if it's cold outside, go with a 20

if it's warm outside, go with a 30

once the oil is up to temp it's a "5" anyway

A very basic way I use to remember the viscosity is like this:
example: 5w-30.
5 is how thin the oil gets which is important for cold weather
30 is how thick the oil gets which is important for protection in hot weather.
