Grade checks
- KV40 is inside ISO VG 15 (13.5–16.5 cSt).
- Computed viscosity index is 147, within 2 points of the listed 148.
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 Rando HDZ 15 an ISO VG 15 oil?
Yes. The catalogue lists it as ISO VG 15, which is a kinematic viscosity of 15 cSt at 40 °C, plus or minus 10 percent (13.5 to 16.5 cSt). Confirm the current data sheet before you fill a machine.
What is a Chevron Rando HDZ 15 equivalent?
Published oils in the same application and grade include Shell Tellus S2 VX 15. 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 Rando HDZ 15 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.
