trying to decide if i can mix Peak Blue "European" OET coolant in with the factory coolant for my 2012 Volvo S60, which i think might be pentofrost nf. the first has

ethylene glycol
diethylene glycol
water
sodium benzoate
denatonium benzoate

and the second has:

ethylene glycol
2,2'-oxybisethanol
disodium tetraborate pentahydrate

any negative interactions that will mess up my car?
