Mercedes coolant, which is re-labelled Valvoline Zerex G-05.
This is really getting confusing... now there's G-40 for Mercedes and Porsche.
I'm thinking about trying this in the future, if for no other reason it has color. When I see a puddle under the car I always wonder if it's AC condensation or leaking G-05.
Great.......it makes you wonder if this is really superior to previous coolants or some compromise to appease the environmental lobbyists.
I think the important rule's still apply. Change on regular intervals and don't mix different coolants. Aside from that, make sure whatever you are using is rated for aluminum engines.
Now Zerex comes up with G-40 for Porsche and Mercedes? We can get Pink, Green, Brown & Clear antifreeze... What happened to standardized colors for automotive fluids???
Why can we have multiple colors of anti-freeze but only one color of brake fluid? I miss super gold/blue, it made bleeding our brakes, clutch and PSD so much easier!
Sorry to go all off topic, but this is kind of crazy!

Yeah I miss being able to easily flush the system with the ATE Gold/Blue as well. Made life a bunch simpler.
I cannot hep but ask what kind of results are you looking for? Unfortunately any negative reviews of a coolant won't be known for several years and even then, not until the engine is taken apart to see corrosion and the assumption it wouldn't have happened with a different coolant.
It's really a crap shoot at this point.
I did send an e-mail to Valvoline about this. I've received very quick and detailed responses from them in the past about motor oil so we shall see.
Anyone found a good Coolant Tester that works w/ the OAT (G-05) coolants, most of them do not.
Would be looking for Freeze levels and Acidic test, now I just Flush and refill with the 50/50 mix.
