2017 Honda MT fluid 5W-30 Amsoil
Doublecheck before you change. I just did my 2018 Civic Hatch Sport 1.5 Turbo 180 HP. I used Amsoil 5W-30 (MTFQT-EA). The Amsoil site indicates that this oil is backwards compatible to Honda OEM fluid. After 1,000 miles I noted the smoother shifting everyone raves about. This is a very light fluid compared to a 75/90W gear oil.
