Gents, ok I might me onto something here and don't want to get too excited at this stage but let's see.
So I have been doing some research on the Nissal LLC antifreeze that everyone likes and hates at the same time because of the high price.
I actually did track down the company who produces the antifreeze and they are called "Unico Manufacturing" and are based in Durban.
The downside is that they produce ONLY for the vehicle manufacturer and don't sell to other companies/the public.
But another option that is worth looking at is that this specific antifreeze is called Glysantin G48
and is actually produced by allot of other brands of antifreeze in other countries. Another interesting fact is that Mercedes, BMW and a couple of other manufacturers use this exact same antifreeze and are cheaper.
I just bought 10 bottles of the BMW one for R100/L which is already a bit better and will do some more research and compare the two to double check if they are really the same. I am also looing for other brands that sell the G48 spec antifreeze so lets see where this goes.
