“…So it is very important to check that these additives will not deteriorate the properties of the oil in this regard. The flash point is another parameter investigated because the influence of these additives on the acid number, base number and vis-cosity of the engine oil [12][13][14] was previously investigated. These studies show that it is worth conducting research in this direction, with better results improving the properties of the oil obtained for effective microorganisms than for nanosilver.…”

The article presents the effect of the effective microorganisms and silver compounds addition on the flash point of new and used oil. The work describes environmentally friendly additives to engine oil. Next the ignition point of the engine oil were described. In the further part, the research stand and methodology were presented. In the main part of the article the flash point values for new and used oil compared to oils with the effective microorganisms and silver compounds addition were shown. New and used oil samples were mixed with effective microorganisms in the form of a liquid (2.5 ml and 5 ml) and ceramic tubes (3 pcs. and 6 pcs.). In addition, silver solution and silver compounds were mixed in the same amounts as the liquid effective microorganisms. In summary it was stated, that adding of the effective microorganisms to the fresh oil in liquid form causes the flash point to drop significantly. It follows that effective microorganisms in liquid form have a very negative effect on the properties of the oil. In the case of microorganisms in the form of ceramic tubes, which in this larger amount slightly increase this point compared to oil without additives. Regardless of the type of silver and its quantity, very low flash point values were obtained. For used oil the best results are obtained with the addition of microorganisms in liquid form. For the used oil the addition of silver compounds does not have the beneficial effect of restoring the original properties.

This paper presents research upon the impact of ecological measures on the water content of new and used oil. Water and microorganisms are major factors of contamination for engine oils and fuels, and they lead to a significant reduction in the lifetime and performance of engines. The microorganisms occur naturally in the environment, from which they enter into the oil and fuel. Despite various preventive measures, it is not possible to completely remove water from petrochemical products. That is why the protection against and prevention of the various types of contamination of petroleum products, especially microbiological contamination, is very important. Biocides are one example of the agents used for the prevention of contamination; biocides belong to a group of pesticides that are used to eliminate microbial contamination. Due to the fact that currently available methods are ineffective and often have a detrimental effect on the natural environment, research is underway to discover modern and ecological measures to combat the phenomenon of the microbiological contamination of petroleum products. This paper shows the effects of environmentally friendly additives on the water content in lubricating oil, i.e., whether these additives cause the release of water bound in the oil, and whether their composition increases the water content of the oil. Samples of new and used oil were utilized for the tests. Effective microorganisms (EM), in both liquid form and within ceramic tubes, were added to the new and used oil samples. In addition, silver solution and silver compounds were added in the same amounts as the liquid effective microorganisms. In order to confirm and compare the obtained test results, the dynamic viscosity, flash point, acid number, base number, and water content were measured, and these are presented in this study. These measurements were followed by the analysis of the influence of the additives on the water content. It was found that the adding of effective microorganisms to fresh oil in liquid form caused a significant increase in the water content of the oil; in the case of a smaller amount (2.5 mL), the water content more than doubled, and in the case of a larger amount, the water content exceeded the measuring range of the device. Next, an evaluation of the impact of these environmental measures on the water content was carried out. It was found that the adding of liquid effective microorganisms to new oil caused a significant increase in the water content of the oil; the water content more than doubled for the addition of 2.5 mL, while for a larger addition (5 mL), the water content exceeded the measuring range of the device. The same was true for the addition of silver compounds, regardless of their type and amount. The best results were obtained with ceramic effective microorganisms, but the results for silver cannot be presented due to the over-titration of the device (the amount of water exceeded the measuring range). For used oil, the liquid effective microorganism was found to give the best result.
