For turbocharged engines, synthetic engine oil must be used for maintenance. As for whether it is fully synthetic or semi-synthetic, it's up to you to choose. When the turbocharged engine works, the internal pressure of the engine is high, the direct friction of parts is large, and the engine temperature is higher than that of the self-priming engine, which requires stronger lubrication protection. Only synthetic engine oil can minimize engine wear. Synthetic engine oil is undoubtedly the best type of lubricating oil at present, and synthetic engine oil has better performance in oxidation resistance, high temperature resistance, low temperature fluidity, quietness and long-term effect, so synthetic engine oil is definitely the best choice for automobile maintenance, except for its high price. So, can synthetic engine oil maintain 15000 km? It's really possible. Synthetic engine oil has strong antioxidant capacity. With a reasonable formula, it is actually easy to reach the maintenance interval of1.5000 km. Now many engine oil brands have the slogan of changing oil for a long time, which shows that it is not impossible to change oil for a long time. To achieve the effect of long-term oil change, we must first choose the right engine oil, which is not available in all synthetic engine oil. Now the word "total synthesis" has been broken by merchants. Even mineral oil is all over synthetic engine oil, and many people pretend to be all over synthetic engine oil with semi-synthetic engine oil, so be sure to keep your eyes open when buying it. When buying, you must buy the top and sub-top product series of this brand, so as to ensure that it is genuine and fully synthetic, and the rest can be regarded as semi-synthetic engine oil.
