Great care should be exercised in mixing oils at all, and it is far preferable, i f
anybody wishes t o run on a particular oil o r is so forced by circumstances, that
the old oil should be drained o u t first and a complete replenishment made.
Under no circumstances should paraffin be used t o wash o u t the lubricating
system unless the engine is being dismantled.
More detailed instructions o f t h e
lubricating system o f the engine will be found on pages
48
and 51, which deal w i t h
the complete travel of the oil f r o m the sump t o the pump, thence through the
various pipes and passages i n the engine t o the main and big-end bearings and t o
the overhead valve gear. The oil pump is provided w i t h a relief valve o f very
simple construction consisting of a spring and dash-pot enclosed i n a cover plug.
The details o f this will also be found on page 50.
W e w i l l now leave the general lubrication summary w i t h the advice t o use
only recommended oils whenever obtainable. Keep the receptacle that is used
for filling clean and covered, and also wash round back axle and gearbox filler caps
before these are unscrewed. The gearbox and back axle should be refilled
for preference after the car has been running some time, so that the
lubricant has had a chance t o become fluid.
