In our last article we focused on the question of whether oil analysis was still relevant today? While this is an age-old process, the benefits of oil analysis still continue to live on today although the methods involved have significantly evolved since its inception. In this article, we will do a deeper dive into the traditional methods of oil analysis versus some of the new cutting-edge technologies which exist today and whether we may see a replacement of one method over the other or a union moving forward.
If you’ve ever performed an oil analysis you know that this process follows certain standards which are listed in the report. These standards govern the world of oil analysis and form the basis of how these tests are executed. There are committees dedicated to revising these standards to ensure that they are still relevant to the applications of today, one such committee falls under the ASTM body (American Society for testing and Materials).
Equipment has changed over time where oil sumps have become smaller but now produce more power. Oils are under more stress as they are expected to perform at higher temperatures under elevated environmental conditions and still protect the equipment. Global oil manufacturers work together with OEMs (Original Equipment Manufacturers) to ensure that the oils developed can work with their components in these increasingly harsher conditions. But what constitutes an oil “working properly”?
This is where oil analysis / sample testing plays a crucial role. Oil analysis tests have been standardized through authorized committees to ensure that the same test can be performed in different parts of the globe using the same procedures. This ensures that there can be a fair comparison of the results of these tests across the globe. These tests should also be repeatable (or get the same results every time they are performed).
Typically, these tests are usually carried out in a laboratory environment, using state of the art equipment to achieve / maintain the required standards. However, sample taking, sample shipping and other human factors often result in misleading and / or extremely delayed reporting of the results. This is where emergent technology can alleviate some of these challenges.
