starter. Under these conditions the clutch pedal may be depressed when operating
the starter, to relieve the motor of the considerable drag in the gearbox. Intelligent
use of the starter, as described, will greatly prolong the life of the battery.
It is also advisable to add 1 ½ % of engine oil to the fuel in very cold weather. This
is at the rate of quarter of a pint of oil to each two gallons of fuel. However, this
practice should not be continued excepting under these very cold conditions. The
addition of oil to the petrol will improve the lubrication of the cylinder bores, which
is desirable when the engine is working in exceptionally cold weather.
Starting with Engine warm or hot
When restarting the engine while it is still hot the accelerator pedal should be
depressed to about one third of its travel before pulling the starter control. If
difficulty is experienced in starting, due to the use of the choke device when the
engine is hot, the mixture may be momentarily too rich, in which case depress the
accelerator to the full extent whilst operating the starter with the choke control
pushed right in.
Warming up
In order to minimise cylinder wear the engine should be warmed up quickly, when
starting from cold in winter, the engine may be "idled" for a minute to let the oil
circulate but it should not be allowed to idle for long periods, neither should the
engine be raced up to high speeds.
To accomplish rapid warming up, the engine should not be started from cold until it
is desired to drive the car away. After starting, the choke control should be pushed
back to the half-way position. A speed of approx. 30 m.p.h. in top gear may be
regarded as a desirable warming up speed. Do not forget to push the control right in
as soon as the engine will allow, and do not give full throttle until the engine has
warmed up. An automatic thermostat is fitted in the cooling system, incorporating a
by-pass, which greatly assists in quick warming up.
