Picked up some Valvoline Premium Blue on sale. Plan to use it obviously in summer but what would be a conservatively safe low temp for cranking in a gas engine that specifies 5w/10w?
15w40 safe temperature?

I think the temperature range on 15w40 is +4F to122F. I use 10w40 in my vehicles and maybe a handful of times every few years will have to start in temps as low as negative single digits. In Dec. 1989 the temps dropped to near -30F if I remember correctly, the engine turned over a bit slow but my car started at those temps with 10w40.
Depends on the car, and how powerful the starter is and how good the battery is.
According to J300 a 15W40 oil would be tested at -20C (-4F) for cold cranking. Often the battery is the weak link here.
If I recall correctly you drive long periods of time without shutting the engine down? In that case a 15w40 would be a strong performer above freezing. And still suitable to Lower than that
Yup. There's always one cold start of the day though.
Above or below 0F ?
Maybe it specifies 5W and 10W oils because you're in north america where 15W only are HDEO oils. Check if other grades are recommended overseas for cars that have the same engine as yours.
I have started my JD Tractor at 14-18*F with 15W40 ( Maxlife this past year), without issues or plugging it in.
I don't know which part of Mass you live in, but I live in Western MA. It's usually a bit warmer as you get towards Boston and the South Shore (Shoah).
I have to ask you guys: Why the Abuse? We love our Kia's and take care of them.......LOL

Class 8 Diesel trucks can start OK down to about 0F. Below that they need to be plugged into the block heater. We used the block heater below 32F just to take the strain off the starter and battery.
Yea, they will start but they aren't happy!
EDIT: And a little either!

They are all the way to 20w50 in Australia.
Ha. I love my little Hyundai and take care of it too, I just drive it hard.
Just for fun here's the temperature chart for the RHD uk/Australia manual (mine is the GDI 1.6L).
It stems back to a friends 800 dollar 2002 Elantra The Hyundai’s I have personally owned I try my best to take care of
