PT KJS wanted to maximise engine oil performance in its vessels by increasing the engines’ oil-drain interval without compromising on oil performance and overall equipment protection.
Distributor PT CSB, with support and guidance from Shell Marine, proposed that PT KJS should run a trial using Shell Rimula R4 X 15W-40 heavy-duty engine oil.
The trial showed that the oil-drain interval could be doubled, from 500 to 1,000 hours, by using Shell Rimula R4 X 15W-40 without compromising engine protection.
As a result of changing to Shell Rimula R4 X 15W-40, PT KJS has reported potential annual savings of about US$4,9001 per vessel through the longer oil-drain interval and consequent lower oil consumption. PT KJS is set to save an estimated US$107,8003 a year across 22 vessels.

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.
