Dear list, For reasons not germane to this discussion, I just purchased some 15+ liters /16 quarts of Iveco approved antifreeze for my engine. It comes in 1 liter, 3 liter, a 8-9 liter jug, and then in a metal tin. I paid about $43.50 for the 15-16 liters / quarts. It is supposed to be thinned with no less than 25% water and no more than 50%. This is the first year I have been able to find the actual named brand of the antifreeze, and not just a brand that claims to meet the mil-specs that Iveco states. It is made in Turkey from EU import chemicals, but further research indicates that no one knows of a Turkish brand made in country that they would be willing to use. So, my wonder is did I get hood-winked? Too late to return but can buy locally produced ones (with U chemicals) that are maybe 40-50% cheaper but do not allow for more than 25% dilution.

And yes, I use distilled water for dilution. Since I only do this every 4-5 years, seems like doing it right is the right thing to do. Lee
