Grade selector
ISO VG by application
Select equipment + operating conditions and we'll recommend the optimal ISO VG grade + equivalent LUBESOLUT product. Algorithm based on DIN 51519 / ISO 3448 + OEM industrial practice.
Select equipment
Once you choose the equipment type and operating conditions, we'll show you the recommended ISO VG grade and the corresponding LUBESOLUT product.
Standard ISO VG grades (ISO 3448)
Each grade allows ±10% of the nominal viscosity at 40 °C. The selector recommends within this table.
| Grade | Nominal (cSt @ 40 °C) | Min | Max |
|---|---|---|---|
| ISO VG 22 | 22 | 19.8 | 24.2 |
| ISO VG 32 | 32 | 28.8 | 35.2 |
| ISO VG 46 | 46 | 41.4 | 50.6 |
| ISO VG 68 | 68 | 61.2 | 74.8 |
| ISO VG 100 | 100 | 90.0 | 110.0 |
| ISO VG 150 | 150 | 135.0 | 165.0 |
| ISO VG 220 | 220 | 198.0 | 242.0 |
| ISO VG 320 | 320 | 288.0 | 352.0 |
| ISO VG 460 | 460 | 414.0 | 506.0 |
| ISO VG 680 | 680 | 612.0 | 748.0 |
| ISO VG 1000 | 1000 | 900.0 | 1100.0 |
| ISO VG 1500 | 1500 | 1350.0 | 1650.0 |
Technical notice: This recommendation is indicative. For final selection, verify:
- OEM manufacturer manual (Klüber, FUCHS, Shell, Mobil, BP, etc.)
- AGMA / DIN / ISO specification if applicable (FZG ≥10 for EP, micropitting, etc.)
- Compatibility with elastomers and seals (NBR, FKM, EPDM)
- Volume and change frequency according to operating hours
