Grade checks
- KV40 is inside ISO VG 68 (61.2–74.8 cSt).
- Computed viscosity index is 182, within 2 points of the listed 183.
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 Shell Naturelle S2 68 an ISO VG 68 oil?
Yes. The catalogue lists it as ISO VG 68, which is a kinematic viscosity of 68 cSt at 40 °C, plus or minus 10 percent (61.2 to 74.8 cSt). Confirm the current data sheet before you fill a machine.
What is a Shell Naturelle S2 68 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 S2 68 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.
