How do you choose excavator refueling? Diesel and excavator lifespan

The quality of diesel is closely related to the daily service life and stability of excavators. Many equipment owners use reliable diesel when refueling themselves. In China, the only diesel brands that can be used with confidence are Sinopec and PetroChina. But the price makes many construction sites choose private diesel, which is cheap and reduces costs. The cost savings that can be achieved for a large construction site in just one year from oil prices are very considerable. Nowadays, excavators generally adopt a leasing model, and many construction site owners are not concerned about how much damage the excavator brings. If there is a malfunction, it is often only the owner of the excavator who suffers losses.

　　“Private oil”The price of the equipment is relatively low, and even the equipment owner personally adopts it. Considering daily use to save costs also means increasing income. If it is a medium to large equipment, using it for one year only saves more than fuel expensesA real discount of over 20% or even more, which amounts to tens of thousands of yuan in cash per year. More conveniently“Private oil”Compared to Sinopec and PetroChina, transportation services have great advantages. Many construction sites are located in remote areas and transportation is difficult, often requiring only one phone call“Private oil”Being delivered to the place you need is not only convenient but also more convenient. This is also an important reason why many construction site owners like private oil.

Recently, Mr. Zhang from Xizang visited a CAT in HuachengThe 336E excavator was very satisfied in all aspects, but after communicating over the phone, I learned that the local oil quality could not meet the standards. If high-end electronic fuel injection excavators use inferior diesel, it may cause problems. I hesitated and finally had no choice but to sigh helplessly!

SinceAfter 2008, the reform of domestic or imported joint ventures in the power system adopted electronic fuel injection engines, which caused engine failures due to substandard oil quality. This has left most engine owners feeling hopeless, and even some places have immature conditions for purchasing from Sinopec and PetroChina, unless the high cost outweighs the loss. This is also the main problem that has led to the lagging development of electronic fuel injection in China.

Of course, it cannot be said that there are many problems with private oil. Most private oil in China can still meet the needs of direct injection and electronic injection excavators. Here, we mainly talk about the excessive addition of bad oil by bosses in diesel and the excessive impurities in diesel. The biggest inducement for frequent failures of electronic injection due to oil quality is nozzle failure, paint blockage failure, and dirtiness, which are the most common. The oil cost saved for several months will not only be repaired in the end, but also the problem of severe delays in the construction period, making it difficult to repair excavator failures, is not an isolated case.

How to distinguish the quality of oil? The most important thing when looking for private oil is to have a good reputation among peers. In procurement, try to purchase multiple barrels at once and reserve them. After sedimentation, check for diesel dirt, water content, and diesel color to identify.

If conditions permit and new equipment is available, HuachengSecond hand excavator marketIt is recommended to use Sinopec and PetroChina diesel, which will not cause any problems in terms of oil quality. Imported excavator equipment will continue to improve in terms of high-end technology and engine system upgrades. Diesel standards will become better and better, and electronic fuel injection, which has obvious fuel saving effects, must not cause irreparable losses to the equipment due to small profits.
