The result, in the form of a\u00a0code (e.g., 18\/16\/13), indicates the number of contaminant particles in three size ranges. This is an effective tool for assessing the condition of the oil, filtration, and the level of environmental contamination or wear.<\/p>\n<p class=\"post__paragraph\">However, in engine oils, this method is meaningless \u2013 the large amount of naturally occurring soot and combustion products will certainly distort the result and produce high values regardless of the sample tested (e.g., 25\/23\/21). Therefore, in this case, the method for determining the content of solid particles according to PN-C-04178 is preferable. It allows for the determination of the percentage of solid contaminants in a\u00a0sample, regardless of their optical nature. High values may indicate, among other things, filter element inefficiency, possible incomplete fuel combustion, and the presence of degradation products. <\/p>\n<p class=\"post__paragraph\">Therefore, this parameter reflects, in a\u00a0sense, the degree of oil degradation and contamination. It can also indicate improper engine operation. Contaminants can increase the viscosity of the lubricating oil and lead to deposit formation. Furthermore, the heat transfer efficiency of the lubricating oil can deteriorate.<\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n\n<div style=\"height:45px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <p class=\"post__paragraph\">Choosing the appropriate method is not just a\u00a0matter of technique \u2013 it is the foundation of reliable diagnostics and system safety.

Due to its properties, it can ignite on contact with air, so it should be stored in paraffin oil or kerosene. Potassium is used in the production of fertilizers, glass, ceramics, and in the food and medical industries. Potassium also has very important biological significance and is discussed not only in the context of blood tests but also in the context of oil testing.<\/p>\n<p class=\"post__paragraph\">\ud83d\udc49 In oil diagnostics, potassium does not naturally occur in additives and should not be present in pure lubricants, with a\u00a0few exceptions. If it appears, it usually indicates contamination \u2013 most often from coolant, which may contain potassium. <\/p>\n<p class=\"post__paragraph\">\ud83d\udc49 An increase in its concentration in the oil may also indicate the presence of another fluid or residue from previously used lubricant. <\/p>\n<p class=\"post__paragraph\">\ud83d\udc49 The presence of potassium can also result from the ingress of environmental contaminants or hard water (containing potassium salts) into the oil. It\u2019s worth remembering that potassium itself isn\u2019t dangerous, but its presence can be the first sign of a\u00a0problem. <\/p>\n<p class=\"post__paragraph\">\ud83d\udc49 Therefore, in oil analysis, even a\u00a0trace of such an inconspicuous element can be significant \u2013 and it\u2019s worth taking a\u00a0closer look.<\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t
