Recently, the topic of construction machinery maintenance has continued to heat up on major platforms, especially "what oil is used for excavators" has become a hot search keyword. This article will combine hot data across the network in the past 10 days to provide readers with a structured solution.
1. Current ranking of popular engine oil brands (based on sales of e-commerce platforms)
| Ranking | brand | Applicable models | Monthly sales (barrel) |
|---|---|---|---|
| 1 | Shell RIMULA | Below 20 tons | 8500+ |
| 2 | Mobil DTE 10 | Medium-sized excavator | 7200+ |
| 3 | Great Wall Zunlong T500 | Domestic models | 6500+ |
| 4 | Castrol SYNTRON | Cold areas | 5300+ |
2. Comparison table of core indicators for oil selection
| parameter | Standard value | Detection method |
|---|---|---|
| Viscosity grade | SAE 15W-40 | ASTM D445 |
| Total alkaline value (TBN) | ≥7.0 | ASTM D2896 |
| Flash point | ≥220℃ | ASTM D92 |
| Pour Point | ≤-25℃ | ASTM D97 |
3. Oil use schemes for different working conditions
Based on the recent heat of discussions in industry forums, we have compiled three typical scenarios of oil use suggestions:
| Working condition type | Recommended oil products | Replacement cycle |
|---|---|---|
| High temperature mines | Fully CI-4 level synthesis | 250 hours |
| Ordinary earth | CH-4-level semi-synthesis | 300 hours |
| Cold area operation | 5W-40 low-condensation engine oil | 200 hours |
4. The five most concerned issues for users
Based on Baidu Index and Zhihu hot list data, we have sorted out recent high-frequency questions:
1.Can domestic brands replace imported engine oil?Laboratory data shows that the key indicators of mainstream domestic brands are close to international standards, but there is still a gap under extreme operating conditions.
2.Do engine oil need to be replaced if it turns black?Recently, popular science videos on Douyin have emphasized that the cleaning and dispersive function of modern engine oil will naturally turn oil into black, and should be judged based on the number of hours.
3.Risk of mixed use of different brandsJD Car Maintenance Expert pointed out in the live broadcast that differences in base oil formulas may lead to precipitation, and emergency mixed use should not exceed 10% of the total amount.
4.Is the electronic dipstick accurate?Many manufacturers have posted comparative tests on WeChat official accounts, confirming that the electronic monitoring error rate is ≤3%, but it is recommended to manually review every 50 hours.
5.Oil consumption standardThe latest industry white paper shows that the fuel tank capacity is within the normal range for every 100 working hours.
5. Comparative analysis of maintenance costs
| plan | Single cost | Number of annual maintenance | Total cost |
|---|---|---|---|
| High-end full synthesis | RMB 2,800 | 4 times | RMB 11,200 |
| Mid-end semi-synthesis | 1800 yuan | 5 times | 9,000 yuan |
| Economical mineral oil | 1200 yuan | 6 times | 7200 yuan |
Conclusion:When choosing excavator oil, you need to comprehensively consider the equipment model, working conditions, environment and economy. It is recommended to conduct oil testing every quarter and make scientific decisions based on the latest technical standards.
