Where the hell are you getting this information from??

So you can compare a 5 to 30 viscosity

But you can’t compare an oil that flows like a 5 VS the one that flows like a 30?

Is that what you are seriously trying to tell me? Are you nuts?

It’s the same thing.

A 5 gets a rating because it flows like a 5 AKA X speed and you record the temp.

You measure another oil and you get that it flows like a 30, record the temp.

You take a multigrade and freeze it, flows at same rate as a 5.

You warm it, flows like a 30.

But you’re saying I cant compare the speed of it cold VS the speed of it warm?
