In the course of use, lubricating oil should be avoided in general, but the lubricating oil will encounter various conditions during use. Considering various factors, sometimes we have to replace it with new oil. In the case of oils being used, in this case we have to consider the problem of mixing oils. Under what circumstances can the lubricants be mixed? What should be paid attention to when mixing lubricants?

    1,The quality of similar products is basically similar, or high-quality oil mixed with low-quality oil is still used for the original equipment.

    2,need to adjust the viscosity of the oil and other physical and chemical properties, using the same oil with different grades mixed with each other, such as HL-32 and HL-68 hydraulic oil blended into 46.

    3,different types of oil, if you know that the two mixed oils are not added with additives, or one of them is no additives, or both oils add additives but do not react with each other, generally can also be mixed, just After mixing, the quality will be reduced for high quality oils.

   4,For oils that do not understand the performance, if it is really necessary to mix, it is required to be mixed before the mixing test (for example, if the two oils to be mixed are mixed in a 1:1 volume ratio and stirred uniformly), observe whether the mixed oil has odor or Abnormal phenomena such as precipitation, if odor or precipitate formation is found, it cannot be mixed. For qualified units, it is best to determine the main physical and chemical properties of the lubricating oil before and after mixing.

  5,Pay attention to the use of mixed oil.
