Miscibility of Base Oils and Thickeners
Caution must always be taken when mixing different lubricants. On the one hand, lubricating oils and the base oils and thickeners used in greases may be incompatible (refer to tables 1 and 2). On the other hand, the effect of additives and the performance capability of lubricant mixtures cannot be estimated without the appropriate tests being carried out.
If technical conditions make it impossible to avoid lubricants becoming mixed, the risk that should be expected in terms of reduced performance and lubricant incompatibility can at least be estimated using the tables. In such cases, expert advice from lubricant experts is generally recommended – from the Lubricant Technology department at Schaeffler Technologies AG & Co. KG, for example.
