So 5w30 with k&n would be fine all year around..

The viscosity of a lubricant is closely related to its ability to reduce friction. Generally, you want the thinnest liquid/oil which still forces the two moving surfaces apart. If the lubricant is too thick, it will require a lot of energy to move the surfaces (such as in honey); if it is too thin, the surfaces will rub and friction will increase. The viscosity of liquids decreases as temperature increases.

So in warmer climates like in the south or in the summer time you want to run 10w 30 motor oil as it has a higher viscosity..but you will reach a higher temp thresh hold and the oil will "thin" out enough to still lubricate. Cooler temps like the north or winter you want to run a more thin viscosity oil as temp thresh holds are not as high.
