■ML NUMBER of care are now equipped with-engines capable of an engine speed of from 2000 to £6OO revolutions per minute—some over. _ To realise the meaning of this new, demand on lubrication, we must know what 2600 r.p.m. means. Every sacond the mngneto must furnish 21 individual sparks in each cylinder ; 21 times -per second the temperature, at time of ignition, reaches from 2000° to 3000° F. In an engine having, for instance, a bore of 3}in. and stroke of 4%in., during each second, each piston travels over a surface equal to about 27 square feet. If the combined heats of comDustion and friction were permitted to continue unchecked, the cylinders would soon be a mass of molten metal.Destructive friction-heat must be prevented. The burden falls sharply on a thin film of lubricating oil—seldom over .003 of an inch thick. If the oil is of poor quality t)"<» «"« fll™ danger of breaking down. We instance a rather severe test that was made quite recently:— A tractor pulling 6500 pounds on drag was driven for 30 minutes through mud ten inches deep. With a supposedly good oil the water in the radiator reached boiling point in 17 minutes. On "replacing this oil with the correct grade of Gargoyle Mobiloils, the boiling point, under the same operating conditions, was not reached until 27 minutes passed by. This plainly indicates better lubrication and a marked reduction of friction heat. Note the grade of Gargoyle Mobiloils specified for your car in the accompanying chart.
