Yep. The CCS always seems to be the W grade's limiting factor. Often it looks like the boarder line pumping would pass at least a grade lower.Also a good example of how a relatively low pour point doesn’t always result in a superior winter rating. It still would not be desirable for starting below 0F.
A little head room and extra layer of protection is always a good thing. If the engine starts, the oil better pump.
