Grade checks
- KV40 is inside ISO VG 460 (414–506 cSt).
- Computed viscosity index is 94, within 2 points of the listed 95.
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.

Questions
Is Mobil Vacuoline 146 an ISO VG 460 oil?
Yes. The catalogue lists it as ISO VG 460, which is a kinematic viscosity of 460 cSt at 40 °C, plus or minus 10 percent (414 to 506 cSt). Confirm the current data sheet before you fill a machine.
What is a Mobil Vacuoline 146 equivalent?
No other brand in this catalogue clears the equivalents bar for this oil yet (same application, same grade, compatible base oil, and a score of 60 or more). That is not proof that nothing else works. Check the machine manual.
Can Mobil Vacuoline 146 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.
