Grade checks
- KV40 is inside ISO VG 46 (41.4–50.6 cSt).
- Computed viscosity index is 220, within 2 points of the listed 220.
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

Questions
Is Shell Naturelle HF-M 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 Shell Naturelle HF-M 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 Shell Naturelle HF-M 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.
