Many people are going to have many different opinions on this. Where are you located and what is the typical temperature range?

API SM OR SN rated. Lower 1st number oil will flow quicker to engine parts than higher 1st number oil when motor is below normal operating temp. 0W30 is the same vis as straight 30 when at normal operating temp. 0W30 is a lighter vis (flows quicker) than straight 30 when motor is below operating temp.
