ITHOUT lubrication your car could run only about 20 to 30 times its own length. Friction would then power. As oil saves power, it follows that one oil will save more power than another. An important question is What oil will eliminate the most stop destructive friction in your motor? Motors differ. mand different oils. We present here, in plain terms, the factors that must be considered. This statement is from a com- pany whose authority on matters of lubrication is unquestioned—the Vacuum Oil Company. Figure 1 represents a type of lubricating oil in common use. It has two serious faults, Different cars de- First, its actual lubricating qualtty is low. A guide to correct Automobile lubrica the letter opposite the car indicates the grade of Gargoyle Mobiloil that should be used. For examp! Explanation: In the schedule. “Gargoyle Mobiloil A,” “Arc cover both pleasure and comm means the Second, its body" or thickness is unsuited to the feed system of the motor it is used on. It cannot feed properly. It cannot protect properly after the friction surfaces are reached. Figure 2 represents a better, but still far from perfect oil, It has good lubricating quality. But its “body” is unsuited to the feed system of the motor. It cannot properly reach all the friction surfaces. Figure 3 represents an oil whose “body” is suited to the feed requirements of the motor. But its quality is low. Under the heat of service it rapidly loses its power to protect the moving par Tt reaches the friction points but cannot efficiently protect them. 4 Figure 4 represents what your motor really requires—an oil of the highest lubricating quality whose “body” is perfectly suited to the feed sys- tem of your motor. It properly reaches all the friction points, It protects properly after it reaches them. It is a complete lubricant. With such an oil tically your only friction is the friction of oil against metal. rgoyle Mobiloil Arctic.” rcial vehicles unless otherwise noted. You will find this grade of oil indicated, op- posite your car, in the chart printed in part on these pages. The recommendations in the chart were arrived at after a careful motor-analysis of the cars named, The oil's efficiency has been further proven-out by practical demonstrations, If you use an oil of less correct “body,” or of lower lubricating efficiency your motor must pay the penalty. Some of the consequences are pointed out below. Carbon deposit (excepting that due to faulty carburetion and gasoline combustion) is com- monly attributed to the quality of the lubricating oil. Quite as often the fault lies with the oil's “body.” In some motors, a light-bodied oil will work too freely past the piston rings, into the combustion chamber. Lubricating oil itself is a hydro-carbon Product. Carbon can never be wholly filtered out. When the oil works freely into the closed com- bustion chamber carbon deposit is bound to oc An unnecessary quantity of the oil is consumed. Ignition trouble, and in time, “knocking” of the motor results. Another common result of faulty lubrication is scored cylinder walls. The scoring is generally caused by the oil's low lubricating quality. Or it may be caused by too-light a “body.” Ia that case the oil fails to carry-through to the end of the piston stroke. The piston rings then rub directly against the walls. In time they break. Scoring and scratching of the cylinders will result. Hissing of the motor follows. For all electric vehicles use Gargoyle Mobiloil A. The reco pun, we. wees: wed, S>>ans seas] Wine pombm>, >Fea>ams.
