Global Mining Review,

ExxonMobil is introducing Mobil SHC™ Elite a breakthrough synthetic gear and bearing circulating oil for the mining industry. The lubricant’s advanced formulation can help protect mining equipment operating at extreme hot and cold temperatures, while increasing energy efficiency and extending oil drain intervals.

Extensive testing shows that Mobil SHC Elite can deliver double the oil life1 of traditional synthetic products and up to 12 times2 the oil life of mineral products. It can also help protect equipment operating at temperatures up to 150°C in intermittent service, meaning it is ideally suited for use in a range of mining equipment, such as in the gears and bearings of excavators, haul trucks, augers and conveyors.

The advanced synthetic lubricant is specifically formulated to deliver excellent wear protection and oxidation resistance without any of the compatibility challenges often associated with glycol-based products used in high temperature applications.

In addition, Mobil SHC Elite has also demonstrated an enhanced torque ratio, enabling it to deliver a 3.6%3 energy efficiency improvement when compared with conventional mineral oils.

“Demanding loads and tough conditions mean that every component of mining equipment must be optimised and protected from extreme in-service temperatures,” said Emre Noyan, industrial marketing manager at ExxonMobil. “Mobil SHC Elite’s extended oil life, wide temperature range performance and energy efficiency improvement can help operators increase uptime and cut costs – giving them a competitive edge.”

Mobil SHC Elite has already received approval for its proven performance from leading gearbox manufacturers including Siemens, whose FLENDER gear units depend on effective lubrication to ensure reliability in intense operating environments.


1. Up to double the oil life as demonstrated in numerous bench and rig tests. Oil life will vary based on application and operating conditions.

2. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used.

3. Energy efficiency relates solely to the performance of Mobil SHC Elite when compared to conventional (mineral) reference oils of the same viscosity grade in gear applications. The technology used allows up to 3.6% efficiency compared to the reference when tested in a worm gearbox under controlled conditions. Efficiency improvements will vary based on operating conditions and application.
