Many car owners want to change their car to a high-performance, worry-free engine oil. However, the choice of oil often results in various puzzles. For example:
What are the effects of different performance oils on engine operation, what kind of engine oil can stand the test of time, etc.
In fact, to answer these puzzles, we only need to focus on the four properties of the oil:
1) Wear resistance
2) Cleanliness
3) Low temperature fluidity
4) High temperature stability
• Wear resistance: Engine parts will continue to friction during high-speed movement, whether the lubricant can continue to form a protective barrier between the components.
• Cleanliness: Lubricants resist the formation of carbon deposits when they circulate in the engine.
• Low-temperature fluidity: When the car is extinguished for a period of time (for example, one night), the lubricating oil will solidify. After the car is restarted, the lubricating oil can immediately flow to reduce the friction of the engine components.
• High temperature stability: High temperatures can oxidize and thicken lubricating oils, causing them to pump around the engine, increasing engine wear. High temperature stability measures the ability of a lubricant to resist oxidation and thickening.
Having clarified the key performance of lubricating oil, what can be done well and how does it perform poorly?
If we classify oils with synthetic lubricants and mineral oils, synthetic lubricants are generally similar to the 'high-performance lubricants' mentioned in the above table, and their performance is relatively better than that of mineral oils.
Mineral oil is a refined crude oil. It is a crude oil that has been distilled, separated from steam, coal, and diesel oil, and after distillation and dewaxing into the base oil and additives are added. But subject to its chemical composition, minerals Although oil can meet the basic function of lubricating oil, it is still limited in many aspects of performance. For example, high temperature resistance and poor cleaning performance make it easy to pollute the environment.
Synthetic oil was born in the laboratory. It was synthesized using chemical methods. It comes from the gas or natural gas in crude oil. It is refined, distilled, purified and decomposed into basic molecules. It can then be reconstructed and improved with additives. The molecules of the synthetic oil are arranged neatly and have strong resistance to changes in the outside world. Therefore, they are superior in terms of high temperature stability, fluidity, and abrasion resistance.
In the long run, the benefits of using synthetic oils are even more obvious.
Xiao Bian thinks that in most cases, almost all automotive engines will benefit from the use of high-performance lubricants.
mainly reflects in:
A, reduce wear, reduce replacement of parts;
B. Reduce friction and reduce various energy consumption;
C. Extend the service life of oil and change oil intervals;
D. The lubricating protective film can maintain sufficient strength when the engine is running at a high temperature;
E, excellent thermal stability and oxidation resistance.
More and more consumers have realized that the oil change cycle of synthetic oil is more than 1 to 2 times more than that of mineral oil, and it also reduces the expenditure of 1-2 oil filters and oil change man-hours (uncalculated savings Time), so the use of fully synthetic lubricants has a direct and visible economics.
Secondly, taking synthetic lubricants as an example, its enhanced antifriction properties can effectively improve fuel economy and save fuel costs. Finally, it protects the engine. Synthetic lubricants can effectively reduce engine wear, reduce carbon deposition, and increase power. At the same time, it reduces engine failure, prolongs engine overhaul time, and reduces automobile consumption expenditures in all aspects.
