I use blue antifreeze in all three of my cars all the year round and have done so for many years. Blue (ethylene glycol based) antifreeze should be changed every two years. As I understand matters (and no doubt there will be someone on the forum who is more technically savvy than me) the antifreeze contains corrosion inhibitors that 'go off' presumably because they inhibit corrosion by chemical reaction.
It is because of the corrosion inhibiting properties, especially given the delicate state of many Austin Seven blocks and the studs that hold the water manifolds in place that I use it on a permanent basis, changing it, as I hvae said at least once every two years.
