Yes definitely a thing but not really in this country. If you live somewhere cold it’s important as is winter diesel, pre-heating etc etc.

Yep the ?W is it winter viscosity the other figure is viscosity at 100c

But often manufacturers will recommend a different grade for cold whether so say 10w40 here but winter in Alaska a 0w40
