Engine Oil Recommendations
4.0L V6 Engine
Look for this certification
trademark.
Use SAE 5W-30 engine oil
Only use oils “Certified For Gasoline Engines” by the American
Petroleum Institute (API). An oil with this trademark symbol conforms
to the current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ILSAC), comprised of U.S. and Japanese
automobile manufacturers.
To protect your engine’s warranty use Motorcraft SAE 5W-30 or an
equivalent SAE 5W-30 oil meeting Ford specification WSS-M2C929-A.
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 according to the appropriate schedule listed in
thescheduled maintenance information.
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 with equivalent performance for your engine application.

•Engine Oil Overheat Mode:The(Engine coolant temperature)
indicator will be on. The instrument cluster has no separate oil
temperature indicator.
Along with the
(Engine coolant temperature) indicator, the engine
coolant temperature gauge will read in the Hot (H) area.
Oil overheat can be triggered in severe driving conditions, such as
towing heavy loads over mountainous terrain in extreme hot
temperatures. As oil temperature increases, engine and vehicle speed
will be limited. The transmission will also shift differently.
When the engine oil has cooled, the vehicle will perform normally.
When fail-safe cooling mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. Remember that the engine is capable of completely
shutting down automatically to prevent engine damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait approximately 15 minutes for the engine to
cool.
4. Check the coolant level and replenish if low. Look for coolant leakage
in the engine compartment and under the vehicle.
Never remove the coolant reservoir cap while the engine is
running or hot.
5. Restart the engine and take your vehicle to an authorized dealer.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to an
authorized dealer as soon as possible.
FUEL FILTER
For fuel filter replacement, see your authorized dealer. Refer to
scheduled maintenance informationfor the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized Motorcraft part. The
customer warranty may be void for any damage to the fuel system
if an authorized Motorcraft fuel filter is not used.
