2006 FORD GT engine oil

4. Open the engine compartment cover. Protect yourself from engine
heat.
5. Locate and carefully remove the engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert
the indicator fully, then remove it
again.
Check oil level within 1 minute of
shutting off the vehicle.
•If the oil level is between the MIN—MAX marks, the oil level is
acceptable. DO NOT ADD OIL.
• If the oil level is below the MIN mark, add enough oil to raise the level
within the MIN—MAX range.
• 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
oil in 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
Use SAE 5W-50 full synthetic engine oil.
To protect your engine’s warranty use Motorcraft SAE 5W-50 full
synthetic or an equivalent 5W-50 full synthetic oil meeting Ford
specification WSS-M2C931–A. SAE 5W-50 full synthetic oil provides
durability performance meeting all requirements for your
vehicle’s engine .
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the scheduled maintenance guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

ENGINE COOLANT
Checking engine/intercooler coolant
The concentration and level of engine/intercooler coolant should be
checked at the mileage intervals listed in theScheduled Maintenance
Guide . The coolant concentration should be maintained at 50/50 coolant
and distilled water, which equates to a freeze point of -34°F (-36°C).
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 bottom of the lower
baffle in the coolant reservoir. If the level falls below, add coolant per the
instructions in the Adding engine coolant section.
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 -34°F (-36°C).
• Boiling protection up to 265°F (129°C).
• Protection against rust and other forms of corrosion.
• Enables calibrated gauges to work properly.

Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.
Driving style — good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
• Steady speeds without stopping will usually give the best fuel
economy.
• Idling for long periods of time (greater than one minute) may waste
fuel.
• 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 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
• Revving the engine before turning it off may reduce fuel economy.
• Using the air conditioner or defroster 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 to Lubricant specificationsin
this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in the scheduled maintenance guide chapter.

The PCV valve is a critical emission component. It is one of the items
listed in the Scheduled Maintenance Guide chapter and is essential to
the life and performance of your vehicle and to its emissions system.
For PCV valve replacement, see your dealer or a qualified service
technician. Refer to the Scheduled Maintenance Guide chapter for the
appropriate intervals for changing the PCV valve.
Replace the PCV valve with one that meets Ford material and
design specifications for your vehicle, such as a Motorcraft or
equivalent replacement part. The customer warranty may be void
for any damage to the emissions system if such a PCV valve is not
used.
2For spark plug replacement, see your dealer or a qualified service
technician. Refer to the Scheduled Maintenance Guide chapter for the
appropriate intervals for changing the spark plugs.
Replace the spark plugs with ones that meet Ford material and
design specifications for your vehicle, such as Motorcraft or
equivalent replacement parts. The customer warranty may be
void for any damage to the engine if such spark plugs are not
used.
