Need coolant advice

2011 Grizz 700 here and so far the only thing I’ve been told about replacing my coolant is that I should put the same color stuff back in that came out. But other than that nothing specific. A search through both the service or owner’s manual gave no coolant info other than capacity. Here’s a comparison of the old and the proposed new…

The stuff on the left, what’s coming out, is a blue-green. I’m second owner and only put about 75 miles on the machine, so I have no idea how old this coolant is.

Stuff on the right is the new coolant the guy at the car shop suggested, and is more of a pure lighter translucent blue. It’s Pentofrost NF, whatever that is. He said it’s what’s recommended for European, including BMWs. Here’s the bottle…

So…
1) have I found the right coolant?
and
2) am I supposed to dilute it? The bottle says it’s ‘full strength.’
