FIVE OIL MISTAKES How to stop maintenance pounds from blowing through the exhaust MOTORISTS are looking for scientific ways to reduce upkeep. Old mistakes—always costly—to-day positively extravagant —must go. Here are five common lubrication errors. They are responsible for many of the operating troubles that motorists experience. MISTAKE No. 1 £ " Oil is a good thing—you can't have too much of it." Some motorists believe that if the oil reservoir is filled above the indicated high level, V r—-x better lubrication will be provided. They'are.mistnken. Oil should be kept at the proper aL. ’ C tS: level—no higher. Over-filling causes excessive carbon, gummed valve stems and sooty spark-plugs. MISTAKE No. 2 "I use heavier oil because my engine’s badly uorn." 'I Many motorists believe that a change to heavier oil is advisable in a worn engine. This is not so. Worn engines need overhauling. Heavier oil is no substitute for worn parts. The lubrication system of a car may be wholly unsuited to properly distribute a heavier oil than specified in our Chart of Recommendations. . MISTAKE No. 3 "Old oil never does any harm in the crank-case." Some motorists neglect to dr in the old oil from the crank-cases of their engines nt ' sXvsKMto" 11'1 frequent intervals. The correct oil is not destroyed in use. But it does become contaminated with B r * l drawn in through the breather, with carbon particles from the undersides of the pistons and with water condensation. It also becomes thinned out with fuel absorbed ■AJ = ' V' 3C by the oil film on the cylinder walls, especially when the mixture is too rich. For these reasons old oil should be drained from the crank-case frequently. ■ MISTAKE No. 4 " When refilling I always clean out my engine crank-case with kerosene." fi This procedure sounds logical—hence has come into common use. Experience ehows, however, that it is almost always a mistake, for some of the kerosene is usually 7 iTT retained in the splash troughs or other oil pockets in most crank-cases and thus thins out "A. the new °‘b T he better plan is to drain the crank-case when the engine is hot. This will /7 carry off the sediment before it settles. Then flush out with a quart of fresh oil and refill 'K f s to the correct level. // MISTAKE No. 5 S"My oil seems to work all right." " /.Ci This, perhaps, is the grandfather of all lubrication mistakes, “My oil seems to work all right ” sends more cars to the repair shop than all other causes combined. The motorist cannot watch from day to day the inside of his engine. Hence he is in no position to knolv accurately the effects of different oils. While many oils may “ seem ' to work all right,” only one of those oils may be giving him scientific lubrication. , And V only that one can give him—the lowest fuel bills, the lowest oil bills and the lowest repair nw bniB ' The Chart of Recommendations specifies the grade of Gargoyle M Mobiloils which is scientifically correct for your car. a The use of that oil and the avoidance of the common mistakes mentioned here will show you engine results—economy and power—which you may — never have had before.
