And besides, these stunts are "pour point", which was invalidated as applying to cold starting back in the '80s, being replaced with MRV, and specific cooling regimes.
So YES, if you are trying to work out which oil will flow through the filler if you are changing the oil at -37C, choose the 5W40...
but these stunts don't tell you squat about lubrication.
