| The remarkable discovery was made that such oils, used many times, and re-refined many times, actually became better oils. F.{Mr Friese} E.{Mr Elliott - Chief Engineer} Rowland, Oregon State College, states : “ We have found that waste crankcase oil, on refining, produces an oil equal to the original.” A statement made by the Pennsylvania State College in August 1931, was as follows : “ If an automobile is equipped with a proper Oil-filter, there is no advantage in ever changing crankcase oil.” The LUBER-FINER cleans the motor oil while the oil circulates through the motor. It is continuous in its operation, removing and retaining all abrasive particles, preventing excessive dilution and returning the oil to the crankcase a clean and full-bodied lubricant free from all foreign matter, thereby eliminating the draining of the crankcase for an indefinite period, it being only necessary to replenish the oil to replace normal consumption. Seyer and Allen, in a report on Laboratory tests on both new and used oils, state that used oils, when refined, would be superior to new oils. Referring to the report of Seyer and Allen, Dr. Winslow H.{Arthur M. Hanbury - Head Complaints} Herschel, of the Bureau of the Standards, states : “ The claim is entirely reasonable because we know that if an oil is subjected to oxidation in the engine, the more unstable portions of the lubricant will be oxidised and if the oxidised portion is removed the remaining oil should be more stable and durable than the original oil.” “ Eighty per cent. of present motor repair costs are the result of contaminated lubrication.” National Automobile Chamber of Commerce of the U.S.A. “ The amount of solids actually removed from lubricating oil by filters is very small, averaging only 2.56 grains per 1,000 miles.” University of California, Bulletin 499. Present day types of filters only STRAIN the oil through CLOTH, FELT, WASTE, METAL STRIPS, CHARCOAL, ETC., removing the comparatively large substances only. The finer carbon and other abrasives which cut, grind and polish away the cylinder walls, piston rings, crankshaft bearings and other working parts of the motor, pass through the Filters and are ALWAYS present in the oil stream and crankcase of the motor in spite of the fact that the motor is equipped with a filter. This is why the lubricating oil in the crankcase of the motor is dirty and contaminated with foreign substances which are highly abrasive. In the Oil Stream, abrasives reach every moving part of the motor, “ Serving to wear out these parts FIVE TIMES faster than would occur if the oil in the crankcase were clean.” Charles W. McKinley, Petroleum Engineer. “ The possibility of cutting automobile oil bills in half, by a new method of refining oil, was predicted at a meeting of the American Society of Mechanical Engineers, to-day.” New York N.Y.U.S.A., December 8, 1932. The report said that under the new system, the crankcase will never have to be drained and the engine will develop more power and use less petrol. Ten years of practical tests were cited. The oil in these tests was crankcase drainings, the mucky stuff motorists throw away. This oil was cleansed and in all cases, was claimed to have brought forth a BETTER lubricant than the original. Bear in mind that “ OIL NEVER WEARS OUT, but the weak elements are destroyed by action of the motor, and re-refining recovers only the FINEST, TOUGHEST and most SERVICEABLE part of the lubricant, which is motor seasoned and is, therefore, BETTER than new oil and will deliver 20 to 40 per cent. more service in mileage and motor upkeep.” IF YOUR ENGINE NEEDS OIL IT NEEDS A LUBER-FINER Luber-finer LUBER-FINER (ENGLAND) LTD (Associated with R.{Sir Henry Royce} H.{Arthur M.
