[0019] [Example 1]
[0020] According to the parts by weight in Table 1, weigh 30 grams of calcium petroleum sulfonate, 10 grams of octyl diphenylamine, 10 grams of barium dinonyl naphthalene sulfonate and 50 grams of base oil, and heat and stir at 50-60°C 1 hour to completely uniform. See Table 1 for details.
[0021] Weigh 1.5% by weight and 2% by weight of the diesel engine oil composition of the present invention, add them to the new diesel engine oil product or the newly prepared diesel engine oil components, heat and stir uniformly to prepare test oil for use.
[0022] To evaluate the effect of the diesel engine oil composition of the present invention, the method is as follows: Measure 100 ml of test oil in a 100 ml conical tube, place the conical tube in an oven at 60-105°C, stand for 168 hours, take it out and observe Record the appearance of the oil layer and the formation of deposits. It is better that there is no change in oil layer definition and no precipitation. Th...
