Yes, I have that generic internet information. I was hoping that you had some actual chemistry data.

Thanks.

For the record, this is how G12 (1:1) looks:

It's organic and lowfat!

You might want to take a look at the urls.

BASF has extensive files (most in German) on the Glysantin line.

At the time I posted the summary, I had looked at the detail files.

G 30, G 33, and G 34 were all basically the same products with slight differences in Ph, etc. G 30 is the G 12 replacement, G 34 the DexCool replacement. G 33 is the Peugot/Citroen version.

Ashland (Zerex, Valvoline) licenses the BASF chemistry.

They recommend the DexCool Zerex Extreme Life replacement for BASF G 30 (the G 12 coolant) and BASF G 34, as does BASF in their European aftermarket lineup.

How does the Motul concentrate compare? Any better than Zerex?

I've run across two Motul Concentrates:

Optimal Ultra (AOT Technology)

It's listed as meeting "ASTM D3306/D4985, ** 6580, AFNOR NFR 15-601, SAE J1034. DAIMLER-CHRYSLER MB 325.3, VW G 12, RENAULT TYPE D, MAN 324 SNF, FORD/JAGUAR M97844-D, GM OPEL/SAAB 6277M, PEUGEOT/CITROEN".

That makes it a G 12 / DexCool type coolant.

The other Motul Concentrate:

Inugel Expert Ultra 50

It's listed as meeting "ASTM D3306/D4985, ** 6580, AFNOR NFR 15-601, SAE J1034. DAIMLER-CHRYSLER MB 325.0, CHRYSLER MS-7170, BMW N 600 69.0, VW G 11, MAN 324 NF, PORSCHE G11".

which is the old VW G 11 equivalent.
