LUBRICATION.

IMPORTANCE TO ENGINE. The efficiency of an automobile engine and the duration of its usefulness depends so much upon proper lubrication that motorists to-day recognise the importance of good lubrication even if they know very little about the variety and quality of oils. As for the choosing of oils, the type of lubrication best suited for any particular motor is usually recommended by the manufacturer or dealer.

Recently models have been so improved that the consmuption of oil is comparatively small. An automobile owner can usually afl'o i\ to pay the price to have the best oil for his car. High-priced oils are not necessarily the best, but a motorist should not accept an inferior grade simply because of a high first cost. Motor lubrication systems have been brought 'nearer to perfection in the development of the oil filter. This apparatus removes from the oil the metal particles worn off operating parts, and takes out any dirt which might collect through careless filling or in other ways get into the machinery.

Thc filter also takes care of hard particles of carbon which drop from the .underside of ,tho piston by absorbing them. The dirt can be taken out of the filter and after extended use the filter can be replaced. The pressure feed system of engine lubrication is another improvement. Its development has greatly increased the efficiency of the engine. To develop its greatest usefulness the engine must be run at a high rate of speed. When this is done the pressure on the bearings is great enough to force out the film of oil and allow the metal parts to come in direct contact with one another. Under forced lubrication pressure is maintained on the oil in the bearings, aiding the oil in holding the surfaces apart. As long as the surfaces are kept there can be no wear.
