Grade checks
- KV40 is inside ISO VG 32 (28.8–35.2 cSt).
- Computed viscosity index is 96, 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 Castrol Hyspin AWS 32 an ISO VG 32 oil?
Yes. The catalogue lists it as ISO VG 32, which is a kinematic viscosity of 32 cSt at 40 °C, plus or minus 10 percent (28.8 to 35.2 cSt). Confirm the current data sheet before you fill a machine.
What is a Castrol Hyspin AWS 32 equivalent?
Published oils in the same application and grade include Mobil DTE 24, Shell Tellus S2 M 32, Chevron Hydraulic Oil AW 32. 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 Castrol Hyspin AWS 32 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.
