If you use Zerex coolant you'll have full blown AIDs within 2-3 days. HIV within a week from the BMW coolant.

The only safe mixture is grain alcohol and rain water. There's fluoride in everything else.

(Either is fine. Dilute 50/50 with distilled water.)

IIRC, the Xerex is not diluted. But that discussion was a long time ago.

If you're talking about the color of Zerex G-05, that's actually one of the main reasons I ended up buying the BMW coolant. That, and they were the same price.

Always. If you think there's tap water in it now, you should do a flush. I would use the cheapest green coolant with distilled water before using The World's Best Coolant with tap water.

Yes. It's like $1/gallon at the grocery store.

Not sure who keeps saying G-05 is the same as BMW coolant, it is similar but not the same. If you want the exact coolant buy Zerex G-48 or Pentosin NF. Those are the only direct replacements, otherwise you might as well just flush everything out and go with something else.

Good luck finding Zerex G-48.

Here in northern california most Napa stores carry G-48, or at least can order it if not in stock. It's only $18

Are you sure? It's not available anywhere online. I've never seen it in a store. It's not on the Valvoline/Zerex website.

I've seen it on the NAPA website, but you can't purchase it online. If you can get G-48 for $18 there's no reason to buy anything else.

EDIT: I say that because the G-48 is slightly better for aluminum protection than G-05. They're quite similar, and I wouldn't be too concerned about using one over the other. They have their differences, and they're clearly different enough that the G-48 is specified by most euro carmakers.

Heres the PDF for Zerex G-48: http://content.valvoline.com/pdf/zerex_g48.pdf

Napa website: https://www.napaonline.com/napa/en/p/ZRX861583/

I just bought a gallon at my local Napa in Sacramento a few months ago, I just checked their website and it's available in other stores too. The valvoline technical document even has BMW approval. If you can pick it up/order at Napa locally, definitely do it!

Next time I buy coolant (which will be soon) I'll definitely check with NAPA first.

I've seen the Valvoline/Zerex PDF before, but it's not listed on any part of their US website. You have to Google it to find it. And it's on their Australian page.

The G-05 was $27 here at NAPA, so I just bought the OE BMW for $24 from the dealership. I doubt it would be $18, but at least now I have some hope that NAPA can order it. I'll post on the forum when I find out. Thanks for the info.

The easiest answer is just buy the Genuine BMW blue undiluted coolant and mix it with distilled water. It's like $20, and needs to be changed every other year.

IMO it's not worth the time to investigate alternatives to maybe save $5 once every other year.

Agree, but for the people who don't have a BMW dealer nearby but have a Napa, Zerex G-48 is a direct replacement. In fact G-48 is BMW blue.

All the euro blue coolants are G-48. Mercedes, Volvo, BMW, etc.

Has anyone else seen it at Napa?
