It is cheaper to raise "heart" synthetic oil for semi-trailer

Recently, after visiting a number of repair shops and private semi-trailer owners, the reporter found two trends in the use of oil: first, everyone believed that semi-trailer maintenance should use good oil, for example, many people have replaced synthetic oil for their semi-trailer; Second, select appropriate engine oil products according to the conditions of semi trailer vehicles. For example, unified energy sharing mileage maintenance is popular.

During the visit, the reporter clearly felt that the semi-trailer owner was becoming more and more rational in the maintenance of semi-trailer. With the accumulation of knowledge and experience in maintaining semi-trailer, many semi-trailer owners have been able to choose their own oil for their favorite semi-trailer. They generally realize that the engine is the "heart" of the automobile and semi-trailer. The most important thing for semi-trailer maintenance is the care of the engine, and the most important way to maintain the engine is of course to make it get the most effective lubrication. Proper use of engine oil can not only prolong engine life, but also save fuel, otherwise it will be counterproductive. Good engine oil, especially synthetic engine oil, can not only protect the engine and reduce oil change times, but also save gasoline costs. If you choose improperly or just want to buy low-quality products cheaply for a while, it will cause early wear of the engine, reduce the service life of the engine, and even lead to "scuffing, holding" and other malignant accidents in serious cases.

The use of good engine oil, especially synthetic engine oil, is essential to help the vehicle. Mr. Wang, a taxi driver in Jiangxi, is particularly representative. He has a proud record of driving more than 1 million kilometers without major repair, In recent years, he has been using a kind of "fuel saving lubricating oil" "In fact, it is a synthetic engine oil with energy-saving effect. According to the reporter, this engine oil is the unified hybrid SM5W/30 product that has just been reviewed by the Ministry of Communications for energy-saving products. Wang Shifo thinks that compared with private semi trailers, taxi semi trailers start and brake frequently every day, which is especially serious for the engine, and the choice of engine oil is very important. According to Wang Shifu, "The life of a family is tied to this semi-trailer. One less repair will not only save money for semi-trailer repair, but also make more money for the time saved for semi-trailer repair. It is easier to use good oil."

The maintenance is different for different mileage. The maintenance is more convenient by mileage

When it comes to the selection of engine oil, maintenance experts suggest that the semi-trailer owner should follow the actual situation of the semi-trailer and choose the most appropriate engine oil product. The oil performance required by semi-trailer vehicles will be different due to different working conditions, engine types and driving ranges. For example, for semi-trailer owners who often prefer high speed gearshift semi trailers, if they run at high speed for a long time, the working temperature of the engine will remain high. Therefore, it is better for such semi-trailer owners to use heat-resistant oil, such as SAE15W-50 and SAE10W-40 models to achieve better heat dissipation; If the semi-trailer is in a cold working environment for a long time, because the viscosity of the oil itself is high at low temperatures, you can consider using some thinner oil, such as SAE5W-30.

From the mileage of semi trailers, the engine wear of semi trailers that run more miles is different from that of semi trailers that run less. At this time, mileage maintenance is required, which is like a doctor's "suit the remedy to the case". Patients will recover faster after taking the correct medicine. For example, the engine parts of an automobile semi-trailer traveling 50000 km and a automobile semi-trailer traveling 100000 km have different wear levels, and the oil required will also be different.

The first few thousand kilometers of a new semi-trailer is called the running in period. At this stage, the tiny protrusions on the parts will be worn off, making the fit clearance of each moving part closer and the movement more smooth. During the running in period, it is better to consider the use of lubricating oil products with good running in and anti-wear protection performance. Old semi trailers and semi trailers with long mileage may accumulate more carbon, paint film and sludge on the engine due to their long service life, which requires lubricating oil with strong cleaning ability and durable protection.

At present, what is better in this respect is Uni President Engine Oil. Its M-series products are divided into products within 50000 km, 50000 km to 100000 km, and more than 100000 km according to the driving mileage of semi trailers, as well as those corresponding to operating semi trailers. If the mileage of semi-trailer is less than 50000 km, M5 product can be used. If the semi-trailer has driven 80000 km, M5+products (SM5W-40 or SL10W-40) can be selected. These two products have good effects on sludge removal and cleaning respectively.
