Mobil SHC™ 524 synthetic hydraulic oil helps increase oil drain intervals by 700%

Achieved oil drain interval of

32,000 hours
Mobil SHC™ 524 synthetic hydraulic oil


An Italian steel mill has operated bridge cranes under extremely severe environmental conditions with temperatures up to 120° Celsius. The hydraulic systems on its cranes were originally lubricated with hydraulic oil that degraded rapidly, forming deposits and oil sludge, which caused 2-3 unscheduled production outages annually. The oil drain intervals were around 4,000 hours.


To optimize oil drain intervals and decrease oil deposit and sludge formation, ExxonMobil recommended Mobil SHC™ 524 synthetic hydraulic oil, with excellent high temperature performance and oxidation resistance. Mobil ServSM Lubricant Analysis was used to monitor oil condition and ensure a safe increase of oil drain intervals.


The company reports that switching to Mobil SHC™ 524 synthetic hydraulic oil increased oil drain intervals of the bridge cranes safely from 4,000 to 32,000 hours compared to the previous mineral oil.


Planned maintenance was decreased helping customer to reduce employee interaction with equipment and diminish associated injury risks.

Environmental Care

Reduction in oil consumption has helped steel mill to decrease waste oil generated for disposal.

“*This proof of performance is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used.
