The water in the East where I am is so hard ,I had Ross Kemp turn up to do a documentary on it!

I always use the original blue Paraflu11 mixed 50/50 with deionised water. The cost of this and the small effort in draining and flushing every couple of years seems well worth it for my peace of mind in keeping my older Fiats running well. Ian
