What is the best antifreeze to use in the Tiger?
Halfords tech team recommend Silicate for pre 1998 cars, but I've read differing reports about it and would like some feedback please.
Or is it best to stick with the old tried and tested Bluecol.

Since March 2012 I have used Fernox Alphi II that is used in central heating systems. see link - http://digital.turn-page.com/i/14172/3
