Attention should be paid to the quality of excavator oil replacement

The quality of oil used in excavators greatly affects their lifespan and maintenance costs. Many unscrupulous oil dealers have sold inferior engine oil, causing huge losses to many excavator users. So, when changing the oil of an excavator, it is important to pay attention to the quality of the oil.

Mr. Ma and his wife from Ningxia took out a loan of 1 million yuan two years ago and purchased a car in Yinchuan with a total price of 1.3 million yuanKobelco excavatorMr. Ma said, "I still have one year left to repay the loan, but the engine is almost useless because I changed the oil once." On July 11th of this year, Mr. Ma purchased a bucket of Kobelco oil from a parts store near the Manchun Hotel. After filling it for more than ten days, on August 1st, the engine made a strange noise while working. After inspection by the 4S store maintenance personnel, it was found that the internal parts of the engine were severely worn. The maintenance engineer believes that this should be related to the engine oil used. And the repair requires 110000 yuan.

In order to clarify the issue with the engine oil, Mr. Ma sent the remaining engine oil to the Autonomous Region Chemical Product Quality Supervision and Inspection Station for testing. "The inspection fee was over 1400 yuan, and later it was found that two indicators did not meet the requirements. The final conclusion was that the engine oil was unqualified." In the inspection report he issued, he clearly pointed out that the pour point of the engine oil (the lowest temperature at which the cooled sample can flow) was too high and the viscosity exceeded the normal standard. Later, Mr. Ma filed a complaint with the industrial and commercial department, but the seller of engine oil has not promised compensation.

The staff of the 4S store mentioned above said, "We have checked the barrel of engine oil that Mr. Ma bought, and the packaging used was already discontinued last year. Such products should not appear in the Ningxia market." He also emphasized that Kobelco engine oil is a specialized engine oil, and the manufacturer only provides it to 4S stores around the world. It is impossible for other channels to have it in stock. In addition, the appearance and texture of the oil drum purchased by Mr. Ma are significantly different from the genuine product.

This excavator can work for 20000 hours under normal maintenance, while Mr. Ma only needs a major overhaul after 4000 hours of use, and the repair cost is as high as 110000 yuan. Mr. Ma also wanted to protect his rights through legal means, but after consulting three lawyers, he almost gave up on this idea. If I want to sue, I have to provide relevant inspection reports, and the engine inspection cannot be done here in Ningxia. It can only be done in other places, and the cost is higher than the repair cost. I don't know what to do now. It is understood that the mediation and negotiation work of the industrial and commercial department is still in progress.
