Many car owners believe that the structure of turbo vehicles is relatively complex compared to self-priming vehicles. turbocharged engine is added to the naturally aspirated engine to drive the turbine. It is precisely because of the special structure that models equipped with turbocharged engines generally require the use of full-synthetic oil during maintenance, but in fact, cars equipped with naturally aspirated engines should also use full-synthetic oil.
Before explaining why it is best to use fully synthetic oil for cars with naturally aspirated engines, let’s first understand the difference between fully synthetic oil and traditional lubricating oil.
The difference between fully synthetic engine oil and traditional lubricating oil
Traditional lubricating oil is just simple refining, that is, crude oil, and after refining, it forms a relatively low-grade base oil. After all, it is just a base oil, and there are still some particulate matter and impurities in it. This is why the oil sludge in , which is lubricated with mineral oil , will be heavier.
and fully synthetic engine oil In order to provide better wear protection and high temperature protection to the engine, additives such as detergents and dispersants are added to it. The detergent can neutralize the corrosiveness caused by acidic substances produced when burning high-sulfur fuel. The function of dispersant is to enable organic matter to be suspended in lubricating oil and reduce the problem of wear of parts caused by precipitates. Different fully synthetic engine oil manufacturers have their own patented products. Compared with traditional lubricating oils that have only been primary refined, the fully synthetic engine oil has a significantly more adequate protection for the engine.
Fully synthetic engine oil can better protect the engine
The higher the engine speed, the faster the internal parts will be moved aggravated. What if your driving habits are also radical? At this time, it is best to use fully synthetic engine oil, because the viscosity of fully synthetic engine oil of the same label will be higher than that of mineral oil. The oil film that can be formed on the surface of the engine parts with higher viscosity will be relatively thicker. When driving violently, the engine load will be larger, and the lubrication effect will be better.
Fully synthetic engine oil cost is lower
In fact, most cars that use full synthetic engine oil have been clearly marked in the maintenance manual that it is enough to do maintenance every 10,000 kilometers. The price of full synthetic engine oil is about 300 yuan. If you are using mineral oil, you need to maintain it every 5,000 kilometers, and the price is around 150 yuan. It seems that the cost of using fully synthetic engine oil and mineral oil is similar, but in fact it is not, because oil filter and labor costs must be included in the maintenance, and this does not count the time and round-trip oil costs of driving the car to the 4S store.
How to choose fully synthetic engine oil
Several parameters that need to be paid attention to when purchasing engine oil. The first point is high temperature viscosity, which is the "40" after "5W-40". Open the maintenance manual on the vehicle and check the recommended oil viscosity inside. If you recommend a type of 20, 30 or even 40, then buy it according to your driving habits. If you have a gentle driving habits, buy low viscosity engine oil. The lower the viscosity, the more fuel-efficient it is. If you have more aggressive driving habits, choose high viscosity engine oil, which also provides sufficient protection for the engine.
The second point is low-temperature viscosity, that is, "0W", "5W", etc. The smaller the number, the better the low-temperature fluidity of the engine oil, and it can reach the surface of the parts more quickly in a low-temperature environment. The smaller the number among the applicable oil types.
The third point is also something that everyone is more likely to ignore, which is the oil performance level. The latest ones are SP type engine oil, followed by SN and SM, so it is naturally the best to choose SP level.
is written at the end: I believe that after reading this article, you must also understand why priming vehicles also use fully synthetic engine oil. In fact, it is to bring better protection to the engine, and the second is to have better fuel economy and lower cost of car use and maintenance.It seems that buying full synthetic engine oil costs more than mineral oil, but in fact, it saves money.
