$53 is less than $170 though you may have to invest a little time. DIY and save some dollars. These are the products I use on my wife's '16 so your mileage may vary.
Castrol Edge 0W-20 for $17.42 is a good price

Okay thanks! Could you possibly provide the Amazon link? I found two listings, one for five quarts and another for 6 quarts which is massively more expensive.
