I can't get this to work, keep getting a gateway error. It worked great a couple weeks ago. Anyone know the new address?

The problem is with Shell. It doesn't even work via the Shell link here

I've got that same link from one of Pablo's posts; it's all his fault.

Anybody find the link working yet? I use this infrequently and can't find it anymore.

Here's another one … vi calculator

If all you want is the blended viscosity, it's the antilog of the weighted means of the logs of the viscosity of each oil in the mix. If you want to calc VI, then you need more that I don't know the equation for.
