Mobil SHC™ 630 gear oil success story

Annual savings of

Extruder gearbox gear oil lubricant analysis


Honam Petrochemical Corporation produces Linear Low Density Polyethylene (LLDPE) and operates two large 4.2 MW extruders with Kobe Steel, Ltd. gearboxes running three shifts a day, seven days a week. Lubricated with a competitive mineral ISO VG 220 gear oil, the extruder gearboxes run on rigorous production schedules. Honam asked Mobil engineers to identify a gear lubricant to increase gearbox reliability and extend the oil drain interval.


Mobil engineers recommended transitioning to Mobil SHC™ 630. Formulated with high viscosity synthetic base fluids and a proprietary additive system, Mobil SHC™ 630 gear oil is designed to provide outstanding performance in extreme service applications. Mobil also recommended implementing routine Mobil Serv℠ Lubricant Analysis to monitor the condition of the extruder components and in-service lubricant.


Since the transition to Mobil SHC™ 630 synthetic gear oil, the extruder gearboxes have been running smoothly and power consumption is down by 4.8 per cent. The performance benefits delivered by Mobil SHC™ 630 have resulted in a US $60,000 annual savings for the plant.

*This success story 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.
