What oil does an excavator use? Hot topics and practical guides across the Internet
Recently, "What kind of oil should an excavator use?" has become a hot topic in the field of construction machinery, triggering widespread discussions especially on short video platforms and industry forums. This article will combine the hot content of the entire network in the past 10 days to provide you with a detailed analysis of the oil consumption standards of excavators and provide structured data reference.
1. Full analysis of oil types used in excavators
| Oil type | Applicable parts | Recommended label | Replacement cycle |
|---|---|---|---|
| engine oil | engine | CI-4/CJ-4 15W-40 | 500 hours/6 months |
| Hydraulic oil | Hydraulic system | AW46/HM46 | 2000 hours/1 year |
| gear oil | Slewing mechanism/traveling mechanism | GL-5 85W-90 | 1000 hours/1 year |
| Grease | Each lubrication point | Lithium grease NLGI-2 | weekly supplement |
2. Recent hot topics of discussion
1.The impact of National VI emission standards on oil products: The latest data shows that the search volume for CK-4 grade engine oil suitable for National VI emission engines has increased by 35% year-on-year, becoming a new hot spot in the industry.
2.Hydraulic oil mixing controversy: A short video blogger’s video of actually testing the failure caused by mixing different brands of hydraulic oil received 1.2 million views in 10 days, triggering widespread discussions on oil compatibility.
3.Winter oil selection: As the temperature in the northern region cools down, e-commerce sales of 10W-30 low-viscosity engine oil increased by 65% month-on-month. Experts recommend choosing the appropriate viscosity based on the ambient temperature.
3. Comparison of key indicators for oil product selection
| Performance indicators | High quality oil characteristics | Risks of inferior oil products |
|---|---|---|
| Viscosity index | >95 (good high temperature stability) | Viscosity instability leads to wear |
| total base number | 8-10 (neutralizes strong acidity) | Accelerate engine corrosion |
| flash point | >230℃ (high safety) | Flammable and volatile |
| Anti-emulsification | <30 minutes (fast water separation) | Oil sludge blocks the filter element |
4. Expert advice and user measured data
1.Brand selection trends: Industry research shows that the top three oil brands preferred by excavator users are Shell (38%), Mobil (32%), and Great Wall (18%).
2.Economic comparison: Measured data from an engineering team shows that although using high-grade oil is 30% more expensive, the equipment overhaul cycle is extended by 50% and the overall cost is reduced by 15%.
3.Authentic and fake identification methods: Genuine oil products should have: ① Laser anti-counterfeiting label ② Batch traceability code ③ Designated dealer certificate. Recently, anti-counterfeiting videos have been played more than 2 million times.
5. Oil usage plans under different working conditions
| Working condition type | Oil adjustment suggestions | Special precautions |
|---|---|---|
| High temperature environment | Use SAE50 engine oil | Increase the frequency of oil testing |
| High workload | Improve oil grade (such as CH→CI) | Shorten replacement cycle by 20% |
| dusty environment | Strengthen air filter maintenance | Use engine oil with detergent |
| cold areas | Switch to 5W/10W low viscosity oil | Preheat the oil pan before starting |
Conclusion:The correct choice of excavator oil can not only improve the performance of the equipment, but also significantly extend its service life. It is recommended that users select high-quality oil products from regular channels according to the requirements of the equipment manual and specific working conditions, and establish a scientific oil management system. In the near future, the industry will hold a number of online oil knowledge lectures, which are worthy of the attention of practitioners.
