How to check water content in engine oil?

Some users find that the engine oil is opaque or opaque in the use of engine oil, they think that the engine oil contains water, and the engine oil moisture content qualification standard is less than 0.03%. If it exceeds this standard, it will be harmful to the engine oil when it reaches 0.1. The following are commonly used on-site inspection methods:

1. Visual inspection The engine oil contains water, which will appear cloudy or opaque. After shaking, it will produce more bubble rice.After adding the engine to run, it will appear milky white or a lot of foam.

2. Heat in test tube at 80-100℃.
