IMPORTANT
HE attention of owners of new
M,,. Midget Sports cars is
drawn to the following.
The importance of carefully
running-in a new engine cannot
be over-estimated, and care and
restraint during the first 2,000
miles will
be handsomely repaid.
Change the engine oil after the
first 500 miles, and every 1,000-
1,500 miles thereafter.

M.G. Midget
(Long Chassis)
The first thing that the owner will want to know concerning his Car will
be the various lubricants that are rcconlmendcd
hy the maker:, and the points
of the chassis that require attention. The engine oil filler is situated on the
off side of the engine alongside which there is
a dip stick. Under no circum-
stances should the Car be driven fast on the lower gears or exceeding
35 miles
an hour on top gear during the first
500 miles. At the end of this period the
engine oil should be drained and the base chamber refilled uith new oil. The
oil filter which will be referred to later should be removed and washed out
with petrol, this should be again attended to :liter the first
1,000 miles and
cvery suhsequent
1,000 miles.
It is inadvisable to run a cold engine fast until the oil has had an
opportunity of circulating and warming up sufficiently in order to circulate
freely through the oil passage ways throughout the engine. The pump is
called upon to suck from the base chamber or sump oil which has become
thick with standing, particularly in cold weather. It may he noticed that
the oil gauge will show that the pressure drops
:IS the speed increases if the
engine is driven at all fast when cold. This is an indication that the oil has
not become sufficiently thin to pass into the punip in sufficient quantity. The
pump lubricates the whole of the engine including the valve gear.
