Change the oil, how to choose the right way to spend?

Engine oil, the engine oil, is known as the "blood" of the car, which can lubricate, clean, cool, seal, and reduce the engine. Changing oil is an important item in car maintenance and a relatively large expense in addition to fuel costs. Whether it is through 4S shop, auto parts market or professional oil brand maintenance store, consumers will inevitably encounter some consumption pits or â€œpitâ€ that are not easy to detect. Here we have a few tricks, and strive to allow owners to choose the consumption method that suits them relatively transparently.

First, in the 4S shop to replace expensive but save trouble

4S shop maintenance staff generally recommend the owner to use the original engine oil, and call this "designated engine oil." Most car brands 4S stores require customers to use the original engine oil during the warranty period. If other brand oils are used or oil is changed outside the 4S shop, the engine will not be warranted if there is any problem during the warranty period.

Blind Zone 1: What is the original oil in the oil?

Explanation: The essence is mineral oil, but the same price can reach the semi-finished oil on the market.

Du Yongchang, an associate professor at Tsinghua University's Tsinghua Automotive Engineering Development Research Institute, said that from the perspective of cost, most 4S stores currently use mineral oil. In fact, 4S stores use their dominant position in the automotive maintenance market to mislead customers. Get high profits.

It is true that the â€œoriginal special engine oilâ€ provided by 4S shop is basically in line with the requirements of the brand vehicle engine. The probability of supplying counterfeit and shoddy products is also very low, and the owner can use it with confidence. But the price of mineral oil in 4S stores is enough to buy semi-synthetic motor oil on the market.

Jiang Yong, the after-sales service manager of Guangbenhua Township Store, said that its â€œoriginal engine oilâ€ is actually an oil supplier based on the characteristics of each manufacturer's own engine. It adds a proper proportion of anti-high temperature and anti-corrosion on the basis of a certain brand of engine oil. Additives. â€œThe original engine oil marked with 'Honda' is still mineral oil in nature, just adding a tailor-made additive formula.â€

At present, many 4S stores also recommend high-quality synthetic motor oil to the owners, but the same brand, 4S shop is about 1/3 higher than the price of the oil brand franchise.

Blind Zone 2: Free replacement of ordinary engine oil, higher price synthetic oil at the expense of replacement

Weapons: Consult clearly before replacement, check maintenance details after replacement

Some 4S stores use the original engine oil when they change the oil for free during the first insurance period. However, when the customer needs to replace it at their own expense, they will recommend or directly replace the semi-synthetic or fully synthetic oil at a higher price.

Before the owner pays at his own expense, it is best to ask about the type and price of the oil. After the replacement, carefully check the cost details. It is recommended to keep the documents of the first insurance. You can compare the difference between the original engine oil and the synthetic oil. Situational choice.

In addition to Mercedes-Benz, Audi and other high-end brand models, such as Shell, Castrol and other brand products as the designated engine oil, the general family car with ordinary mineral oil can be.

Blind Zone 3: Old engine oil is deliberately not finished, leaving a small amount of new engine oil

Weapons: When you put oil, watch it for 10 minutes. After the change, ask for the used oil bottle.

Some small repair stations with poor reputation and a small number of 4S shop maintenance trade unions steal oil, that is, the old oil is deliberately not finished. When adding new oil, it is not necessary to fill 4 liters, resulting in a balance. They usually swallow 1 to 2 liters.

In fact, it is not possible to completely clean the old oil. The general error is normal in the range of 0.5L. If you have time, it is recommended that the owner watch the worker open the oil plug and completely leave the old oil and leave. This time will not exceed 10 minutes. In addition, if the 4S shop does not actively present the used oil bottle, the owner has the right to request an inspection.

Second, auto parts city bargains cheap but high risk

Auto Parts City is undoubtedly a good place for everyone to think about bargaining. However, in the mixed auto parts market, there are a lot of parallel imports and fakes.

Chief Engineer Chen of a car maintenance company in Guangzhou told reporters that some people have bought the bottles of famous brand oils such as Mobil and Shell at a price of 30 yuan. It can be expected that some oil fakes will exist in the market, among which Part of it is sold under the name of â€œparallel importsâ€.

Most of the parallel engine oils sold in the market in recent years come from Thailand, Taiwan and other places. Unscrupulous merchants use the mentality of people who are eager to get cheap and want to get imported oil. They use counterfeit motor oil to counterfeit brand oils sold abroad. In fact, this kind of oil that is half the price of the market is really high.

Once the so-called "parallel imports" are inferior oils, they will cause great damage to the engine and even scrap them due to their inconsistent viscosity and lack of various additives (even the old oil removal and de-coloring). Will not be worth the candle.

At the same time, don't forget that buying products that knowingly evade taxes will have the risk of breaking the national laws.

Third, find the brand maintenance store assured and cost-effective

At present, many brand oils have established their own brand car maintenance stores in China. If you want to buy better brand oil for some high-end brand models, the price of products purchased at these maintenance stores will be about 1/3 lower than that of 4S stores. But these oils are more expensive than ordinary mineral oil.

Fourth, self-purchase replacement requires a certain amount of hands-on ability

At present, some car owners and car clubs are popular with DIY oil change activities. Previously, clubs bought oil from branded oil distributors in the form of group purchases, with a lot of discounts. This is the most cost-effective method. Some 4S shops have held small competitions to teach owners to change their own oil. Interested car owners can try.

Precision Steel Tube are produced by Cold Drawn and Cold Rolling, with very good OD and ID tolerance and smoothness ,

with very good Concentricity, Good Roundess, Less Deviation, suitable for machinery.

Cold Drawn Seamless tubing (also known as CDS steel tube. Cold Drawn Seamless tubes offer tight tolerances compared to Hot Finished Seamless tube, and offers stronger physical properties compared to other mechanical tubing.

CDW Steel Tubes is made by drawing the ERW tubes from the tube mills through a plug and die combination, mounted on the draw bench. The end tagged and annealed tubes are drawn through a closely machined die that controls the outside diameter of the tubes. At the same time the tube passes over a plug that controls the inside diameter. Further, the manufactured tubes are processed by the downstream facilities for different industry applications.
