I searched, but I'm still confused.
0w-30
I think its agreed that the 30 is the viscosity measured at 100 degrees C.
Does the 0w refer to the viscosity at 0 degress celcius?
OR
Does it refer to the oil's ability to "pour" or "flow" at cold temps?
Or am I completely wrong?
I've heard both explanations... Please enlighten me.
