What oils/grease to use

[classiclife]

Hello Steve,

I had a look at the Motul website and also noted the BS6580 reference:
https://www.motul.com/ch/en/products/au ... assic-25-c

It certainly gives the impression that the product is suitable and of note it states the following "four seasons, based on monoethylene glycol, using non-organic additives" in addition it is already mixed to -25C capability.

To assist and x-reference, I have attached this link covering Granville Sub Zero Blue AF - again it refers to BS6580 : 2010.
https://granvilleoil.com/techData/pdfTechData?ptdID=138

It will be prudent to contact both companies and ask their advice - especially Motul as that is going to be one of your likely purchases; along with Granville to confirm the guidelines pertaining to BS6580.

Both of these products are based on the MEG, which is the critical element.

I hope the above is of assistance.

Regards.

Richard.

Steve,

You will find that BS 6580 is the same as AFNOR R-15-601 which you will certainly find at your local French Autoshop.

It is strange that we have not got an EN spec for it. Probably lobbying from Audi / VW / BMW etc to let them sell their overpriced "own spec" stuff!!

Thanks for your replies. I haven’t had the time to pursue this yet, but I’ll post up if I find a definitive answer.
