In extremely cold weather, some diesel engine operators will mix small

assisting the more reluctant gasoline to burn as a result of
compression.

thats done to keep the diesel from turning into jello at low
temperatures. the cars i had could take up to 30% gas for that in the
winter.

Certainly; but consider that you were limited to that 30%. If you
exceeded 30%, you risked damaging the engine because the mixture would
be too volatile, (rather than not volatile enough), right?

if you go over 30% it would run too hot (so i was told) and it would
ingite too early like you say.

But the reason you add gas is NOT to make it burn better but to keep it
from freezing.
