Are you throwing it in neutral when coasting down hill? Leaving it in gear is the better route because it activates dfco. Idling in neutral when coastin uses fuel in these cars. When approaching lights or stop signs downshift without touching the gas pedal.
My stock 93 lx consistently got 40 mpg highway. That's not at 5000 feet but you still should yield better than low 30s.
