Grade checks
- KV40 is inside ISO VG 460 (414–506 cSt).
- Computed viscosity index is 208 from the stored KV40 and KV100 (ASTM D2270). The listed index is 205, more than 2 points away.
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 Omala S3 A 460 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 Shell Omala S3 A 460 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 Omala S3 A 460 be mixed with mineral oil or PAO?
No. This oil is a PAG (polyalkylene glycol). PAG does not mix with mineral oil or PAO. Drain and flush before changing into it or out of it.
