The owners manual says to use a ( API SG or SH ECII ) period!
Is Kia lost in a time warp?
The manual also has a graph that shows 5/30 to be used from -25 to +35F and 10/30 from -10 to +90F
Guess the Wife cannot drive anylonger when the ambient is above 90 per the owners manual as apparently a 10/40 is not allowed or will void the warranty!!
