Running Out Of Fuel; Fuel Economy - Lincoln 1997 Town Car Owner's Manual

Running Out of Fuel

NOTE: Avoid running out of fuel because this
situation may have an adverse effect on modern
powertrain components.
You may need to crank the engine several times
before the fuel system starts to pump fuel from the
tank to the engine.
If the engine does not start, check the fuel pump
shut-off switch and reset as required. See Fuel
pump shut-off switch in the Index.
WARNING
Never pour fuel in the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in fire and personal injury.

Fuel Economy

Fuel economy is an estimate of the efficiency of
your vehicle and can be calculated as Miles Per
Gallon (MPG) or Liters Per 100 Kilometers
(L/100K).
Do not calculate fuel economy during your vehicle's
break-in period. This would not be an accurate
estimate of how much fuel your vehicle will
normally use.
To calculate fuel economy:
1. Fill the tank completely and record the initial
odometer reading.
2. Every time you buy fuel record the amount (in
gallons or liters) purchased.
3. After at least three to five tankfuls, fill the fuel
tank and record the final odometer reading.
4. Use these equations to calculate your fuel
economy.
