Italian Power Company Extends Oil Life and Streamlines Maintenance Schedules

A result that shows the value in upgrading lubrication practices

Italian power company Asja Ambiente Italia SpA was operating a series of Jenbacher J420GS engines 24 hours a day and with an oil drain interval (ODI) of 1000 hours. It wanted to trial a new lubrication package to extend its ODI and reduce maintenance time.


The Shell Lubricant Solutions team ran a test on one engine to demonstrate the advantages of Shell Mysella S5 S 40, using Shell LubeAnalyst to monitor the condition of the oil inside the engine.
After the successful test, this solution was rolled out across the plant, to extend the ODI and synchronise it with scheduled maintenance. This not only aimed to reduce oil consumption, but importantly, to boost equipment uptime.


Switching to the new package of products and services:

  • extended the ODI from 1,000 to 2,500 hours
  • streamlined the plant's maintenance schedule, with liner and piston life increasing from 20,000 to 30,000 hours.

The reduced spend on consumables and maintenance has seen the company reporting estimated annual savings of US$33,000.

The savings indicated are specific to the calculation date and mentioned site. These calculations may vary from site to site and from time to time, depending on, for example, the application, the operating conditions, the current products being used, the condition of the equipment and the maintenance practices
