'Possibly footage from 1936 Winter Olympics in Germany. Cross country skiers riding over wood bridge through snowy forest; VS skier riding down hill. Great LS ski jumper in tuck position skiing down long steep ramp of jump; cut to ski jumper flying through the air; LS ski jumper lands jump, camera pans over to audience in bleachers, Nazi flag with swastika insignia hangs by bleachers. Two men on sleds dive head first down track away from camera; VS people riding on sleds; VS of the luges racing through luge course. Great shot sailboat-like sled glides over camera on ice; VS men sledding on sailboat-like sleds; VS ice skating; high-angle pair figure skating. CU ice, blade of figure skate slides up to camera; camera zooms into CU blade of ice skate against ice; CU figure skate blade against ice with superimposed arrows to aid in audio tracks explanation of the physics of ice skating. CU figure skate with moving projection background to make skate appear as though it is gliding over the ice. Boy about 12 slides down slide into pool; formally dressed men women and children on Coney Island ride with boat sliding to shoot into water. CU disembodied arm opens filing cabinet drawer then takes bar of soap and soaps edge of drawer then opens and closes the filing cabinet door. Great shot of the disembarking of a huge late 1930s ocean liner, audience watches as ship enters water. CU scientist for an experiment pours oil for lubrication from a metal kettle onto small ramp then releases a black from top of ramp letting it slide to the bottom. Train engineer lubricating various parts of train. CU disembodied hand dabs finger tip in glass container filled with oil; CU disembodied forefinger with oil on it is pinched together with the thumb; VS scientist does experiment with flywheel bearing and various methods of lubrication. CU of an engine, cover of engine dissolves from shot revealing cross-section of an engine exposing pumping cylinders; VS graphic illustrations of a running engine and the pathway of oil through the engines various parts. Camera zooms in on cross-section of running engine to main bearings, superimposed arrows in shot identify the bearings next to the crank shaft; cut to cartoon illustrating the main bearing receiving oil in a running engine. CU cross-section of a running engine, camera zooms in on the cam shaft; CU valves opening and closing; cartoon of cross-section of running engine. CU running engine; CU oil being poured into gears; VS cartoon of running engine and the locations where oil enters the system. Great shot old locomotive producing large black cloud of smoke heads toward camera alongside tracks; train speeds by camera, "New York Central" painted on side of train. Great shot two men, one greasy mechanic and one filmmaker behind movie camera filming with a stroboscope a running engine; CU SLO MO of oil dripping around spinning crank shaft of engine; cartoon animation shows cross section of running engine with pumping cylinder. Scientist wearing a long white lab coat holds a hose attached to an engine; scientist turns on nozzle of hose and sprays oil from the engine onto a blank blackboard; CU disembodied hand holding hose spraying oil in a somewhat phallic gesture; CU oil spraying on board. VS CU various running engine parts, superimposed over various CU shots is a shot of oil slowly dripping from top to bottom of frame.' Public domain film from the Library of Congress Prelinger Archive, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Motor_oil ...Motor oils are derived from petroleum-based and non-petroleum-synthesized chemical compounds. Motor oils today are mainly blended by using base oils composed of hydrocarbons, polyalphaolefins (PAO), and polyinternal olefins (PIO), thus organic compounds consisting entirely of carbon and hydrogen. The base oils of some high-performance motor oils however contain up to 20% by weight of esters... Lubricating oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them, decreasing heat caused by friction and reducing wear, thus protecting the engine...
