What kind of oil is usually added to excavators? Analysis of hot topics and hot content across the entire network

Recently, among the hot topics about construction machinery maintenance, "what kind of oil is usually added to excavators" has become the focus of discussion. This article will combine hotspot data from the entire network in the past 10 days to provide you with a detailed analysis of excavator oil specifications, and attach structured data for easy reference.

1. Excavator oil types and standards

What kind of oil is usually added to excavators?

Oil typeRecommended labelReplacement cycleApplicable parts
diesel fuel0#/-10#/-35#Add as you gofuel system
engine oilCI-4/CJ-4500 hoursengine
Hydraulic oilHV46/HV682000 hoursHydraulic system
gear oilGL-5 85W-901000 hoursslewing mechanism

2. Correlation analysis of hot topics across the entire network

According to big data monitoring, relevant discussions in the past 10 days have mainly focused on:

1.Winter oil selection: Northern users are concerned about the compatibility issue between -35# diesel and low-temperature hydraulic oil, and related topics have been read more than 1.2 million times.

2.Identification of authenticity of oil products: The topic "Oil Testing Comparison" on a short video platform has been viewed 8.5 million times, of which excavator-specific oil accounts for 37%.

3.Impact of environmental policies: After the implementation of China IV emission standards, searches for CI-4 and above engine oils increased by 65% ​​year-on-year.

3. Common misunderstandings in the use of oil products

MisunderstandingCorrect approachPotential hazards
Mixing diesel and engine oilStrictly distinguish between fuel and lubrication systemsEngine cylinder
Failure to change hydraulic oil for a long timeReplace and clean the fuel tank on timeHydraulic pump wear
Use low grade gear oilAdd as required in the manualAbnormal noise in rotation

4. Expert advice and maintenance points

1.Brand selection: Recommend big brands such as Shell, Mobil, and Great Wall to avoid using oils from unknown sources.

2.Replacement cycle: When the actual operating environment is harsh, the replacement cycle should be shortened by 20%, especially in dusty conditions.

3.Storage requirements: Diesel should be avoided for more than 3 months, and hydraulic oil should be used within 6 months after opening.

4.Oil testing: A rapid tester can be used to test the water content and impurity content of the oil every 250 hours.

5. Construction machinery oil consumption trends in 2023

According to industry reports:

trend directionMarket shareannual growth rate
Fully synthetic motor oil28%12%
Biodegradable hydraulic oil15%25%
Long cycle oil products42%8%

With the advancement of technology, new nano-additive oil products have begun to be trialled in high-end models of Komatsu, Carter and other brands, and are expected to enter the popularization stage in 2024.

Conclusion:Proper selection and maintenance of excavator oil can not only extend the life of the equipment, but also significantly reduce operating costs. It is recommended that machine owners establish complete oil usage files and conduct regular oil testing to ensure that the equipment is always in optimal working condition.
