The Use of Linear Sweep Voltammetry in Condition Monitoring of Diesel Engine Oil


One of the main ways to decrease engine oil changes is to increase drain intervals. Although it has been a controversial subject for years, increased drain intervals can be accomplished safely using lubricant analysis. Over the years, many diesel engine operators have effectively employed used oil analysis to extend engine oil drain intervals safely by monitoring the condition of the oil and the engine. Various tests have been used for the monitoring of engine oil. However, although it has been used for years to evaluate the remaining useful life of industrial lubricants, linear sweep voltammetry has not been used for routine monitoring of engine oil. This paper will show how linear sweep voltammetry can be an effective method for maximizing extended drain intervals in an over-the-road heavy-duty trucking fleet.
