Why can't air compressor oil be replaced with ordinary oil?

Air compressor oil cannot be replaced by ordinary oil, which is mainly due to the significant differences between air compressor oil and ordinary oil in many key aspects. Here are the specific reasons:

1. Use Differences

• air compressor oil: Specially designed for air compressors, mainly used to lubricate and cool moving parts such as cylinders and pistons, and work in harsh environments such as high temperature, high pressure, and high humidity.
• Ordinary oil (e. g. motor oil): It is mainly designed for the internal design of the engine, which plays the role of lubrication, cooling, sealing, cleaning, etc., but its working environment and requirements are different from those of the air compressor.

2. composition and characteristic difference

• air compressor oil: Composed of base oil and additives, additives pay more attention to anti-oxidation, anti-emulsification, anti-foam and other characteristics to adapt to the working environment of the air compressor. It has good oxidation resistance, wear resistance, corrosion resistance, adhesion, fluidity and low volatility.
• Ordinary oil: Although it also contains base oil and additives, its additive formula and characteristics are not fully adapted to the working environment of the air compressor. For example, engine oil may lose its performance at high temperatures, while air compressor oil can maintain a stable lubrication effect at high temperatures.

3. viscosity grade difference

• air compressor oil: The viscosity grade is usually lower to reduce the resistance of compressed air.
• Ordinary oil (e. g. motor oil): There are many choices of viscosity grades, which are selected according to the working environment and use requirements of the engine.

4. work environment and requirements differences

• air Compressor: The working environment is even worse, often facing high temperature, high pressure, high humidity and other conditions. Therefore, air compressor oil needs to have higher performance requirements, such as excellent high temperature oxidation stability, low carbon deposition tendency, suitable viscosity and viscosity temperature performance.
• Ordinary oil: Although it also has certain lubrication and cooling performance, it usually cannot meet the special needs of air compressors in harsh working environments.

5. equipment life and performance

• use of air compressor oil: It can ensure the normal operation of the air compressor and extend its service life, while keeping the air pressure system clean and stable.
• Use of ordinary oil: It may cause equipment performance damage, increased wear and tear, frequent failures, and may even cause safety accidents.

In summary, due to the significant differences between air compressor oil and ordinary oil in terms of use, composition, viscosity grade, working environment and requirements, ordinary oil cannot replace air compressor oil. In the selection of lubricating oil, according to the working environment and requirements of the equipment, select the appropriate special oil.
