What antifreeze is best for excavators? Hot topics and purchasing guides across the Internet
With the arrival of winter, the maintenance of construction machinery has become a hot topic. Recently, the discussion on "antifreeze for excavators" has soared across the Internet. In particular, how to choose the right antifreeze, brand recommendations, and usage precautions have attracted much attention. This article will combine the hot data of the past 10 days to provide you with a structured purchase guide for excavator antifreeze.
1. Analysis of hot topics on the entire network (last 10 days)

| hot topics | Amount of discussions (articles) | main focus |
|---|---|---|
| Excavator antifreeze brand comparison | 3,200+ | Differences in performance of brands such as Shell, Mobil, and Great Wall |
| Antifreeze freezing point selection | 2,800+ | Applicable scenarios for different freezing points such as -35℃, -45℃ |
| Antifreeze replacement cycle | 1,500+ | Is it reasonable to replace it in 1 year or 2000 hours? |
| Risks of homemade antifreeze | 1,200+ | Cases of the dangers of tap water blending |
2. Core indicators for purchasing antifreeze for excavators
According to the advice of construction machinery forums and experts, excavator antifreeze needs to focus on the following five indicators:
| index | Standard requirements | Risk of inferior products |
|---|---|---|
| freezing point | More than 10℃ lower than the local minimum temperature | Ice swelling and cracking engine block |
| boiling point | ≥108℃ (for heavy machinery only) | Boiling the pot at high temperatures causes a decrease in power |
| Anti-corrosion | Contains organic acid corrosion inhibitor (OAT technology) | Corrosion of metal parts such as water pumps and cylinder liners |
| Anti-foaming property | Foam volume <150ml (ASTM D1881 standard) | Bubbles cause poor heat dissipation |
| compatibility | Can be mixed with original antifreeze (same type) | chemical reaction produces precipitation |
3. Performance comparison of mainstream brands in 2023
Combining e-commerce platform sales and user reviews, the following popular antifreeze data is compiled:
| brand | model | freezing point | Reference price (yuan/4L) | User rating (5-point scale) |
|---|---|---|---|---|
| Shell | Diesel Extended Life | -37℃ | 168 | 4.8 |
| Mobil | Delvac Extended Life | -45℃ | 198 | 4.7 |
| Great Wall | FD-2E | -35℃ | 95 | 4.5 |
| Castrol | ES Compleat | -40℃ | 185 | 4.6 |
4. Precautions for use
1.Do not mix different colors of antifreeze: Mixing ethylene glycol (green) and propylene glycol (red) will produce a colloidal precipitate;
2.Clean thoroughly when replacing: Remaining old liquid will reduce the performance of the new liquid. It is recommended to rinse it twice with distilled water;
3.Check concentration regularly: Use a refractometer to check, and the concentration needs to be kept between 40% and 60%;
4.Storage requirements: Unopened products should be kept away from direct sunlight. After opening, they should be sealed and used within 6 months.
5. Expert advice
The winter maintenance guide recently released by the China Construction Machinery Industry Association emphasizes:"Antifreeze with a freezing point of -35°C and lower is more suitable for excavators in northern areas, and special models for heavy machinery must be selected.". For excavators working under high loads, it is recommended to check the antifreeze status every 800-1000 hours.
Through the above structured data analysis, I believe you can choose antifreeze for your excavator more scientifically. If you want to know more about the actual measurement data of specific models, you can pay attention to our subsequent in-depth evaluation reports.
