i live in san francisco CA now maybe it will get to 45F on a cold day? 15w40 all yr long is not a big deal
but i do plan to go to tahoe where it will be actually cold so i'm switching over to a 0w30 at the end of november
when i lived in NJ i used 5w30 oil in the winter and avoided high rpm/full boost situations for extended periods of time
