Abstract : Crankcase oil additive concentrates, designed for use as an oil supplement oriented towards consumer or after market applications, were investigated in an attempt to define their overall performance effectiveness. Physiochemical data was generated on the eighteen oil concentrates to assist in understanding the mechanism of their reported activity. Their effectiveness, relative to dispersancy and detergency, was defined by developed laboratory techniques. The data subsequently generated revealed that many of the oil concentrates offered very marginal improvement in dispersancy and detergency whereas many created potential performance problems as a result of high foaming tendencies and increases in low temperature fluidity properties.
