2013 GM 3.6

Ok gonna change it out this weekend. I have on hand; QSUD in 5-20, Valvoline Maxlife HM Blend in 10-30, Amsoil SS 0-20, and Mobil One HM in 10-30. It calls for 5-30 and winter is coming. Would 10-30 be OK? QSUD and Amsoil meet specs but not visco.

Either of the 10w30s will be fine. I'm currently using 10w30 Pennzoil Ultra in my 2012 Impala. I'll be switching to 5w30 Milesyn or NAPA after this.
