Shell recommends the Tellus S range of oils for pumps containing silver-plated components. Laboratory tests show that oils utilising zinc technology vary considerably in terms of their effects on silver. Early ZDDP technology was incompatible with silver but recent Tellus formulations are not aggressive to this material except in the very severe applications where temperatures could be high.
