WARMING-UP ENGINE
Slow Idling Not Advised
A motoring hint that has received wide publicity is that when a cold engine is first started it should bo allowed to idle lor a minute or two so that the cylinders warm up aud the oil circulates fully before the engine has to provide a big power output.
In a sense that advice is accurate, but according to many dependable experts one should avoid allowing the engine to tick over slowly, but should set it to run at say six or eight hundred revolutions a minute. The explanation is that it is most desirable to hasten the circulation of the oil, since it has been found that most cylinder wear takes place just after a cold engine fires. Furthermore, one of the products of combustion in the cylinders is water, and many motorists will have observed that when the ear, is first started steam may bo emitted from the exhaust pipe, or drops of tfater fall from the outlet. That water comes from the cylinders, and unless promptly expelled will combine with the cylinder gates and form catbonic acid, which is known to be very destructive of the metal surfaces.
