SAE 5W-20 motor oil is a multiviscosity or " all weather " graded oil that provides a wider temperature range of use , and permits you to drive from one climate extreme to another ( My Quaker State motor oil book sure comes in handy ) On newer vehicles the manufacturer may require you to use a 5W-20 oil in your engine - check your owner's manual (Helpfull)
