The sustainability dimension Performance and sustainability are increasingly aligned rather than competing priorities. Extended drain intervals can reduce the volume of oil produced, transported, and disposed of per operating year. Efficiency gains help lower energy-related emissions. Optimised additive chemistry can achieve required performance at efficient treat rates, reducing the embedded carbon footprint per litre of finished lubricant.


Practical implications for formulators and end users


For lubricant formulators, modern industrial gear oil (IGO) additive packages can span multiple viscosity grades and base oil types with a single core chemistry, simplifying inventory and quality assurance. Advances in viscosity modifiers enable Group III-based synthetics to deliver performance closer to PAO-based formulations.


For end users, evaluation often considers total cost of ownership. Improvements in reliability and service life can deliver significant value by reducing interruptions and maintenance activities. Extending drain intervals from annual to multi-year cycles enables reduced oil consumption as well as the labour, downtime, and waste disposal associated with oil changes and unplanned shutdowns.


Conclusion It is growing increasingly evident that industrial gear oils must now deliver on multiple fronts simultaneously: robust wear protection, stable foam and air-release behaviour, extended service life, energy efficiency and materials compatibility. The combination of synthetic base stocks and advanced additive chemistry has demonstrated that these objectives need not be trade-offs. Evidence from field trials suggests that these technologies can deliver reliability, efficiency, and sustainability benefits in demanding industrial applications. For operations counting the cost of every minute of downtime and every kilowatt-hour of consumption, this represents an important development in industrial lubrication practices.
