in the engine.
Great care should h,e exercised in mixing oils at all, and it is far preferable
if
anybody wishes to run on a particular oil or is so forced by circumstanc,es,
that the old oil should he drained out first and a complete replenishment
made.
IJnder no circumstances should paraffin he used to wash out th'e lubric-
ating system unless the engine is king dismantled.
More detailed instruction
of
the lubricating system of the engine will be found on pages

and

which
deals with the complete travel of the oil from the sump to the pump, thence
through the various pipes and passages in the engine to the main and big
end bearings and to the overhead valve gear. The oil pump is provided with
a relief valve of very simple construction consisting of a spring and dash-pot
~nclosed in a cover plug. 'The details of this will also he found on page

General Survey.
Inlmediately after taking delivery of the crlr
it
is
advisable to become famili:ir with its general mechanical details and in order
lo
assist as much as possible
it
has been thought advisable to give
a
brief
pictorial survey of the chassis.
The view shown in Illustr:~tion No.

is perhaps
n
little unconventional
to some people, but it is the view ohtained by looking at a chassis from ~~nder-
neath. The batteries and petrol tank are not in position, but the ~~nder
shield beneath the gear box and front passenger's compartment can h,e seen.
Certain views taken from below will be described later, more particularjy
the front and rear axles.

I
he engine suspension is three point, the single or front point being
mounted in the centre of the front cross member of the chassis. The nose
piece of the engine is fitted into the cross member by means of a split bearing
into which is fitted
a
ruhhcr hush. This nose piece has two brackets, one on
either side, on to which the radiator is fixed by means of two studs.
