Lubricating oil is an important component of mechanical equipment operation. Its quality and performance directly affect the life and operating efficiency of the equipment. However, many people may find that the color of the oil has changed when storing lubricating oil, which often causes concerns: Has the lubricating oil gone bad? Can it still be used? Today, let's talk about the reasons for the color change of lubricating oil during storage and how to deal with it correctly.
Causes of lubricant color changes
l When lubricating oil is exposed to air for a long time, oxidation reaction may occur. Especially in high temperature or high humidity environment, oil is more likely to react chemically with oxygen in the air, causing the color of the oil to darken.
l If lubricating oil is not stored properly, it is easily contaminated by external impurities such as dust, moisture or other chemicals. If it is exposed to strong light or high temperature for a long time, the chemical structure of the oil may change, which will affect the color of the oil.
So, how should we deal with changes in lubricant color?
Lubricants should be stored in a cool, dry, well-ventilated environment and should not be exposed to direct sunlight or placed in places with excessively high temperatures. Even if the color changes, the lubricant does not necessarily become completely ineffective.
It is recommended to regularly test the viscosity, oxidation resistance and other properties of the oil to determine whether it can continue to be used.
Make sure the container is well sealed to prevent dust, moisture and other impurities from entering the oil. Clean the storage container regularly to prevent contamination.
