5w-20 would be like Singer Sewing Machine oil

must be an attempt to improve the fuel efficiency of the engine by reducing the drag that a heavier viscosity oil produces but probably adversely reduces the protection it provides

As it's a 5.7 it's got to be a 2005+ WK Grand

The Jeep dealerships are actually ok for most fluids on price, give them a try first. They will also confirm which oils are suitable for the engine.

My V6 VTEC uses 5w20, as does the Prius. It's becoming more common over time here.
