|---|---|---|
| KV40 | 96 cSt | ASTM D445 |
| KV100 | 10.1 cSt | ASTM D445 |
| Viscosity index | 92 | ASTM D2270 |
| Pour point | -39 °C | ASTM D97 |
| Flash point | 252 °C | ASTM D92 |
| Density at 15 °C | 0.96 g/cm³ | typical |
Grade checks
- KV40 is inside ISO VG 100 (90–110 cSt).
- Computed viscosity index is 82 from the stored KV40 and KV100 (ASTM D2270). The listed index is 92, 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 Chevron Cetus DE 100 an ISO VG 100 oil?
Yes. The catalogue lists it as ISO VG 100, which is a kinematic viscosity of 100 cSt at 40 °C, plus or minus 10 percent (90 to 110 cSt). Confirm the current data sheet before you fill a machine.
What is a Chevron Cetus DE 100 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 Chevron Cetus DE 100 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.
