If you insist on 0w20 ,Amsoil SS, Redline, Mobil 1 AP or EP. I think one or both of the Mobil choices is API certified. On the looks of the car I'm personally disappointed in what Honda did with the butt end of it. It's like they didn't know what to do with the rear bumper and put those black honeycomb pieces of cheap looking plastic. The other 3/4 of the vehicle is good looking. They should have deleted those plastic cutouts. Sorry bud. Jmo...
