Base Oil
Base oils are used to produce products such as lubricating greases, engine oil and metal processing fluids.We all know that different oils, including engine oil, hydraulic oil, etc., are all used for the lubrication of car parts and industrial machines. Base oil is present in all of these lubricants as a raw material.

Base Oil
Base oil is the oil used as a base additive in lubricants. People active in the production of chemicals know very well that base oil is the main additive in lubricants by volume. In terms of weight, on average, more than 95% of a lubricant's formulation consists of base oil.
Base oil is used in the production of automobile oils, diesel, industrial oil, grease, rubber materials, paraffin oil, white oil, etc.
It is interesting to know that in the production of some lubricants (such as hydraulic and compressor oil), 99% of the oil is base oil, and only 1% of them are made up of additives. Most base oils in the world are obtained from crude oil refining.
The main ingredients in the base oil are composed of these materials:
Naphthenic compounds
Paraffinic compounds
and aromatic compounds
How To Choice a Good Base Oil
Generally, the base oil is chosen according to our intended application. An essential criterion for the selection of base oil is its viscosity. High viscosity ensures film strength, and low viscosity ensures low temperature fluidity and lower energy consumption. In some cases, a balance between these two is chosen.
Of course, knowing the production method of base oil is not very necessary. What's important to know are the base oil options on the market along with their properties and pros and cons. If we choose the right and optimal lubricant, the chances of our device failure will be minimized. Synthetics are much more expensive than mineral oil, and of course, they minimize the possibility of machine failure. If you consider the cost factor a lot in your choice, try to make a wise choice.
