Thumbs up Zerex G-05 Coolant

Hey, folks.

I see lots of discussion and conjecture around the forum about coolant, quite often it's of the "only MB" vs. "I think Zerex is okay". Zerex has a nice little two-page chart on their website, captured, reduced (for BW limits) and attached here, the first page of which suggests two different coolants. (My guess is that two are listed because it's "Daimler-Chrylser" in the graph, so the original is really for the Chrysler half). The second page references their recommendation for MB cars of the G-05 product.

From that I started an e-mail thread with Valvoline (owners of the Zerex brand) in which they state that Zerex G-05 coolant is approved by MBZ for all models.

Given the difference in cost and availability, that leans me towards Zerex, which is handy because hoses and coolant are in the immediate future.

In any event I thought it useful to share this information with my fellow MBZ enthusiasts.

Take care and enjoy the ride,
Greg

Thanks Greg, I've been using G-05 for several years.

MLFUN you mentioned the OEM fluid. Frequently the OEM (original equipment manufacture) and OES (original equipment supplier) are the same company. OE parts as purchased at the Mercedes-Benz parts counter may not be the same as OEM/OES. Manufacturers, such as Mercedes-Benz, change suppliers. The Valvoline literature states that Mercedes-Benz has approved Zerex G-05 for use in Mercedes-Benz vehicles. This is different than simply meeting a manufacturer's spec. Valvoline may be a supplier.

Didn't mean to suggest otherwise.

I just did the post to clarify the issue because I was tired of seeing people say "I think it's okay"; to me, either it is or it isn't. Generally I'm one of those folks who think it inappropriate to run 87 octane in the car designed for 91 or 93, and I'm also one who can't figure out why some are perfectly happy to dump any old synthetic oil in the crankcase, MB spec or otherwise. That said, I have long trusted Valvoline products, so the fact that they say it meets MB specs (just like 0W40 Mobil1 does for oil) is sufficient for me to trust it.

In all honesty, if it was $23 a gallon like the MB-labeled bottle, I'd probably still use Zerex G-05 because of it's greater availability.

And as I always say, one of the great things about owning a car is maintaining it as you see fit, so I won't criticize anyone who uses either in their car. Now for those who use Prestone....

Take care and enjoy the ride,
Greg

The MB fluid comes pre-mixed whereas the Zerex G-05 does not.

When buying the MB fluid, you are essentially paying for 1/2 a jug of water.

I use Zerex G-05 in all my MB's and have for years. It works great, MB approves of it and the price is right.

1) MB Coolant and Zerex G-05 are identical. Valvoline makes it for MBUSA.








MB Coolant Is Not Pre-Mixed.

You can pay $23 for a jug of fancy labeled G-05 MB coolant or $10 for a jug of the exact same stuff G-05 coolant. The choice is yours.

+1 I just refilled using it. If that stuff is premixed they have some nasty water in Montvale, NJ :-)

Regarding the difference in price, my dealer just sold me two gallons for $13.50 apiece. I don't buy my cars new and never have bought one from a dealer, yet this dealer (Rallye Motors) takes care of me and passes a discount to me because I have been a loyal customer.

The decision to buy OEM is a personal one and I agree that maintaining one's vehicle is an extremely personal decision so far be it from me to criticise someone for their decision. I have found however that there is a give and take when it comes to buying OEM. Many times I find M/B prices to be CHEAPER than the price for an equivalent part from the aftermarket. And M/B stands behind their parts. I only buy M/B batteries for example because they are cheaper and have a better guarantee than DieHard or any of the other equivalent suppliers. Again, its a personal decision but I have been treated well by M/B and have not felt I was being price gouged over the long haul.

Mercedes subcontracts OEM consumables. Batteries are/were made by the parent company of Interstate. Hydraulic fluid is by Febi.

From the horse's mouth - MB coolant and Zerex ARE NOT IDENTICAL. Here's a post I just made yesterday on another forum.

Len

I had an e-mail exchange with the tech folks at Valvoline that I thought some of you might be interested in reading. The Zerex G-05 and the Mercedes coolant apparently are not identical, but probably close enough for government work.

ME: Is Zerex G-05 identical to the Mercedes branded coolant that I would buy at a dealership? Also, since it seems like AutoZone no longer carries Zerex G-05, where can I find it in my area?

ZEREX: Yes, the Zerex G-05 is the approved coolant for the Mercedez Benz application. Our biggest supplier for the product is Carquest Auto Parts. Other options include Napa, Auto Zone, Advance, O'Reilly's, & Pep Boys. If these places don't carry the product, please just ask them to order it for you.

ME: Thank you for your reply. Is the Zerex G-05 identical to the Mercedes branded coolant? Earlier this year there was a rebate on the purchase of the Zerex G-05. Are there any plans for a repeat of that promotion in the works?

ZEREX: It is not IDENTICAL, but the Mercedez formulation and Zerex G-05 are 100% compatible. I am not sure about promotions. Please give our hotline a call at 1-800 TEAM VAL and ask for promotions for this information.
