2021 FORD MUSTANG oil level

Ford
’s first use of the Mach 1 name came
on a concept vehicle – a wheel-less
single-seat pod tethered to an arm that
allowed it to glide on a cushion of air
around a circular track set up at the Ford
Rotunda in the spring of 1959. Ford ’s
Levacar Mach 1 Concept was an
air-propulsion flying car of sorts,
suggesting that vehicles in the future could
use ducted air to levitate and maneuver at
high speed while off the ground.
The Mach 1 name was resurrected in 1966
for another Ford concept car that was
meant to preview some aerodynamic and
styling advances for a futuristic
high-performance Mustang fastback. The
two-seat Mustang Mach 1 Concept that
was shown at the 1967 Detroit Auto Show
featured a slanted areo-grille, severely
chopped roof, large air scoops and steeply
slanted rear glass as part of a full
hatchback -- a design feature that
wouldn ’t appear in production until 1974.
Ford updated the Mustang Mach 1 Concept
with a new front-end treatment in time for
touring the auto show circuit in 1968 to
herald the popular pony car ’s third styling
refresh due the following year.
By the time 1969 had rolled around, the
again restyled and upsized Ford Mustang
was facing a series of new challenges, both
in the muscle car wars taking place out in
the marketplace by an onslaught of
powerful new competitors, and inside of
Ford Motor Company, where a new, Steed
for Every Need marketing approach
expanded pony car offerings to five distinct
models with at least 10 different
powertrain combinations. Ford's Mustang
had galloped into its fifth model year
refreshed with unmistakable good looks,
thanks to its 2+2 fastback now called the
SportsRoof, featuring upper rear-quarters
cut with forward-facing scoops and a
dramatic tail that incorporated an upswept
rear edge. Even though the GT equipment group
introduced in 1965 was again available for
a final year, it was overshadowed for 1969,
as the hot ticket was an all-new Mach 1
model – wearing the name borrowed from
those radical recent Mustang show cars.
The new Mustang Mach 1 came standard
with the 351, a desirable mix of appearance
enhancements, plus special reflective
bodyside stripes and an uplevel interior.
Later, a flat-black rear decklid spoiler and
a set of rear window louvers were added
as dress-up options. To many enthusiasts
today, a ’
69 Mach 1 equipped with an
optional new-for-’ 69 428 Cobra Jet V-8 is
the first true Mustang muscle car and a
top-shelf collectible.
Other than yet another front-end
freshening (including going back to just
two headlamps and adding non-functional
outboard air inlets) and the elimination of
the side scoops, the biggest change to the
1970 Mustang lineup was a move to the
Cleveland-design 351 V-8 over the Windsor
351 version from the year before. The GT
model was dropped in the face of the
Mach 1's popularity, but the 428CJ engine
option was again available across the
board. By 1971, Ford ’s famed
first-generation pony car had already
undergone its fourth major facelift, growing
in every dimension to accommodate even
bigger engines. The ’ 71 Mustang featured
an extended nose with a body that was
wider, close to a foot longer and around
600 pounds heavier than the original. The
SportsRoof-only Mach 1 model was now
Ford's bread-and-butter enthusiast model,
especially with the optional new big-block
429 Cobra Jet engine, good for 370
horsepower.
There were only minor changes on tap for
Mustang in 1972 and ’ 73, most of them
dealing with the options list and the
continuing emasculation of engine
offerings and horsepower in the face of
emissions and fuel economy regulations,

as well as the elimination of a convertible.
The automotive performance world soon
came to a screeching halt in the wake of
an oil embargo and resulting gas
shortages, forcing most Americans to
abandon their muscle cars and
V-8-powered rides in favor of smaller,
more fuel-efficient vehicles. Ford saw the
market shift as the perfect time to return
its pony car to its roots – a compact,
affordable, sporty car whose styling and
image captured the spirit and imagination
of the American public.
When the new-from-the-ground-up,
second-generation Mustang II was
launched for the 1974 model year, it was
the first Mustang equipped with a
four-cylinder engine. An all-new 2.3-liter
I-4 produced around 90 horses as the
standard powerplant for the downsized
Mustang II - yet performance was roughly
equivalent to the previous Mustang’
s big
inline six. The Mustang II was available as
a hardtop two-door notchback coupe or a
three-door hatchback-style fastback.
Buyers had a choice of either I-4 or V-6
power, as well as a three-speed automatic
or four-speed manual transmissions. To
keep Mustang’ s performance image going
even in a world where consumers favored
fuel economy over horsepower, an
enthusiast-focused Mustang II Mach 1
model was offered as a three-door
hatchback-style fastback, replete with
bucket seats.
There ’s little question that the saving grace
for the Mustang II’ s performance
reputation came when Ford finally realized
it needed to put the 302 V-8 back onto the
Mustang option list for 1975-78. The V-8
was available in any model, but first only
mated to a three-speed automatic
transmission, as a four-speed manual was
delayed a full year until a suitable clutch
could be tooled up. The two-barrel 302
shoehorned into the Mustang II got
catalytic converters to help meet 1976 ’s tighter emissions standards, and saw an
increase to 139 horsepower – nearly equal
to the ’
73’s standard V-8 power level. The
Mach 1’ s optional Competition Suspension
package offered stiffer springs, adjustable
shock absorbers and fatter front and rear
stabilizer bars to improve handling, and
kept it a popular enthusiast choice over all
five years of Mustang II's production. By
the dawn of the third-generation Mustang,
the Mach name would not return again to
the Mustang line until some 25 years later.
After the 1979-93 Fox Body Mustang years
had come and gone with the reintroduction
of a GT model, new sheet metal on a
revamped SN-95 platform helped to
rekindle consumer interest in a
fourth-generation Ford Mustang.
Enthusiasts lavished their attention upon
the 1993-1999 Mustang Cobra
performance model developed by the Ford
Special Vehicle Team skunkworks group,
while Ford engineers looked to specialty
models to fill the mid-market slot between
the standard Mustang GT and the
upmarket Cobra.
After the success of the 2001 Bullitt, a
new-for-2003 Mach 1 was launched to
offer fans some design cues from its '69
namesake, including a blackout hood,
black front air-dam extension and rear
decklid spoiler – even bodyside scoops. To
match its aggressive look and hardware
upgrades, the '03 Mach 1 was powered by
a 305-horsepower, 4.6L DOHC modular
V-8. Unlike the SVT Cobra, the Mach 1
offered an automatic transmission option
in lieu of the manual, and consequently
drew a new group of enthusiast buyers into
the Ford fold. The strong customer
response prompted another year of Mach
1 production for 2004, the Mustang's final
year on the fourth-gen platform.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors can result in
reduced engine power and the illumination
of the service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design. The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
•
Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• Fuel system leaks, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
• 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, see your authorized
dealer as soon as possible.

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 90).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 264).
5. Have your vehicle checked as soon as possible. Reduced Vehicle Top Speed
Your vehicle's ability to reach and maintain
top speed is partially dependent upon
ambient temperature. Under certain
environmental conditions, your vehicle's
top speed may be reduced to protect
powertrain components.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back
home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
There are also some things you may want
to avoid doing because they reduce your
fuel economy:
• Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
