Questions
Is Chevron Cylinder Oil W 680 an ISO VG 680 oil?
Yes. The catalogue lists it as ISO VG 680, which is a kinematic viscosity of 680 cSt at 40 °C, plus or minus 10 percent (612 to 748 cSt). Confirm the current data sheet before you fill a machine.
What is a Chevron Cylinder Oil W 680 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 Cylinder Oil W 680 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.
