I asked this not to interchange these two fluids.
Thank you for your clarification. So you mean the only way we can compare the thickness of the oil is by using the viscosity index (VI)?
One more extra question.
If the oil viscosity (cSt) at 40°C is 34 -36 range and has a higher viscosity...
Hi,
I'm new to this forum. I have a question on the lubricant viscosity index and Viscosity (cSt) at 40°C.
Can we identify the oil thickness or thinness by comparing only the Viscosity (cSt) at 40°C? Without checking the viscosity index (VI)?
Some oils have a lower Viscosity (cSt) at 40°C...
