't
Running-in
The importance
of
correct running-in
cannot
be
over-
emphasised for during
the first few
thousand miles
of
motoring,
particularly the first
thousand,
all working
surfaces
of
the
vehicle,
including
clutch
and
brakes
are "bedding-in"
and
the eventual
performance
of the vehicle is
affected
by the
care
it
receives
during
its
early
life.
Most important,
avoid the
use of full throttle,
particularly
at
low
road speeds
and
when the
engine is
cold.
Running-in
should
be progressive
and no harm
will
result from
allowing
the
engine
to "rev" fairly
fast
for
short
periods
provided
that it is
thoroughly
warm
and not
pulling hard.
Use up to about half-throttle
initially
and select
a
lower
gear
as necessary to
avoid
overloading
the
engine.
As
the
engine
becomes
increasingly
responsive,
wider throttle
openings
can
be used, but the
engine
should
not be subjected to full
throttle
in
any gear, until at least
1,000 miles
(1,600
km),
have
been
covered and even then, full
throttle
should be
used only for
short
periods
which may
be
graduallyextended
as
running-inprogresses.
Maximum Engine
Speeds
Owners
are advised not
to drive the
car at engine
speeds over
5,500
r.p.ffi.,
indicated
by the beginning
of
the red
segment on the
tachometer,
and to
avoid over-revVing,
particularly in
the
lower
gears.
Recommended
Fuel
The
"TR6"
engine
is designed
to operate on fuels having
a
minimum
octane rating
of
100
(5
star*)
(Research
Method).
it(100
octane fuel) Equivalent
to
British
Standard
(5
star)
rating.
Overdrive
Unit
(when
fitted)
An
overdrive
unit
serves as
a
convenient method
of providing,
at will,
a
numerically
lower
overall
gear
ratio to reduce
engine
speed and wear,
and to effect fuel
economy.
Greatest benefit
will
accrue
from
judicious
use of the over-
drive, the
governing
factor being that the
vehicle continues to run
easily without sign
of engine laboring,
combined
with the mini-
mum
amount
of throttle opening
necessary to maintain
this
condition.
Do
not change
from
overdrive at engine
speeds
in
excess of
4,000
r.p.m. This
corresponds approximately
with
peak revs.
in normal gears.
Damage
can
result from overdrive disengage-
ment
at
higher
engine
speed.
