The link Plumb Bob posted said that oil MUST be marketed as the lowest grade it meets. So in theory, any 0w should be thinner at -35 than any 5w.
(That's my understanding. Thoughts?)
But, I haven't yet seen if there is any way to compare them at the same temp. IE its -20 here tonight, are the...
Okay. I get it now. The winter grade isnt a set temperature, but rather a maximum thickness at each temp level.
That makes more sense. So simply the 5w30 isnt below 6,200@-35 and therefore must be a 5w.
It definitely makes sense now.
I was just trying to see how much thicker the 5w30 i use...
Hey all. Im new here, long story short, I was looking at reducing the amount of oils I buy, and was looking at the difference between the 5w30 and 0w20 that I use.
Am I missing something, or is the 5w30 CCS viscosity not lower than the 0w20? Why is that?
Thanks in advance, I'm not really sure...
