Abstract:

In the introduction of the paper, the requirements encountered in modern machines and hydraulic equipment will be stated. The mutual impact between machine requirements, lubricant quality and specifications will be shown.
Following, premium quality hydraulic oil on mineral basis and its main characteristics will be presented. Its main properties and advantages over conventional hydraulic oils will be mentioned. These advantages make it possible to reduce maintenance and production costs despite the higher price of oil. The first results of practical testing of this oil in some Slovenian companies will be presented.
