A heat-tube oxidation apparatus and the method of using it to evaluate the detergency of the CC grade engine oil are presented in this paper. The evaluation results of heattube oxidation tests at optimum test conditions for the detergency of CC grade engine oil cor- relate well with the WTD value of 1-H2 engine test. This method is fast, economical, simple and convenient to use, requiring small amount of oil samples with good repeatability. It has a good prospect for extensive use.
