Key specs
| Spec | Value | Method |
|---|---|---|
| KV40 | 150 cSt | ASTM D445 |
| KV100 | 14.6 cSt | ASTM D445 |
| Viscosity index | 97 | ASTM D2270 |
| Pour point | — | ASTM D97 |
| Flash point | — | ASTM D92 |
| Density at 15 °C | — | typical |
Grade checks
- KV40 is inside ISO VG 150 (135–165 cSt).
- Computed viscosity index is 96, within 2 points of the listed 97.
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 Mobil PM Ashless 150 an ISO VG 150 oil?
Yes. The catalogue lists it as ISO VG 150, which is a kinematic viscosity of 150 cSt at 40 °C, plus or minus 10 percent (135 to 165 cSt). Confirm the current data sheet before you fill a machine.
What is a Mobil PM Ashless 150 equivalent?
Published oils in the same application and grade include Shell Paper Machine S3 M 150, Shell Paper Machine S2 M 150, Chevron Paper Machine Oil Premium 150. 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 Mobil PM Ashless 150 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.
