Most people believe that a 5w30 oil is good for cold weather use because it is a 5 weight oil in cold temperatures and a 30 weight oil at high temperatures. On the surface this might seem to make a certain amount of sense.Naturally, a 5 weight oil would flow better than a 30 weight oil.owever, a 5w30 motor oil will be thinner than a 10w30 motor oil when subjected to the same low temperature conditions-because the W number is lower. This is an indication of better cold weather performance. In other words, a 5w30 flows better in cold weather than a 10w30 motor oil will.
