What is the right antifreeze for Stag engine

[brian]

I have always used Unipart super oat 2 year antifreeze with no problems. However I find it is now 5year and the suppliers say it is not suitable for classic cars as it can affect the solder on copper/brass joint an a radiator also may cause cavitation on the water pump.
Any suggestions/recommendations what I should use would be gratefully received.

I always use the Blue anti freeze Ethylene Glycole is the one I use the 2 year type. Blucol was the one but not so easy to find in the shops I mix 50/50 then no worries whatever the English weather throws at us in the winter ,it is suitable for alloy heads and it does not harm old engine . I was told it must not have Methanol or Alcohol in it . I am sure others will have their favorites and will tell me if I am wrong. Search the forum there is quite a bit on there.

Cant remember the make but it is blue, comes from Europarts and is a good price compared to "Haylofts"

I have recently drained, flushed and filled with 4life 10 year coolant. So far it's working extremely well.
