Where are you getting these "compression" figures?

I stand by my original post, in a jet engine you compress the fuel
approximately 70 to 1, gas is normally compressed 14 to 1. To use avgas
except in a emergency can burn up the combustion chambers and burn the
turbine wheels severely. You can not feed them on a regular basis.
