Points To Watch When Running Car In

There are a number of minor points m connection with running a car, which, if given attention as occasion demands^ 'may well make a material difference m an owner's yearly maintenance bill. '

•THE most important concerns, the 1 treatment of a new car, and the less expensive the car, the greater the need for care. Upon the way it is treated during the first few months of running largely depends the measure of its reliability and length of life. In no circumstances should a new engine be over-speeded, and it is important to remember that this is a matter of piston speed rather than of car speed. Owners, particularly of the cheaper models, which manufacturers cannot afford to run-in properly before delivery, are advised by the makers not to drive over 20 to 25 miles an hour during the first 500 miles run. The wise man will strictly adhere to this injunction. t - He will be still wiser if he bears m mind the fact that the principle applies equally to speed on the lower gears. It is useless to keep down to 20 miles an hour on top if a tight engine is run up to 15 or 16 miles fairly frequently on second or third speed. Moreover, much patience and care will we wasted if, after the first 500 miles, the maximum is not raised progressively. : Most chassis, even of the expensive type, are better driven with a good .reserve at all times during the first 1000 to 1500 miles. A point applicable throughout an

engine's life which bears materially on durability is that of starting up and running an engine from cold. The life of all machinery is dependent, not only upon the quantity of lubricant supplied as a cushioner or insulator, but also upon the quality. Oil loses its vitality with use. ■ . : Thus it is important and economical to clean the back axle, gearbox, and especially the engine from time to time, and replenish them with fresh The power developed by an engine is largely dependent upon the correct setting of the sparking plug points and the tappets. For this reason .clearances not be neglected, but should be examined arid corrected periodically. Do not neglect the maker's instructions as to chassis lubrication. The road wheel bearings— parts which are generally forgotten.— should receive due attention. Covers would last half as long again if kept at the correct pressure andL if small stones which have become embedded m the tread are picked out before they have time to work through to the foundation. For the preservation of varnished coachwork a copious supply of water should be employed m washing, and the use of petrol or paraffin should be avoided.
