Grade checks
- KV40 is inside ISO VG 100 (90–110 cSt).
- Computed viscosity index is 98, 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 Mobil DTE 27 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 Mobil DTE 27 equivalent?
Published oils in the same application and grade include Shell Tellus S2 M 100, Shell Tellus S2 MX 100, Castrol Hyspin AWS 100. 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 DTE 27 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.
