2019 FORD MUSTANG oil viscosity

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 209).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.

1 For complete refill of limited slip Ford axles, add 3.28 fl oz (97 ml) of Additive Friction
Modifier XL-3 or equivalent meeting Ford Specification EST-M2C118-A. Ford rear axles
contain a synthetic lubricant that does not require changing unless you submerge the
axle in water.
2 Oil must meet specification WSS-M2C931-C or use SAE 5W-50 oil that meet API SN
requirements.
If you use oil and fluids that do not meet
the defined specification and viscosity
grade, this may lead to:
• Component damage which is not
covered by the vehicle warranty.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced engine performance.
• Reduced fuel economy.
• Degraded brake performance.
We recommend Motorcraft® motor oil for
your vehicle. If Motorcraft® oil is not
available, use motor oils of the
recommended viscosity grade that meet
API SN requirements and display the API
Certification Mark for gasoline engines. An oil with this trademark symbol
conforms to current engine, emission
system protection standards and fuel
economy requirements of ILSAC.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by your vehicle warranty.

Note:
Ford recommends using DOT 4 Low
Viscosity (LV) High Performance Brake Fluid
or equivalent meeting WSS-M6C65-A2. Use
of any fluid other than the recommended
fluid may cause degraded brake
performance and not meet the Ford
performance standards. Keep brake fluid
clean and dry. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage and possible failure. Note:
Automatic transmissions that require
MERCON® LV transmission fluid should
only use MERCON® LV transmission fluid.
The use of any other fluid may cause
transmission damage.
Alternative Engine Oil for
Extremely Cold Climates
To improve engine cold start performance,
we recommend that you use the following
alternative engine oil in extremely cold
climates, where the ambient temperature
reaches -22.0°F (-30°C) or below.
