What hydraulic oil does excavator use? Hot topics and professional analysis on the entire network
Recently, among the hot topics in the field of construction machinery, "Excavator Hydraulic Oil Selection" has become the focus of industry attention. With the arrival of the peak of construction in the high temperature and rainy season in summer, the impact of hydraulic oil performance on equipment has sparked widespread discussion. This article will combine hot data on the entire network for nearly 10 days to provide you with structured analysis.

2. Hydraulic oil core parameter comparison table
| Oil type | ISO viscosity grade | Applicable temperature range | Mainstream brands |
|---|---|---|---|
| Mineral hydraulic oil | VG32/46 | -10℃~50℃ | Shell/Great Wall |
| Semi-synthetic hydraulic oil | VG46/68 | -25℃~70℃ | Mobil/Kunlun |
| Fully synthetic hydraulic oil | VG68/100 | -40℃~90℃ | Castrol/Dordal |
3. Key factors for hydraulic oil selection
1.Ambient temperature adaptation: Recently, there has been high temperatures in the south. It is recommended to choose VG68 and above viscosity grade oil products. Multi-stage hydraulic oil should be considered in areas with large temperature differences in the north.
2.Equipment condition matching: According to a brand's 2023 technical white paper, under continuous operation conditions, the hydraulic oil temperature of 20-ton excavator can reach 80℃, and synthetic oil with better oxidation resistance is required.
3.Economic balance: Data from e-commerce platforms show that the price range of mineral oil is between 80-150 yuan/liter, and the price of synthetic oil is between 200-400 yuan/liter, but the oil change cycle can be extended by more than 50%.
4. Industry experts' suggestions
The latest guidance of the China Engineering Machinery Association points out:New bio-based hydraulic oilIt has become a recent technical hotspot, and its degradation rate can reach more than 80%, which is particularly suitable for construction projects with strict environmental protection requirements.
The actual data released by a well-known maintenance team through a short video platform shows that improper use of hydraulic oil will causeThe wear rate of hydraulic pump increases by 3 times, the system failure rate increased by 47%.
5. Performance comparison of mainstream products in the market
| brand | Anti-wear index | Antioxidant | Price (yuan/liter) |
|---|---|---|---|
| Shell Tellus | 420N | 1500h | 320 |
| Mobil DTE | 450N | 1800h | 380 |
| Great Wall L-HM | 380N | 1200h | 260 |
6. Operation and maintenance suggestions
1. According to the requirements of the equipment manual,Every 2000 working hoursorReplace at least once a year
2. Special attention should be paid to rainy areas in the near futureMoisture content detection, the moisture content exceeds 0.1% should be replaced immediately
3. Mixed use of different brands of hydraulic oil may causeAdditive chemical reaction, it is recommended to clean the system thoroughly and replace it
Current industry data shows that the correct choice of hydraulic oil can extend the life of the excavator hydraulic system by more than 30%, saving about 15% of repair costs per year. It is recommended that users choose the most suitable hydraulic oil solution based on actual working conditions and recent climate characteristics.
