Default G12 Coolant Vs G13 coolant

Picked up some coolant to flush the .1 this weekend and just noticed that my shop gave me G13. Since I'm flushing the entire system, including front radiators, I am hoping that this G13 will be fine. Looks to be updated cooling which is supposed to be better for the environment. Just wondering if a little got mixed with the old stuff, could there be issues?

Autozone had a crazy sale and these 1.5 L Pentofrost E bottles were only $5, instead of $13 or so
Says it's compatible with G12 and G13, Audi/VW/Porsche Mercedes

I will look to see if they still have it on sale. I have a few cars that all use that stuff.

Everything I’ve ever read states that G13 is backwards compatible with G12. You should have no issues.
