What kind of engine oil do modern excavators use? Comprehensive analysis of popular choices in 2024
With the rapid development of the construction machinery industry, modern excavators have increasingly higher performance requirements for engine oil. As the "blood" of the engine, engine oil directly affects the service life and work efficiency of the equipment. This article will combine the hot topics and user concerns on the Internet in the past 10 days to provide you with a detailed analysis of the selection standards, recommended brands and usage precautions for modern excavator oil.
1. Key indicators for the selection of modern excavator oil
According to discussions between construction machinery forums and industry experts, the following parameters need to be focused on when selecting engine oil for modern excavators:
| index | Recommended range | Importance statement |
|---|---|---|
| Viscosity grade | 10W-30/15W-40 | Adapt to different climate conditions to ensure low temperature start-up and high temperature protection |
| API level | CI-4/CJ-4/CK-4 | Meeting the lubrication needs of modern high-pressure common rail engines |
| Base number (TBN) | ≥7 | Neutralizes acidic substances produced by combustion and extends oil change intervals |
| Flash point | ≥220℃ | High temperature safety indicators to prevent premature evaporation of engine oil |
2. Recommendations for popular excavator oil brands in 2024
According to e-commerce platform sales data and user reviews, the following brands have attracted much attention recently:
| brand | Hot selling models | Price range (yuan/18L) | User rating (5-point scale) |
|---|---|---|---|
| Shell | Rimula R4 L 15W-40 | 800-950 | 4.8 |
| Mobil | Delvac 1300 Super 15W-40 | 850-1000 | 4.7 |
| Castrol | Vecton CI-4 15W-40 | 780-920 | 4.6 |
| Great Wall Lubricant | Zunlong T600 15W-40 | 600-750 | 4.5 |
| Kunlun lubricating oil | Tianwei CK-4 10W-30 | 650-800 | 4.4 |
3. Suggestions on engine oil selection under different working conditions
Based on recent test reports released by construction machinery self-media, we have compiled the following practical suggestions:
| Working condition type | Recommended oil characteristics | Oil change interval |
|---|---|---|
| High temperature environment (>35℃) | High viscosity index (such as SAE 20W-50), excellent oxidation resistance | 200-250 hours |
| Cold areas (＜-15℃) | Low pour point engine oil (such as 0W-30), excellent low temperature fluidity | 180-200 hours |
| High workload | High base number engine oil (TBN≥10), extreme pressure anti-wear additives | 150-180 hours |
| Old equipment | Contains a repair agent formula to moderately increase the viscosity level | Shorten cycle time by 20% |
4. Common misunderstandings and correct practices when using engine oil
There has been a lot of discussion on social media recently about the use of engine oil. We have summarized a few key points:
Misunderstanding 1:The more expensive the oil, the better →Correct approach:Choose engine oil that meets the standards specified by the manufacturer. Excessive pursuit of high prices may cause waste.
Misunderstanding 2:Can mix different brands of engine oil →Correct approach:Different formulas may cause chemical reactions, and in principle it is not recommended to mix them.
Misunderstanding 3:If the engine oil turns black, replace it →Correct approach:Modern engine oil contains detergents and dispersants. Blackening is normal and should be replaced according to hours or test results.
Misunderstanding 4:The higher the viscosity the better the protection →Correct approach:Too high viscosity will increase startup wear, so the appropriate viscosity should be selected according to the ambient temperature.
5. New trends in engine oil technology in 2024
Information obtained from recent industry exhibitions and technology forums shows:
1.Low ash content formula:In order to meet the National IV/V emission requirements, low SAPS (sulfur/phosphorus/ash) engine oil has become mainstream.
2.Long oil change intervals:New synthetic technology enables oil change intervals of more than 500 hours, reducing operating costs.
3.Intelligent monitoring:Works with sensors to monitor engine oil quality in real time, enabling on-demand replacement.
4.Bio-based motor oil:Environmentally friendly vegetable oil-based engine oils have begun to enter the field of engineering machinery.
Conclusion:Choosing a suitable excavator oil requires comprehensive consideration of the equipment model, working environment and technical requirements. It is recommended that machine owners conduct regular oil testing and establish a scientific maintenance plan. The data and suggestions provided in this article are all from recent industry trends, and we hope to provide a reference for your equipment maintenance.
