What is the acid value? What does it mean for production?

Acid value is the number of milligrams of potassium hydroxide that is needed to neutralize the acidic substances in 1 gram of oil sample. 

There are many additives in the finished lubricant products, and some additives are acidic and some are alkaline, so to test the acid value of the oil should be before the additive adding. 

To measure the acid value of the oil before the additive, can know the basic degree of refinement. To measure the acid value of the oil in use can know the quality changes of oil, as a parameter to replace the new oil.

The acid value is too large, indicating that the oil oxidation is serious, should consider to change the oil.
