Modern lubricants can only meet the exorbitantly increased demands of ever more efficient technology through the use of modern basic fluids and additives. The type and amount of additives to be used must be carefully tailored to the application as well as the base fluid. In addition, possible side effects of the additive use and interactions between the individual additive components are to be considered.

One problem that should not be underestimated here is the mixing of lubricating or hydraulic fluids. Even oils that are supposed to be "the same" in the light of the standards and specifications they claim can be additively modified and incompatible.

The seminar will give you an overview of the most important types of additives, their properties and applications and will deal with typical practical questions that are frequently asked about the use of lubricating oils and additives. In addition, practical examples are used to show which analysis methods are suitable for monitoring the additive state and how the analysis results are to be interpreted.
