You lucky guys! Our water really is filth!!! Shocking what they do to it IMHO!

And RE Evans NPG+, it seems a bit of a hit and miss and until I\'ve seen some stronger proof then I think I\'ll just stick to low concentrate antifreeze and change it every year or so!

Used only Blucol in engines for yonks. Same 12A engine for last 15 years, no rebuilds but low miles. (However this is a good test for coolant). Changed every 3 years, using a 40% mix coolant to tap water. The posts above are right about tap water being aggressive, but I thought it was mainly dissolved oxygen in "raw water" which corrodes. Hence the change only at 3 year intervals (Or "O" ring changes!). The blucol goes in blue and more importantly comes out clear blue after 3 years. Perhaps I am lucky with my tap water. If in doubt use demineralised water, but Blucol\'s the business in my book
