What does the color of grease relate to?

Several factors affecting the color of fat are follows: (here refers to the unused new fat color)

1. Color of the base oil. Different crude oil origin, different refining techniques will cause the color of the base oil difference. The color of the base oil is not a quality indicator, but usually, the base oil contains less impurities and their color is lighter. For example, the recent launch of the market of Mobil fast bully oil, it belongs to this situation. 
2. Color of the additives. According to the lubrication protection needs of different equipment, such as gasoline engine, diesel engine, gearbox, industrial hydraulic system and so on, different lubricating oil should add different additives to achieve the best lubrication protection effect. For example, the engine oil has: viscosity index improvement agent, antioxidant, cleaning dispersant, anti-foam agent, anti-rust agent, anti-wear agent, anti-emulsifier and so on. All of these additives have their different colors. When we continue to innovate or adjust the additive formula to maintain our technological leadership, the color of the lubricating oil will change differently, or deeper, or lighter, can not be generalized. Take Mobil One, which we recently launched on the market, because we switched to an additive formula for this formula, anti-emulsifier, etc. All of these additives have their different colors. As we continue to innovate or adjust the additive formula from the. Holding our technology leading advantage, reflected in, the oil color will have different changes, or deeper, or lighter, can not be generalized. Take the Mobil One, which we recently launched on the market, as we switched to a new technology additive formula that is characterized by darker colors, so you may find the Mobil One darker than before. In fact, it's even better than ever before. Please rest assured to use it.
3. The color of the special dyes Perhaps most friends do not know, sometimes to add a certain stain to change their original color. The purpose is sometimes to serve as a warning to distinguish other lubricants, sometimes to distinguish different product lines, the dyeing agent will not have any lubrication protection effect. Take our automatic gear oil " for example, we dye it red to remind our users not to add it to the engine or gear box; we stain the third stroke engine green to cause engine damage; we dye the Mobil fat MP green and the Mobil fat XHP blue, basically to distinguish the two different product lines. To sum up, it is possible to judge the deeper or lighter color changes of lubricants and grease simply from their internal quality changes.
4. Common colors and their meanings: White or transparent: usually general-purpose or multi-purpose lubrication Lipid, suitable for general industrial applications. Yellow: Sometimes a high temperature or high pressure grease that can work under extreme conditions. Red: commonly used in high temperature, heavy load, or high-speed applications, with Good adhesion and corrosion resistance. Blue: Generally used for special applications, such as food grade or specific industrial equipment.
