When cold, 5w20 acts like SAE 5 oil. As it heats up (typically rated at 100° Celsius), it acts like SAE 20 oil.
Yes, and a 20 weight oil at 200F is thinner than a 5 weight oil at 70F.

chill out man, all I asked is why, as in why would you? r-e-l-a-x
Using 5W-30 instead of 5W-20 may help quiet down any ticking the Coyote is known for. Plus, if the car is ran hard, the 5W-30 will not thin down as much and help provide a little more protection at high oil temps.

Here in tropical Philippines, official Ford country distributor only allows 5W-30 or 5W-40 to be put into the car. And the dealers all use Shell Helix Ultra AF fully synthetic.

Instead of creating a new topic I'll just add on to this one since there's a lot of information here. I am going into my first oil change in about a week, I don't drive the car a lot, I've had it 2 months about and have only 1,300 miles. It IS my only car and is my daily driver. I try to let it warm up in the mornings when it's cold (I live in west Kentucky by the river) and temps get as low as single digits. I would say I let my car warm up adequately 80% of the time. I also drive this thing like the beast it was built to be on the roads. What oil weight do you all recommend for me and why?

Why are you changing it so soon?

The best way to warm up a car is to drive it moderately until it is up to temp. Letting it sit and idle slows down the warm up process and increases wear.

OP, I think you would be OK with that weight in Alabama. I have a big concern about cold oil pressure. Mine runs 90psi with 50 degree oil until it warms up. I am afraid to go with a thicker oil for that reason. Don't put much stock in what was done in 11-14 coyotes as the heads were redesigned in 15. I am told that is why the 5W-50 called for on 11-14 track packs is not called for on 15-16 PP.
