Key specs
| Spec | Value | Method |
|---|---|---|
| KV40 | 46 cSt | ASTM D445 |
| KV100 | 8.19 cSt | ASTM D445 |
| Viscosity index | 152 | ASTM D2270 |
| Pour point | -48 °C | ASTM D97 |
| Flash point | 216 °C | ASTM D92 |
| Density at 15 °C | 0.875 g/cm³ | typical |
Grade checks
- KV40 is inside ISO VG 46 (41.4–50.6 cSt).
- Computed viscosity index is 153, within 2 points of the listed 152.
Viscosity and temperature
ASTM D341 (Walther) fitted to the published KV40 and KV100. It is an interpolation between those two points, and it is not meaningful below the pour point. Move the control to read a temperature.
Classification
- Category: Hydraulic
- Attribute: Anti-Wear, R&O

Questions
Is Mobil Univis 46 an ISO VG 46 oil?
Yes. The catalogue lists it as ISO VG 46, which is a kinematic viscosity of 46 cSt at 40 °C, plus or minus 10 percent (41.4 to 50.6 cSt). Confirm the current data sheet before you fill a machine.
What is a Mobil Univis 46 equivalent?
Published oils in the same application and grade include Chevron Rando HDZ 46, Castrol Dual Range HV 46, Shell Tellus S2 VX 46. The match is from typical data-sheet values, not from an OEM approval. It is not an exact equivalent. Confirm the substitute with the machine builder.
Can Mobil Univis 46 be mixed with another oil?
Mixing two oils that share a base family is sometimes done and sometimes a mistake. Do not mix this oil with a PAG. For any other mix, follow the maker's change-over guidance and the machine manual.
