What grade of diesel does the excavator use? Network-wide hotspot analysis and practical guide
Recently, with the acceleration of infrastructure projects and agricultural production, "excavator diesel grade selection" has become a hot topic across the Internet. This article combines popular discussions and industry data in the past 10 days to provide you with a systematic analysis of the selection criteria, precautions and market trends of excavator diesel.
Excavators are usually usedNo. 0, -10, -20, -35 diesel, the specific selection depends on the ambient temperature and engine requirements. The following is a comparison of mainstream labels:
| Diesel grade | Applicable temperature | Features |
|---|---|---|
| No. 0 diesel | Above 4℃ | Good economy, commonly used in summer |
| -No.10 diesel | -5℃ to 4℃ | Moderate low temperature resistance |
| -No. 20 diesel | -14℃ to -5℃ | Mainstream choice in northern winter |
| -No. 35 diesel | -29℃ or below | Special for extremely cold areas |
In recent discussions on social platforms, the following questions have been the most popular:
1. “High-grade diesel is more fuel-efficient?”Experts point out that blindly choosing high-grade diesel not only increases costs, but may also lead to carbon deposits due to insufficient combustion.
2. “Are there any risks in mixing diesel?”Mixing different grades will have less impact in the short term, but it may damage the high-pressure pump and injector in the long term.
3. “How to choose under the National VI standards?”National VI excavators need to match diesel with a sulfur content of ≤10ppm, otherwise the emission alarm may be triggered.
According to the latest data in May, national diesel prices show regional differences (unit: yuan/liter):
| area | No. 0 diesel | -No.10 diesel | Increase or decrease |
|---|---|---|---|
| East China | 7.45 | 7.89 | ↑0.3% |
| North China | 7.32 | 7.76 | ↓0.2% |
| South China | 7.58 | 8.02 | flat |
1. Temperature priority principle:When the temperature is lower than -5℃, you must switch to -10 or above diesel to avoid solidification and blocking the oil line.
2. Brand selection:Oil products from formal channels such as Sinopec and PetroChina are more stable, but diesel from small refineries may contain impurities.
3. Maintenance tips:The diesel filter needs to be replaced every 250 hours, and it is recommended to install an oil-water separator for National VI models.
Conclusion:The choice of excavator diesel grade directly affects equipment life and operating efficiency. It is recommended that machine owners make scientific decisions based on actual operating conditions and recent changes in oil prices. If you need further data, you can pay attention to the National Development and Reform Commission’s refined oil price adjustment notice every Wednesday.
