Grade checks
- KV40 is inside ISO VG 220 (198–242 cSt).
- Computed viscosity index is 98, within 2 points of the listed 96.
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 533 an ISO VG 220 oil?
Yes. The catalogue lists it as ISO VG 220, which is a kinematic viscosity of 220 cSt at 40 °C, plus or minus 10 percent (198 to 242 cSt). Confirm the current data sheet before you fill a machine.
What is a Mobil Vacuoline 533 equivalent?
Published oils in the same application and grade include Castrol Molub-Alloy GM 90/220, Shell Omala S2 GX 220, Shell Omala S2 G 220. 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 Vacuoline 533 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.
