Thanks-i'm still confused though. This webiste

https://www.wolflubes.com/EN_EU/Blog...d-coolant.aspx

says G11 was introduced in 1994, and also says that G13 is not good for copper/brass radiators and lead solder.
I want ot buy a 20 litre drum of the stuff, and also use it in my 1970 Spitfire. Am i going to cause myself problems?

I just can't get my head round these things. I will certainly do a flush through of my MB system, so this will be all new coolant in the system and I like the idea of G13 which can mix with anything, in case i get stuck some time in the future, but will G13 be OK with the standardradiator?

Thanks again..

PS
this is the sort of thing that gets on my nerves:

https://www.ebay.co.uk/itm/MANNOL-20...7fb99f7cd90412

its claimed to be "G13+" and is yellow. But what is G13+ (plus??), and G13 is purple/violet...

I actually have this in at the moment, having flushed everything else out:

https://www.ebay.co.uk/itm/5L-MANNOL...35422140e15c34

Its called AG13 but is green! As long as i don't mix it with anything else then this is fine, but will I remember in 2 years?
Best to get rid now and start again...
