Show Useful Oil Gauge Will Prevent Injury to Car " The oil gauge Is one of the most Important instruments on an automobile. automo-bile. The presence of the oil gauge on an instrument board, plus the driver's understanding of it, can prevent damage dam-age to the car. The oil gauge, an engineering bulletin bulle-tin says, is the only Indicator the driver lias to tell if something goes wrong with the oil supply. If the oil does not circulate, or If there Is no oil, the gauge will register zero. Starting with a cold engine the oil Is heavy, and although the gauge Indicates In-dicates a high pressure, very little oil flows through the bearings to be sprayed on the cylinder walls. That is the time to drive carefully and at a moderate speed and not abuse the engine. As the engine warms up a reduction in oil pressure will be not iced as the oil flows freely through the bearings and the operating parts are properly lubricated. Every type engine has its own average aver-age operating pressure, which the motorist should learn from his instruction in-struction manual. Any change from this pressure, except higher pressure when the engine is cold, should be Investigated In-vestigated at once. Extreme low pressure pres-sure reading might indicate loose bearings, loose connections in oil line, lack of oil, or oil thinned by dilution. The function of the oil gauge Is to tell If the engine's oiling system is working. It does not, of course, indicate indi-cate the quantity of oil in the crank-case crank-case or condition of the oil filter, the latter a device through which the oil is filtered and kept clean and which should be. periodically serviced. |
