Zerex???

[urban_legend]

I looked for Mike Focke's and others recommendation for Zerex Extended Life 5/150. Closest I could come up with is:
Zerex G-05 (phosphate free) 5/150.
Approved for Benz & BMW all years.
And Porsche/Audi up to 1996 - they they recommend Zerex Dex-Cool.
Oh and it is pink - for what that is worth.

Before I pore it in - looking for advice.

Advice: Buy the OEM stuff, it is only about $20 a gallon (you will need two to do a complete change) and mix it with distilled water only.

Considering that this OEM stuff is readily available, not all that expensive, I fail to see why people keep trying to use something else..........but, in the end, it is your car and the resulting problems will be yours as well……….

Plus, you only need to do this every 5 years... so if you break it down to per year cost it's not that bad?

Paying Porsche a ridiculous amount of money for their coolant is fine if you don't trust what you read on the internet. But then I'm not sure why you'd be on the internet. There's no risk to using a like-formulated coolant at half the price of what the dealer charges. It's kind of like sticking with Mobile 1.

According to toolpants, even the manufacturers know of equivalents.

G 05 is not compatible.

The G-05 stuff is likely a better formulation than the others, and a lot of BMW guys (myself included) are running it with good success, but I'm not sure I'm ready to put it in the Porsche. I've been using the Havoline Dex-Cool in the Porsche.

There are two ways of looking at this. Considering how infrequently one swaps coolant, and how little the car takes, it's really a wash in overall cost to not just spring for the factory stuff. On the other hand, why pay over twice the price for the factory stuff, when equally good alternatives are available?

Honestly, I think that where all the coolants have gone in terms of development, you could probably buy the absolute cheapest, Walmart branded stuff and as long as you made sure (via a good flush) that you weren't mixing coolants, you would be just fine. I don't think you can even buy a coolant anymore that isn't Phosphate free.

I paid $25 for the Porsche coolant, and it's actually 2 gallons since it's a 50/50 mix with distilled water. That's $50 to replace all your coolant, without any guesswork as to what may or may not work, every 5 years. It may not be the best, but I know it works and if something goes wrong the dealer can't say, "Oh, well thats not Porsche coolant, so it's not our problem."

The only real issue we see are the over heated cars flat bedded in with oatmeal-like glop where the coolant should be. Because of the resulting mess, and the time to clean it out, a coolant change that should cost $300-400 ends up costing a couple grand in time and materials......... So, yeah, feel very safe buying something that is a few bucks cheaper, you will definitely sleep better at night knowing you saved a few bucks...........

And as for "sticking with Mobil 1", well I won't even go there............

I honestly have no clue what you're saying here.
