All is in the title. I will soon have to replace my coolant and what i have is one new jug from one brand and an a remaining opened jug from the previous flush from another brand. Coolant is MB 326.0/BMW GS 9400 blue coolant.

PS : It's been two years/60k km since the last flush, is it beneficial to change it now or should i wait a year or more? For my car it should be changed every two or three years but that recommendation was based on the older amber MB coolant (G05?), i remember that the newer blue coolant is supposed to last longer and has a better additive package. What's your opinion?

glysantin G48 can be mixed with pretty much any coolant made in the last 20 years and is of course backwards compatible with older IAT coolants and early HOATs like G05.

5 year service life

Of course you can mix two different brands of G48 coolants, G48 is G48. Much like asking can you mix Aquafina and Dasani bottled water.
