You can change the rate at which APU fuel is consumed in your
Config\XR5VaguardPrefs.cfg file:
Code:
#--------------------------------------------------------------------------
# APU Fuel Burn Rate : this is the rate at which APU fuel is burned in kg/sec.
# The Auxiliary Power Unit (APU) provides hydraulic power to the ship.
# 0 = unlimited : (runs indefinitely)
# 1 = very low : 20.1 kg/minute (44 lb/minute) (3.7 hours runtime)
# 2 = low : 40.3 kg/minute (89 lb/minute) (110 minutes runtime)
# 3 = moderate : 60.4 kg/minute (133 lb/minute) (74 minutes runtime)
# 4 = realistic : 90.6 kg/minute (200 lb/minute) (49 minutes runtime)
# 5 = expert : 135.9 kg/minute (300 lb/minute) (33 minutes runtime)
#
# The default value is 2 (low: 110 minutes runtime).
#--------------------------------------------------------------------------
APUFuelBurnRate=2
It's more fun to
conserve fuel by turning off the APU when you don't need it (just click the bright red APU button or press CTRL-A), but if you'd rather increase the runtime, just set
APUFuelBurnRate=1 or
APUFuelBurnRate=0 in your preference file.

APU Fuel Management on page 35 of the XR5 Vanguard Flight Operations Manual.
