What oil is used for construction machinery? Comprehensive analysis and purchasing guide
In the daily use of construction machinery, the choice of engine oil is directly related to the performance, life and operating efficiency of the equipment. With the advancement of technology and the improvement of environmental protection requirements, the engine oil market is also constantly updating. This article will combine popular topics and hot contents across the network for the past 10 days to analyze the principles, common models and recommended brands of engineering machinery oil for you in detail to help you make wiser choices.
1. Classification and function of engineering machinery oil
Engine oil mainly plays a role in lubrication, cooling, cleaning and rust prevention in construction machinery. According to the different base oil, engineering machinery oil can be divided into three categories: mineral oil, semi-synthetic oil and fully synthesized oil:
| Engine oil type | Features | Applicable scenarios |
|---|---|---|
| Mineral oil | Low price, but poor durability, short replacement cycle | Small construction machinery or low-load operations |
| Semi-synthetic oil | Performance balanced, cost-effective | Medium-heavy-duty engineering machinery |
| Fully synthetic oil | High temperature resistance, strong wear resistance, long replacement cycle | High load, harsh environment operations |
2. Selection of engine oil viscosity grade
The viscosity grade of the engine oil (such as SAE 15W-40) directly affects its flow performance at high and low temperatures. Commonly used viscosity levels in construction machinery are as follows:
| Viscosity grade | Applicable temperature range | Recommended Machinery Type |
|---|---|---|
| SAE 10W-30 | -20°C to 30°C | Small excavator, loader |
| -15°C to 40°C | endsMedium-sized excavator, bulldozer | |
| SAE 20W-50 | -10°C to 50°C | Heavy trucks, mining machinery |
3. Recommended popular oil brands
According to the search data of the entire network in the past 10 days, the following brands of motor oil have attracted much attention in the field of engineering machinery:
| brand | Celebrity Products | Consumer Reviews |
|---|---|---|
| Shell | Rimula R4 | tidesExcellent lubrication performance, suitable for high-load operations |
| Mobil | Delvac 1300 | Strong low-temperature starting performance, suitable for cold areas |
| Castrol | Vecton | Strong wear resistance and extend engine life |
4. Things to note when purchasing engine oil
When purchasing engineering machinery oil, in addition to paying attention to the brand and viscosity grade, you should also pay attention to the following points:
-Matching equipment instruction manual: Different brands and models of construction machinery have different requirements for engine oil, so be sure to refer to the manufacturer's recommendation.
-Pay attention to API level: For example, CI-4, CK-4, etc., the higher the number, the better the environmental protection and performance of the engine oil.
-Regular oil change: Even if fully synthetic engine oil is used, it must be replaced according to the recommended cycle to avoid oil deterioration affecting the equipment.
5. Conclusion
Choosing the right engine oil can not only improve the working efficiency of construction machinery, but also reduce maintenance costs. I hope that through the analysis of this article, you can have a clearer understanding of how to choose the right engine oil for your equipment.
