如果比标准空压机油中气泡上升速度快，说明这种油的粘度偏低。
If air pressure than the standard oil bubble rising fast, explain this oil viscosity is low.
定量地考察不同粘度级别和质量等级的发动机油的低温动力粘度，可以为SAEJ300- 99(2001)标准在中国的执行和生产多级油提供的数据平台。
The investigation on low temperature viscosity of engine oils with different degrees of viscosity and quality can support for the implementation and production of SAEJ300-99 (2001) standard in China.
试验结果表明，油样的大多数质量指标都在规定的换油周期内，只有粘度超过了国家换油标准。
The results of bench evaluation indicate that the most quality targets are in the range of national standard for oil drain except viscosity.
