Also, pressure enables a slightly higher boiling point, if you put it under pressure [which it should be] then the boiling points could easily be 10° higher. No matter what the mix if it ever boils then you are overheating and problem is not the mix but somewhere else.
You took the words right outta my mouth!! Stop doing that!! LOL
