Anti freeze has 5 main additives.
1 anti corrosion.
2 water pump seal oil.
3 water wetter sufficant.
4 anti cavation.
5 anti scale water softener.
Also dye and of course ethylene glycol.
50% water and glycol antifreeze has a specific gravity of 1.06 to 1.09.
Maximum is 70% antifreeze.
I was told about the anti cavation additive today. I didn't know.
Methanol antifreeze is not sold in the UK now.
