A point which many drivers fail to realise is that the full benefits derived from running- not with care are in a new car made manifest until it has covered At this stage 10,000 miles or 80, an engine which has been treated) carelessly will be commencing to give trouble in various directions, notably by consuming more oil than seema reasonable, while one which was driven with circumspection carly in its life will be running as well as ever. Furthermore, there is usually quite a big difference in the smoothness and quietness with which an engine runs after 10,000 miles, according to whether or not it was treated properly at the be- ginning.
During the process of running- in, what actually happens fa that all the working surfaces gradually become polished to a mirror-like finish, tiny excrescences left when they were machined being rubbed. off one against the other.

be The reason that care must taken when driving a new car is -effects that until these various upon the bearing surfaces are pro- duced their atliness renders them particularly susceptible to damage from overloading or overapeeding. A little thought will show clearly that the amount of heat generated in a stiff bearing depends both upon the load pressing the surfaces at which together and the speed rubbing takes place.
Simple Instruction for
Handling New Cars.
Bearing these points in mind, it]
is quite easy to deduce the rules which should govorn a driver when handling a brand-new car. In the first place, he must at all costs limit, his
a reasonable speed to figure; for most cars this will be, at first, 30 m..p.h. on top and, per hups, 20 m.p.h. on the next indirect ile must also avoid full- throttle hilleilmbing; for example, if a fairly steep gradient is being tackled it is better to climb it at 15-20 m.p.h., on "third," using half throttle, than at a similar speed on "top" using full throttle with the engine labouring heavily.
gear.
As the mileage increases it is permissible gradually to augment the load imposed upon the engine; indeed, if one does not do so, run- ning-in may take an interminable time. Thus, after 250 miles or so one can raise the top gear speed to 86 m.p.h. and can indulge in ocensional bursts up to 40 m.ph. Even higher speeds will do no harm so long as they are not maintained for more than, say, half-a-minute at a time. This gradual increnso in loading can be carried on as the miles build up, the alm being that eventually, when a distance of 1,000 miles has been covered, the car is capable of being ved quite freely. It will be seen that this pro- cedure forms a sharp contrast to the erroneous method so often the owner in which pursued Berupulously avoids exceeding 20 m.p.h. for 500 miles and then suddenly commences to use his car as though it were fully run in.1
