Viscosity Calculations?

[apon004]

I have a liquid with a viscosity of 460 cP @ 20 degC, the question that I have is how can I calculate the viscosity of this liquid at different temperature for example at 80 degC or 120 degC. I tried to look for a viscosity vs. temp. graph but I wasn't able to find anything. In advance thanks for your help.

I don't think you can get anything with just one datapoint.

Yes, you need either:
2 datapoints
or
viscosity index and one datapoint
