THE EVENING STAR, WASHINGTON, D €. WEDNESDAY, AUGUST 11, 1928. striking advance in motor lubrication MOST motorists realize the importance of a film of oil between moving parts of metal. Drivers are reasonably careful to main- tain this lubrication. But there are times—for instance, after the motor has been standing idle—when it has been impossible for several minutes to get a fluid between moving parts. Even the best of the old type oils drain away trom cylinder walls and bearings, leaving areas which are practically dry. Then comes Over three years ugo the development of a new “Standard” Motor Oil was begun.’ A new principle in lubrication was brought to light. To make assurance doubly sure, «Standard” Motor Oil, in which this principle has been embodied, was not put on sale until it had been tested in scores of cars and trucks of the best known maaufacturers. Comparative trials were made in all weathers, on all sorts of roads—same cars, same drivers, same routes, again and again. Lubrication tests showed that «Standard” Motor Qil did not break down under load or high tempera- tures as compared with the leading old-style oils. Better piston seal with <«Standard™ Motor Oil led to an increase of 3% to 10% in power. Hill-climbing tests proved this. Gasoline mileage increased by an average of 12%. Oil mileage increased 27% and even 35%. Motors ran cooler. There was less oil the dreaded grinding of metal on metal, which works serious harm —and harm that grows more seri- Solid line shows bow ordinary oil breaks down wnder load, sending sp the temperature of metal swrfaces.

Or in more simple lan- guage: How to provide an oil that will stay put upon a metal surface, and still will not be too thick nor of too heavy a consis- TESTS made with ific cars before this 0il was offered to the public Dodge 1a an actual 1080 mile road test, run from Sept. 24th to Oct. 22d, 1928, using a Dodge Touring Car, the new “Standard” Motor Oil showed a decided saving in hoth gasoline and oil consumption: 40.9% increase in oil mileage 10% increase in gas mileage There was also apparent a much smoother operation of the motor, more power and less sluggishness on the hills. Buick A Buick,in a test of the new “Standard” Motor Qil for carbon the car was examined before the tests, there were heavy carbon deposits on cylinder heads and pis- tons. The new “Standard” Motor Oil was then put in the crank-case and the car run 2,969 miles and again examined. Most of the carbon bad disappearsd —the slight amount remaining was easily wiped off with a doth. Ford 1o 2 609 mile road test on a Ford Coupe run from Sept. 24th to Oct. 22d, 1925, the new “‘Standard” Motor Oil showed a substantial de- crease in both oil and gas con- sumption: 12.8% increase in oil mileage] 12.3% increase in gas mileage And the driver could actually feel a difference in the operation of his car —improved pulling, snappier pickup, elimination of the drag which the motor had previously shown on hills and the removal of the carbon which had been in the motor when the new oil was putin. Hudson In 2992 milcroad test,run with a Hudson Touring Car from Sept. 24th to Oct. 22d, 1925, the driver, a skilled mechanic, tabulated these results: 27.1% increase in oil mileage 12.4% increase in gas mileage And che driver reported decidedly smoother operation of the motor at all speeds, more power and less drag on the hills. Mack Tested on the road from Sept. 24th to Oct. 22d, 1925, for 3,779 miles in a big AC Mack Truck, the new “Standard” Motor Oil showed splendid results: 19.5% increase in oil mileage 20.9% increase in gas mileage Less friction Cooler motor Increased power Less motor drag Other Mack Motors tested for car- bon deposit demonstrated that the new “Standard” Motor Oil removed existing carbon and deposited none itself. White in astiff 2,947 mile road test with a 5-ton White Truck run from Sept. 24th to Oct. 22d, 1925, the new “Standard” Motor Oil proved thatits effecton oiland gasolinecon- sumption is on the side of economy: 19.5% increase in oil mileage 13.8% increase in gas mileage Additional tests on White truck motors with “Standard” Motor Oil show a detided decrease in carbon depasit, less friction, cooler motor, smoother running at all speeds and better all *round lubrication. leakage. Less carbon formed. Carburetors were adjusted to leaner mixtures. The above facts speak S for themselves On this page are given results ot tests, which require no comment. Experienced motorists who have tried this new oil have been frankly surprised that any lubricant could bring about so considerable a change in the operation of their cars. Many of them tell us they can actually «feel the difference™ while driving. «Standard” Motor Oil is to be found on sale now at Standard QOil Service Stations and at dealers. 7 Advantages found only in “Standard™ Motor Oil 1 Constant lubrication-film on metal surfaces. Frictionless operation, in a practical sense, even upon starting after idle- ness. 3 Less “breaking down* un- derload or at high speeds. 4 More miles per quart of oil and less crank-case di- lution. 5 Better hill climbing and smoother operation in high gear at low speeds. 6 Negligible carbon, clean motor and clean spark- plugs. 7 Actual saving in gasoline, with or without carbure- tor adjustment. e STANDARD OIL COMPANY (New Jersey) CARBON Remarkable demonstration when you drain ont your oil In addition to its other virtues, this new “Standard” Motor Oil is extremely effective in cleanin cylinder walls, piston heads an “ | evenspark plugs. Its black color after the first filling has been drawn off shows that it affects existing carbon. Drive 300 miles with the new oil—then drain your crank-case. Having dis- lodged this objectionable ma- terial you will wantto getrid ofit. Having filled up the second time with “Standard” Motor Oil it is unnecessary to refill oftener than every 500 miles, or at your usual draining ir‘;ternls eedless to after the second filling, little :"no carbon will form. If any deposit is made it can be easily removed.
