Use what the manufacturer recommends, they put it in your owners manual because that is what was tested in it and found to be proper. Generally you use a thicker oil in the summer for better protection and a thinner oil in the winter for easier start up. in the manual.

It all depends on the type of vehicle and the climate you live in. Thinner, such as 10w 30 is an adequate oil for most vehicles.
