As you compare different specifications of oils (https://online.lubrizol.com/relperftool/pc.html), the differences on the scale sometimes look to be significant...but are they really? How do you know just how different some specs really are.
I ask because if the grades on the scale are very close, then two different specs appear to be very different but, in reality, they may not be much different at all?
Hopefully my question makes sense. Can somebody clarify this for me?
Thank you,
Ed
