Rather than start a new thread, I thought I would ask here.

I'm trying to locally source an appropriate coolant. I ordered OEM coolant from FCP, but they failed to ship it and won't be able to get it to me by tomorrow. I found locally Pentosin and Zerex coolants which claim to be compatible. Are these compatible with a partial change, or only if I change out all fluid?

The Zerex is G48 premix @ $20/gal, which I will be buying 2gal to be safe
The Pentosin PF-NF-1.5L would come out slightly cheaper since it appears to be undiluted.

Of course the BMW brand I originally purchased was cheaper than either of these, go figure. It will be arriving Monday and FCP has already agreed to refund me without a return, since it was 2x their mess-up that cost me the fluid.

The Zerex G48 I have doesn't seem to be a premix. It has pretty much the same directions as the BMW one that I also have. Zerex/Valvoline is also the OEM brand (not Pentosin).

The only one I can find states prediluted.

G48 is fully compatible with what is already present from the dealer?

Yes, it's the same coolant. I got mine from rmeuropean.com and it is a concentrate (see link below). Apparently there is also a 50/50 mix being sold in local stores (for more $).
