For the US market M3/M4s, LM recommends only SPECIAL TEC B FE 5W-30.

I would stick with the stock oil.
Where did you hear LM only recommends the 5W-30 weight for the Special Tec B FE for US markets? The Special Tec B FE also comes in 0W-30 weight and according to their oil selector recommendation both are acceptable.
