How long does a gear lubricant typically last before needing replacement?

The primary operating factors influencing the life of a lubricant are temperature, load levels and contamination. Periodic oil analysis – such as that provided by Mobil Serv℠ Lubricant Analysis – will provide the necessary trend information for comparison to the used oil parameter limits that will help determine when to replace the oil.

Mobil™ lubricants, and in particular Mobil SHC™ lubricants, have the demonstrated capability to perform beyond 30,000 hours in continuously operating systems where the above operating factors are well managed.
