I don't think the Military had active duty piston engine aircrafts in
the 1980s. It was all GA.

One thing to consider is old frieght dogs changing from piston
powered beasts to turbine monsters. A Twin Beech or DC-3 burns
quite a bit of fuel.

One stat I've seen, but can't source right now, is that $bignum
percent of piston engines could run on a 95UL fuel (basically a
super premium blend of mogas), but the majority of avgas burnt goes
into the $smallnum percent of engines that can't burn 95UL and need
100 octane. I wonder if that stat is still true, with there being
a lot less big piston aircraft out there now.
