whats it used for
i was told last year 10ml per 10l so that would be 400ml
Here's a chart to show the freezing point of isopropanol in water. I reckon you would need ten percent for a normal english winter. So that's six and a half litres for a 650l tank?www.engineeringtoolbox.com/ispropanol-water-d_988.html
So how much do you experts need in your tank to prevent freezing?
Nor mine last year (0%) Not my charts either. If that chart is right then you are all wasting your money i would think - no?
what is everyone paying and where you get it from??
