1. Core indicators of loader hydraulic oil
According to ISO international standards and industry practices, loader hydraulic oil needs to meet the following key performance requirements:
| Performance parameters | Standard requirements | Typical value range |
|---|---|---|
| Viscosity grade (40℃) | ISO VG 46/68 | 41.4-50.6 cSt(VG46)/61.2-74.8 cSt(VG68) |
| pour point | ≤-15℃ | -20℃ to -30℃ |
| flash point | ≥200℃ | 220-260℃ |
| Anti-wear properties | Comply with DENISON HF-0 standard | FZG test≥level 10 |
2. Comparison of mainstream hydraulic oil brands in 2023
Based on recent e-commerce platform sales data and user reviews, the following popular products have been sorted out:
| brand | Model | Applicable temperature | Price range (yuan/18L) | User rating (5-point scale) |
|---|---|---|---|---|
