With good reasons the producers of this type of engine recommend a Drain Oil analysis. Only frequent tests provide users with an accurate measure of the wear conditions within the cylinder. Not only is the Base Number of the Drain Oil important but also the iron content. The iron particles in the oil correspond with abrasive wear. Whereas Fe2+ and Fe3+ compounds show the amount of cold corrosion. Despite all that, the engine producers make no On Board Test Set available. However, several On Board Test Sets exist on the free market. It’s an advantage that these Test Sets only take a few minutes to provide a result of abrasive wear and cold corrosion. A laboratory will hand out the results after a few days or weeks after the sampling due to the shipment of the oil. Some of the On Board Sets only give the total iron content. And there are additional differences between the available test Sets. These differences affect mainly the handling, the cost, the accuracy and the analysis method itself. This list of differences also displays the common disadvantages and problems every operator has to handle with. Even though all these problems are common knowledge to ship owners and operators, no comparison or dissertation can be found. Furthermore a standardization of On Board Test Sets is not in sight. This paper gives a general view of the basic analysis methods and a selection of On Board Test Sets. It is important to outline a first comparison of these products and their methods. Additionally this paper sketches a possible future solution.
