What oil temp are those viscos for?
I am trying to get more information to see if the technique (and therefor the results) should be questioned or not.
(For those watching at home, we know about viscosity calculation validity much below 0C)
Here is what I was alluding to with this post.
This is a PM convo between myself and widman a few months ago. (I have the permission of both parties involved to post this publicly)
Code:
Me: How accurate is your visco calculator from -20C to 100C?
Widman: With most oils it should be accurate until you factor pour point modifiers
Me: Hm OK, how would a PP modifier affect the visco calculator results?
Widman: It flattens out the expected results at low temperatures.
