In recent years there has been an increasing focus on reducing costs, also including cylinder lube oil consumption.
This can be achieved in many ways.
You can upgrade cylinder lubricators and injection valves, or you can use scrape down analyses, visual port inspections etc.
However, it is clear that no matter which lubrication solution you are in possession of, it is a fundamental condition that the users of the systems are well educated, in order to use the full potential of the equipment.
