What additives are needed and in what quantities? And finally, the indicators that need to be achieved, such as its viscosity, pour point, flash point, etc. Thank you all
The formulas are kept secret. Hehe, it is said that nowadays additive companies can develop formulas based on your base oil.
Lubricant formulation involves base oils and various functional additives, and compatibility must also be taken into account; as a result, there is no single, fixed formula used by all manufacturers, and continuous adjustment and optimization are necessary. Therefore, it is recommended that you understand the properties of base oils and the standard specifications for specific lubricants, and then select additives for blending tests. Books on lubricants contain some standard formulas that can be used as a basis. Initially, composite agents can be used, as they are relatively simple, but they are costly; in the future, single-agent formulations can be gradually adopted to reduce costs.
Thank you to the two people above; it’s been educational
If it is a metal processing oil, you can contact me
Your requirements are quite simple, and it seems there isn’t much that can meet them! After all, the formulas are usually kept confidential. In fact, even for oils of the same grade, the proportions of various components in their composition can vary!
Confidential information cannot be given to you; it’s like something that is the property of others. However, there is plenty of general information available – you just need to search for it. There are many types of lubricants, but they are all based on common ingredients, and much of the knowledge related to them comes from experience.
What kind of information are you looking for? I can help you find it

Regarding additives, if you have advanced technologies of your own, you can first prepare a compound by mixing individual agents together and then combine it with the base oil. If you find it troublesome, you can simply mix a compound with base oil, but such a mixture doesn’t offer much differentiation from the oils used by competitors; as long as their price is lower than yours, your product will have no advantage. It can be made using base oil + compound + single agent (which serves a reinforcing function). However, since the base oil or additives already contain sulfur and phosphorus compounds, a single-component product should be chosen that is free from such compounds; otherwise, the level of sulfur and phosphorus in the formulation will exceed the allowed limits. For example, calcium borate, organic molybdenum, boron ceramics, lanthanum borate, etc., are all single agents that do not contain sulfur or phosphorus; moreover, these single agents can be selected accordingly to meet the various needs of customers. Calcium borate and organic molybdenum both possess excellent extreme pressure and anti-wear properties (as evidenced by the effect of hanging weights). Boron ceramics offer both extreme pressure and anti-wear benefits as well as a repair function. Lanthanum borate not only has good anti-wear properties but also exhibits excellent cleaning effects; it can adsorb onto metal surfaces to form a protective layer that prevents carbon deposits from adhering to the inner walls of the engine.
