Frequently Asked Questions
What are some common misconceptions about lubricant usage?
The oil level should ideally be maintained between the upper and lower markings on the dipstick. If there’s too much oil, it can leak into the combustion chamber through the clearance between the cylinder and the piston, where it will burn and form carbon deposits. These carbon deposits will accelerate wear on the cylinder and piston and speed up oil contamination.

What are the possible reasons for the oil warning light to come on?
The oil warning light typically comes on due to insufficient oil pressure in the lubrication system. Common causes include the following: ⑴ The oil level in the oil pan is too low; check whether there are any leaks caused by poor sealing. ⑵ The engine oil has been diluted by fuel, or the engine is operating under excessive load at excessively high temperatures, causing the oil’s viscosity to decrease.
The differences between emulsified oil and concentrate for hydraulic supports, and how to use emulsified oil for hydraulic supports.
Emulsified oil and concentrate for hydraulic supports are suitable as power transmission media for coal mines, single hydraulic props, hydraulic electric furnaces, and other similar systems. They can effectively protect hydraulic systems and extend their service life.

Henan Lubricant Franchise—Common Industrial Lubricant Categories and Their Functions
There are more than a dozen types of industrial lubricants, categorized into various models, with hundreds of different formulations available. Many manufacturing companies’ customers often consult us, unsure about how to choose the right industrial lubricant. Next, let’s take a look at the common classifications and functions of industrial lubricants—franchising in Henan for lubricants.

Henan Lubricant Oil Franchise—Lubricant Oil Production Processes and Methods
Industrial lubricating oils are widely used with various base oils, such as pure mineral oil, foam-inhibited synthetic hydrocarbon oils, polyether synthetic oils, alkylbenzene oils, and biodegradable oils. When these oils serve as industrial lubricants, they must not be mixed with each other. For example, when a polyether synthetic oil is mixed with other industrial oils, its performance will significantly deteriorate. Industrial lubricant additives vary depending on the specific application scenario. Outdoor hydraulic oils must be formulated to suit local temperature fluctuations and should never be used in enclosed indoor environments. Moreover, the requirements for heavy-duty gear oils differ from those for forming oils; heavy-duty gear oils contain extreme-pressure additives to ensure reliable performance even under harsh operating conditions.

Henan Lubricant Franchise—Classification of Automotive Lubricant Grades
Generally, the labels on lubricants display the viscosity grades established by the Society of Automotive Engineers (SAE). This is a viscosity classification system that divides lubricants into three categories: summer high-temperature types, winter low-temperature types, and all-season types suitable for both winter and summer conditions. Specifically, there are 6 winter-grade oils, 4 summer-grade oils, and 16 all-season oils. Next, let’s take a look at the classification levels for automotive lubricants offered by Henan Lubricant Franchise—Lubricant Levels for Automobiles.

Selection of Cutting Fluids, Classification of Oil-Based Cutting Fluids
Oil-based cutting fluids based on mineral oil are semi-synthetic oil-based cutting emulsions that also contain mineral oil. Cutting fluids containing chemically synthesized base oils, such as fully synthetic cutting fluids, on the other hand, contain only chemically synthesized base oils and no mineral oil.

What are the basic principles of oil-based cutting fluids?
Oil-based cutting fluids are typically formulated using highly refined mineral oils and synthetic base oils, combined with a scientifically engineered blend of extreme-pressure additives, rust-inhibiting antioxidants, anti-fog agents, and other components. They can be adapted to various metalworking processes.
Oil-based cutting fluid: How should cutting fluids be managed?
Oil-based cutting fluids can be stored for several years, whereas water-based cutting fluids can only be stored for 6 to 12 months. Cutting fluids should be stored indoors whenever possible, at a temperature between 5 and 40°C. If stored outdoors, avoid direct sunlight and exposure. In summer, outdoor temperatures in some regions can rise significantly, which is harmful to cutting fluids and may easily cause them to deteriorate. Additionally, it’s important to prevent rainwater from entering. Mixing rainwater with oil-based cutting fluids will reduce their lubricity and rust-preventive properties; mixing rainwater with water-based cutting fluids may lead to the separation or gelation of additives. The pour point of oil-based cutting fluids generally does not exceed -5°C, and the safety of water-based cutting fluids is typically guaranteed at temperatures as low as -5°C. Generally speaking, in southern regions...

The two main functions of oily cutting fluids used in machining
Commonly used oil-based cutting fluids can be divided into two main categories: one is primarily a cooling water solution, and the other is mainly a lubricating oil. Water solutions that emphasize cooling are typically emulsions—similar to milk—as seen in factories. They are used in rough machining to enhance the effectiveness of cooling techniques, thereby improving machining efficiency and extending tool life. Oil-based cutting fluids that prioritize lubrication—such as those used in total-loss lubrication systems, kerosene, oleic acid, and rapeseed oil—are designed to improve lubrication performance, ensure the surface finish quality of machined materials, and reduce tool wear costs.
