LUBRICATION
AND
MAINTENANCE
SCHEDULE
Reliable
opera
t ion
of all
Ford
vehicles depends
t
o a great extent
on
t
he use of lubrican ts and ser-
vice
component
s which meet Ford
Specifications.
It is possible that
the use of lubricants or service
products which do not meet these
specifications
may cause damage to
important operating mechanisms.
Conditions
under which
vehicles are
driven vary greatly co nsidering the ex-
tremes of temperature,
urban and rural
traffic, paved
and unpaved
roads
and
dry
areas where dust is prevalent.
Operating conditions are
considered
"
norm
al" unless:-
1.
More than 50% of the opera-
tion is stop and go as in city
traffic.
2. The average trip is less than
10
miles.
3. The operation of
the
vehicle
includes long
periods of
idling
such
a3
encountered in taxi and
police
units,
where mileage
is
not
an
ac-
curate
indication
of
the
engine
hours run.
4. The temperature for
periods
of two
months at a
time regularly
range
below 45•F.
5. Dust
conditions
encountered
are more
severe
than those in a
typical suburban area where the
majority of the streets
are
paved.
6.
The vehicle is used for con-
sistent high speed or competition
driving.
Where the conditions are more
severe than
normal, i.e., one or
more of the above conditions
ap-
ply, then the engine oil
and

OIL QUALITY
Use only oils which have been
tested and certified by the maker
as satisfying automobile manufact-
urers specifications for Engine Op-
erating sequence Tests for Service
MS
.
The
Ford

Company
specification covering these tests is
ESE
M2C
I
OI-C
These
tests
are
defined by ASTM committee 02 for
Section G-IV of technical committee
B and are published in the SAE
Handbook.
These
tests cover
oil
characteristics as follows :-
Sequence I -
Low Temperature
Wear.
Prevention -
(Cold Starts)
.
Sequence II -
High Speed -
High Temperature
Wear.

filter should be changed more fre-
quently:-
The following charts list the lub-
ricant specifications and specified
change periods for normal vehicle
operation.
IMPORTANT
The lubricants listed are specified
:for the maximum service periods
approved by Ford Motor Company
of Australia
Limited.
Manufacturers of these products
may advocate service periods in
ex-
cess of those currently recommend-
ed.
We do not propose to comment
on the validity of these claims but
point <>ut that it is mandatory that
the3e products
be
used in Ford ve-
hicles only for the perio<ls current-
ly
!~commended.

OIL FILTER
Use of the ri ght oil filter is also
essential to good engine life and
cperation.
For

it is essential that
only a genuine Ford filter be used
