对以上实施例1～5船用柴油机油组合物进行性能测试。采用曲轴箱模拟试验(SH/T0300)评价油品的清净分散性；采用氧化诱导期测定法(压力差示扫描量热法)(SH/T0719)评价油品的氧化安定性；采用船用油水分离性测定法(SH/T 0619)评价油品的水分离性；采用液相锈蚀(GB/T 11143B法)评价油品的防锈性。其中，实施例1～5船用柴油机油组合物性能测试结果记载在表3中，对比例1～5的性能测试结果记载在表4中。
对以上实施例1～5和对比例6～8船用柴油机油组合物进行储存稳定性测试。将组合物置于100mL离心管，室温储存18个月，观察油品外观并记录沉淀量，评价油品的储存稳定性。储存稳定性测试结果记载在表5中。
表3实施例1至实施例5的检测结果
