What oil should be added to the loader? Comprehensive analysis of fuel, hydraulic oil and lubricating oil selection guide
With the wide application of construction machinery, loaders are common heavy equipment, and their care and maintenance have become a hot topic for users. In the past 10 days, "What oil should be added to the loader?" has become one of the hot topics on the Internet, especially new operators who have many questions about oil selection. This article will start from the three major categories of fuel, hydraulic oil and lubricating oil, combined with the latest discussion data from the entire network, to provide you with structured answers.
1. Loader fuel selection standards
Fuel is the core of loader power, and different grades of diesel fuel need to be used under different ambient temperatures. The following are fuel adaptation suggestions that are hotly discussed across the Internet:
| ambient temperature | Recommended diesel grade | Flash point requirements |
|---|---|---|
| >4℃ | 0#diesel | ≥55℃ |
| -5℃~4℃ | -10# diesel | ≥50℃ |
| -14℃~-5℃ | -20# diesel | ≥45℃ |
| -29℃~-14℃ | -35# diesel | ≥45℃ |
| ＜-29℃ | -50#diesel | ≥40℃ |
2. Hydraulic system oil selection
According to the data analysis of the industry forum in the past 10 days, the selection of hydraulic oil needs to focus on the viscosity grade and anti-wear performance:
| Equipment working conditions | ISO viscosity grade | Typical brand recommendations |
|---|---|---|
| Normal temperature working condition (-10~40℃) | HM46 | Shell Tellus, Mobil DTE |
| High temperature working condition (>40℃) | HM68 | Great Wall Zhuoli, Kunlun Tianhong |
| Extremely cold conditions (<-20℃) | HV32 | Castrol Hyvol, BP Energol |
3. Key data of lubrication system
The lubricating oil replacement cycle of various parts of the loader has become a frequent search engine issue recently. The recommendations in the manufacturer's technical manual are summarized as follows:
| Lubrication parts | Oil type | Replacement cycle |
|---|---|---|
| engine oil | CI-4 15W-40 | 250 hours/6 months |
| transmission oil | TO-4 standard oil | 1000 hours |
| Transaxle gear oil | GL-5 85W-90 | 2000 hours |
| Articulation bearing | Lithium grease | weekly supplement |
4. Common misunderstandings in the use of oil products
Based on recent social media discussions, three common misunderstandings have been sorted out:
1.Mixing different brands of hydraulic oil: Different brands of additive formulas may produce chemical reactions, causing hydraulic system failure.
2.Ignore oil filter replacement: A survey shows that 38% of loader failures are related to the extended use of oil filters. The replacement standard of 50 hours of pre-filtration and 250 hours of fine filter should be strictly followed.
3.No oil change in low temperature environment: When the ambient temperature is lower than -15°C, low-temperature hydraulic oil (HV series) must be replaced. Ordinary hydraulic oil will cause abnormal system pressure due to increased viscosity.
5. Latest industry trends
The "2024 Loader Maintenance White Paper" recently released by the China Construction Machinery Industry Association states:
- The proportion of electric loaders increased to 18%, and their special coolant selection became a new hot topic
- After the implementation of the National IV emission standards, it is recommended to give priority to engine oils of CJ-4 and above levels.
- The market growth rate of bio-based hydraulic oil is 27%, which is suitable for construction scenarios with strict environmental protection requirements.
Through the above structured data analysis, I hope it can help you scientifically choose loader oil. The correct oil selection can not only extend the life of the equipment, but also significantly reduce the failure rate. It is recommended to check the equipment manual regularly and pay attention to the latest technical announcements from oil suppliers.
