Stuff like this is why I'm so ga-ga for 0W30 oils these days. Even if we don't often put the low-temperature specs (-35°C, yow) to the test, they'll flow much better after cold-weather starts than 5W_ and 10W_ oils. Just imagine what that chart would look like if extended to include some
real cold temperatures.
