ENGINE OIL SYSTEM (Cont)
ENGINE OIL LEVEL AND REPLENISHMENT SYSTEM
The engine oil servicing doors are located on the forward and left side of each engine nacelle. Oil quantity may be checked
by a sight gage on the AGB and replenished through the oil filler port. The gage bands are marked FULL, ONE LOW, and
NO DISPATCH. However, the primary means to check oil on the Challenger 300 is with the Remote Oil Level Sensor
(ROLS). Oil levels are transmitted by the ARINC 429 bus to the refuel/defuel panel located in the right wing root fairing.
Wait at least 15 minutes, but not more than 1 hour following engine shutdown before checking the oil using ROLS, and
service the tank if more than one quart (0.95 liter) low. Each engine oil tank capacity is 7.8 quarts (7.4 liters), while the oil
volume at the FULL mark is 5.7 quarts (5.4 liters). The ONE LOW band indicates when the tank is approximately 1 quart
below FULL. The NO DISPATCH band is approximately 1.6 quarts below FULL. If the oil level is
below this band, the
tank should be serviced prior to dispatch. However, if the oil level is within the band, the engine can be operated at least
10 hours without servicing the tank. The 10 hour time frame assumes a maximum engine oil consumption rate. Note that
the oil volume is less than the total tank volume of 7.8 quarts (7.4 liters). The total tank volume design accounts for hot oil
volume expansion and for the additional volume between the sight gage FULL mark and the fill-to-spill level.
NOTE: The oil level indication lights on the refuel defuel panel are for reference only. If the CHECK OIL light on the
refuel defuel panel is illuminated, visually check the oil tank sight glass for dispatch ability.
