With the progress and development of society, people pay more and more attention to the protection of the environment and the improvement of energy efficiency, which promotes the advancement of lubricant technology and the upgrading of lubricant products by lubricant manufacturers. Better fuel economy, less exhaust emissions, longer drain intervals, and an increasingly harsh operating environment in the engine are prompting people to continuously develop and upgrade various additives to cope. Against this background, organic molybdenum additives that combine anti-friction, energy saving, and anti-corrosive properties have been developed, setting off waves in the industry. In recent years, organic molybdenum additives and organic molybdenum-containing composite agents have been used more and more in internal combustion engine oils, especially gasoline engine oils.
The important part of the car is the engine, and in order to better reflect the performance of the engine and extend the service life of the engine, most people now start to pay attention to the lubricant used in each maintenance. How to choose a good lubricant? This is a question that many people will ask. Let me introduce some basic knowledge of lubricants.
Use a high viscosity lubricant and start it at a low temperature, because after a period of shutdown, the lubricant on the friction surface has been lost, and the viscosity is high, and the fluidity is slow. It cannot be added to the friction surface in time to form a lubricant film, so it will cause The parts are in dry friction and semi-dry friction conditions for a long time, which leads to increased wear of the parts.
In fact, in terms of wear resistance, oxidation resistance, and other performance characteristics of lubricant manufacturers, low-quality lubricants are inferior to high-quality lubricants and cannot meet the requirements for safe use of new engines. If you choose SG and SF lubricants for a standard SJ-grade engine, it will cause abnormal engine wear, shorten the service life of the engine, and increase maintenance costs. It is extremely unwise to use too low-grade or inexpensive fake and inferior lubricants.
