another purpose. 

Oil analyses focus on trends

A single analysis offers information on the condition of the oil at the time of sampling. For basic analyses, certain standards have been defined for quality factors, such as water content and purity levels. However, no definitive conclusions can be drawn from the results of an individual analysis. Instead, the focus should be on comparisons with previous tests carried out in similar conditions. 

‘We should perform regular analyses and study the results to identify trends that indicate what changes are taking place in oil quality. On the basis of such results, we can draw accurate conclusions and plan appropriate measures,’ explains Saukkonen. 

B) In terms of maintenance needs, no two oil systems are the same

No one-size-fits-all solutions exist

No two oil systems are the same. This means that there is no one-size-fits-all solution for solving problems. While the analyses provide information on the current situation and trends, further investigation into the cause of the problems and more thorough examinations of the system are required for a decision on appropriate measures.  

‘An experienced maintenance professional can offer experience and tips learned from other systems, but there is no single solution that suits all situations,’ explains Saukkonen.

An oil change is not always required 

The choice of a correct maintenance solution is important, not only for the functioning of the system but also for cost reasons.
‘I’ve come across cases where an oil analysis indicates the need for an oil change, but a closer look revealed that adding an antioxidant was enough to fix the problem. This worked out about 50% cheaper than an oil change,’ says Saukkonen. 

When the root cause of the problem is identified and rectified, it may well turn out that oil that has been in use for ten years can be used for another ten.  

The assessment of maintenance needs should not focus solely on oil

The assessment of oil maintenance needs is typically based on the oil analysis, which is used as a tool for selecting the correct measures. Oil maintenance should cover the assessment and maintenance of the system as a whole. 

In the choice of measures, a distinction must be made between signs of problems in oil quality and indications of impurities originating from the system. If the assessment reveals that the pipes contain impurities, the situation is discussed with the customer to decide what can and should be done.

‘Sometimes you need to consider factors outside the system. If the exhaust air surrounding the device is of low quality, impurities may enter the machine that way,’ explains Saukkonen. 

C) High-quality, timely oil maintenance measures support the system 

Clean oil benefits the system as a whole

Oil is a consumable and its lubrication properties may deteriorate over time. The removal of impurities helps prolong oil’s service life. Ensuring that the oil remains clear of impurities helps keep the entire system in good condition.

‘Studies show that using clean oil helps prolong the service life of ball bearings,’ explains Saukkonen. 

Avoiding unnecessary maintenance helps cut costs

Occasionally, the recommended measure is a new analysis on an agreed schedule. 

‘Sometimes a customer has scheduled downtime and would like to have oil maintenance carried out at the same time. However, there is a possibility that the assessment of the need for maintenance indicates that no measures are required,’ says Saukkonen. 

High-quality results with a meticulous attitude and open communications 

The cornerstones of high-quality oil maintenance include a meticulous attitude towards basic work and open communications. While performing maintenance on a customer’s worksite, we always keep the customer up to date with progress and provide information on any unexpected issues immediately. With the customer’s permission, we take pictures of the problem sites and deliver a comprehensive report on the measures taken to the customer after completing the work. 

‘I’d really like to stress the significance of collaboration with the customer. Customers generally know their devices well, and collaboration produces the best solutions for different situations and problems,’ emphasises Saukkonen. 

Masino supplies a wide range of oil management devices and services to meet customers’ needs and specifications. We offer all the necessary equipment for hire, or alternatively you can order comprehensive services on a turnkey basis. Our technical expertise and professional experience covers all industrial maintenance and repair operations.
