2003 FORD F150 adding oil

•Oil levels above the MAX mark may cause engine damage. Some oil
must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the normal range, add only certified
engine oil of the recommended viscosity. Remove the engine oil filler cap
and use a funnel to pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
1/4 of a turn until three clicks are heard or until the cap is fully seated.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this certification
trademark.
SAE 5W-20 engine oil is recommended.
Only use oils“Certified For Gasoline Engines”by the American
Petroleum Institute (API). Use Motorcraft or an equivalent oil meeting
Ford specification WSS-M2C153–H.SAE 5W-20 oil provides optimum
fuel economy and durability performance meeting all
requirements for your vehicle’s engine.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Maintenance and Specifications
224

•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36°C (-34°F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060). The level of coolant
should be maintained at the“cold full”of“cold fill range”level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -36°C (-34°F).
•Boiling protection up to 129°C (265°F).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.

•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
