I use 5w-30, which is what I believe the owners manual calls for. There is a temperature chart which shows which oil is best suited for different temperature ranges in the owners manual. IMO, 10W-30 is too thick for todays tight engine tolerances. I only use 10W-30 on my older, high mileage vehicles. Welcome to the forum!
Edit: I use 5W-30, not 5W-20.
