Key specs
| Spec | Value | Method |
|---|---|---|
| KV40 | 1000 cSt | ASTM D445 |
| KV100 | 55.3 cSt | ASTM D445 |
| Viscosity index | 106 | ASTM D2270 |
| Pour point | -22 °C | ASTM D97 |
| Flash point | 273 °C | ASTM D92 |
| Density at 15 °C | 0.899 g/cm³ | typical |
Grade checks
- KV40 is inside ISO VG 1000 (900–1100 cSt).
- Computed viscosity index is 106, within 2 points of the listed 106.
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.
Classification
- Category: Gear
- Attribute: Anti-Wear, Extreme Pressure

- AGMA class: AS
- FZG fail stage: >=14
- Copper: 1B
- Note: Extreme pressure gear lubricant
Sulfur, EP additives and yellow metal
Extreme-pressure gear oils use sulfur compounds so steel teeth do not weld under shock. That same sulfur can tarnish or pit copper, brass and bronze: a bronze worm wheel, a brass cage, a cooler tube. ASTM D130 sits a polished copper strip in the oil and scores the colour. 1A and 1B are the ratings to keep when yellow metal shares the oil. The strip below is that test at room temperature.

Questions
Is Chevron Meropa 1000 an ISO VG 1000 oil?
Yes. The catalogue lists it as ISO VG 1000, which is a kinematic viscosity of 1000 cSt at 40 °C, plus or minus 10 percent (900 to 1100 cSt). Confirm the current data sheet before you fill a machine.
What is a Chevron Meropa 1000 equivalent?
Published oils in the same application and grade include Castrol Molub-Alloy GM 300s/1000, Shell Omala S2 GX 1000. 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 Meropa 1000 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.
