Grade checks
- KV40 is inside ISO VG 320 (288–352 cSt).
- Computed viscosity index is 97, within 2 points of the listed 98.
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 Clarity Machine Oil 320 an ISO VG 320 oil?
Yes. The catalogue lists it as ISO VG 320, which is a kinematic viscosity of 320 cSt at 40 °C, plus or minus 10 percent (288 to 352 cSt). Confirm the current data sheet before you fill a machine.
What is a Chevron Clarity Machine Oil 320 equivalent?
Published oils in the same application and grade include Mobil Teresstic 320. 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 Chevron Clarity Machine Oil 320 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.
