A TRULY WONDERFUL DISCOVERY.

GOOD X'EWS TC MOTORISTS. WANGAXUI CHEMIST'S SOLUTION OF THE EXPENSIVE PEIITOL PROBLEM. INEKVIEW WITH ME. ANDHEW DOIG. 'Sew Zealand has good reason to feel justly proud in the latest discovery of Mr. Andrew Doig, chemist, of Wangunui. This enterprising analyst has concentrated for some considerable time on the problem of a petrol eeonomiser, and lias succeeded in giving to the world a preparation wlhich, in the hands of an influential company, has now been registered and protected the world over. Like many other inventions, Mr. Doig's discovery is a product of war conditions. The cost of petrol (aside altogether from its threatened scarcity from time to time) has been such that for years mechanics of all shades and grades have devoted themselves to the task of thinking out new and improved principles, all with the idea of making a gallon of petrol yield more mileage. Mr. (Doig has proved to the motoring niftlic tlhat to a great extent we have all looked altogether at the wrong end of things. At least he has demonstrated that what was wanted was not so much a different system of carbuerttion, but a system whereby every drop of spirit used would yield its full capacity of power with the carburettor at present in use.

The fact that under ordinary conditions combustion is not complete when a gallon of petrol is fired in an engine, opened up to Mr. Doig an opportunity for scientific research. He determined to concentrate on the discovery of ways and means whereby all waste would foe eliminated • and the combustion made so perfect as to use up every atom of spirit and, as far as possible, leave not even the slightest trace of carbon oa the cylinders. This is exactly what Mr. Doig has accomplished, and the wonderful results which those who use his preparation experience is purely the natural sequence which combustion, aad ithe practical elimination of carbon deposit, would be expected to bring about. The resuft Is iwo-fold —motor spirit goes further, and the engine also runs more "sweetly." It was during the. holiday season that a member of the staff of a leading New Zealand newspaper called upon Mr. Doig in Wanganui, and learned of many' of (■he tests and triumphs of this renowned petrol economiscr called "Novoko." There, lying on the table before Mr. Doig was a bundle of original letters From all parts of New Zealand, each tell.Ung of tests that bad been carried out on motor vehicles from 3% li.p. cycle:, to the larger motor buses and lorrjes. Every style and power of motor-car had Apparently been tested, and all alike told of one result—greater petrol mileage and sweeter running engines. It was remarkable to note how many spoko of the difference in pulling power of thell' engines on bills. The simile of "getting tftere" with the speed of a thoroughbred was the natural rellcction as one listened to the unanimoif* reports of the comparative condition of things with and without "Novoko." The improved way the engine "picks up" in starting was a point mentioned by many correspondents. The actual method of "administering" Novoko is simplicity itself. In proverbial, chemists' language, the "dose" is two tablespoonfuls (one ounce) to each gallon of benzine- When the petrol tank of the car i 3 about to be filled, all one needs to do is to previously add 4 ounces to each four-gallon tin of motor spirit. Once the car is accustomed to the new condition of tihings the carburettor will run on a much "leaner" mixture, and it is necessary to cut down the jet as far as possible, and open up the air. This is where the saving is effected.

Mr- Doig, in speaking of this point, gave the representative a few technical figures, which were certainly convincing. These, stated brifly, were simply that an engine—like human beings—must breathe air, or oxygen, and whereas I J ,040 volumes of air are required for the complete combustion of one volume of ordinary petrol vapor. "Novoko" provided a spirit which would take a larger proportion of air, and so increase the power of the engine from the same amount of petrol. In some cases "Novoko" enabled the engine to "breathe" dpuble the amount of air, and thus double the mileage covered from a given quantity of petrol.

The fact that "Novoko" is guaranteed as positively harmless in the very least degree to all metals, was a matter particularly stressed by Mr. Doig. Nothing had been left to chance, and by way of demonstrating his point even more convincingly, Mr. Doig exhibited a sealed bottle, containing motor spirit and "Novoko" mixed in proper proportions. In this bottle—wlhich has now been sealed for the best part of a vear—were all sorts of coins, copper-plate and wire steel and iron parts, etc., and the slightest trace of corrosion or harmful effects was not noticeable on aiiv one of them. Mr. Doig was particularly anxi ous that this should be made known to the public. His company guarantees the preparation to, be absolutely harmless to all metals, and only lasting good can result from its use. "Novoko" even now, he said, was in great demand, and this was entirely the result of the fact that motorists had discovered for themselves how much their petrol bills could be reduced, and with what greater ease their engines run, resulting, naturally in more pleasure and pride in the runn;ng of one's earTo New Zealand motorists tbe verdict of Mr. Henry J. Ranger, of Ohristclmrch, of Chevrolet fame, is of the utmost significance. Mr. Eanger, in his tests witl "Novoko,'' got up to 41 miles to the gallon of petrol. It should be borne in mind that Mr Ranger, up to the pres ent, has guaranteed a fivo-seater Chevrolet to do 29 miles to the gallon of benzine before a purchased need pay for his car. His record with "Novoko" mixture shows a great improvement in the mileage.

Mr, Thornton, the enthusiastic partner of the Canterbury Motor Company, Ltd Christchurch, tells of his experience with nn old ear which had been running 'or years, and was badly in need of a good overhaul and priming up. This car, with ''Novoko," showed an increase of ten miles to the gallon. This experience has naturally made Mr. Thornton nn enthusiastic salesman f" "Novoko." 'We recommend it every ne!" said lie, when interviewed by the pressman, who subsequently visited him in Christ'elrarch.

j Far from being "up against it,'' motor garages everywhere are enthusiastic over .Mr. Doig's discovery- It is hailed as. the boon and blessing which the trade has simply been waiting for, hecause it means cheaper fuel cost, and consequently tends," to encourage the habit of motoring. The experience of both Mr. Banger and Mr. Thornton was that their mileage was increased by practically 50 per cent, with the addition of "Novoko." Mr. John M. Gibson, of Gibson and Paterspn, Ltd., Wagnamn and Patea, had the same experience, his car having increased its mileage from 20 8-10 th miles to 30 0-10ths tt the gallon, Plunie benzine being used. Mr. T. IT. Battle, architect, Wanganui, improved his mile» age from 10 to 21—one-third increase. Mr. W- Oraffin, the well-known "Buick" agent, of Wellington and Wanganui, testifies to getting from 30 to 40 per cent. more out of his Buick with "'Novoko." Mr. C- H. Chavannes, the popular Ford enthusiast, of Wanganui, got 10 miles more out of his Ford car. Mr. Stanley Morgan, one of the buyers for the New Zealand 'Fanners' Meat 'Packing and Bacon Co., Ltd., Wellington, actually proved his tests to mean a saving of from £2 lOa to .£3 a week by using "Novoko" —this is "some" saving, surely, and should speak loudly to those who are constantly using a motor-car. Mr. T. B. Jefcoate, the Wanganui buyer for the New Zealand Refrigerating Co., Ltd., increased his mileage from 17 to 24 miles, also found bis engine pulled better and ran sweeter. Mr. Arthur HLees, buyer for "Mgety's, Ltd., got an extra six miles to the gallon out of his car—and some rough, billy work is accomplished by him every day. Of more than ordinary interest are the results proved by Mr. C. Savage, motor mechanic, of Wanganui. Tests carried out with private cars resulted in increases as follows:—Buick, owned by Mr. J. Craig, Wangaehu, increased from 20J to 31J miles with "Novoko"; Buick owned by Mr. J. H. McLean, Marten, increased from 24J to 36.8 miles; Ford car owned by himself showed an improvement of 10 miles—from 25% miles without "Novoko" to 35$ miles with it; Studebaker, owned by Mr. AV. Glasgow, Turakina, increased" from 16 to 22.G miles; and a Buick belonging to Mr. G. Glen, of Makirikiri, increased its efficiency by 11J miles to the gallon, rising from 22J miles without "Novoko" to 34 miles with it. Mr. J. Murray, the popular "Glaxo" general manager, of Palmerston North, states he gave Mr. Doig's "Novoko" exhaustive tests, and proved that from (10 per cent. " per cent, increased running was . stationary engines, and 25 per cent, to 40 per cent, greater power on motor-cars- In every instance he found the carburettor hr.d to be readjusted to obtain the desired results, the petrol feed being reduced and the air inerased.

Mr. F. J. Nalhr.n, of Joseph Nathan and Co., Ltd., Wellington, increased his mileage from 133 without "Novoko" to an average of 18 to 19 witli "Novoko. M •His car was a 40 h.p. C-eylinder Hudson. This test was carried out in motoring on all sorts of rough roads, in all conditions of weather- His firm now use "Novoko" regularly in their largo motor waggons In country districts. Well-known doctors and professional men generally corroborate the statements and tests of leading commercial men as to the merits of "Novoko," and many instances can 'be .cited of truly marvellous results obtained by motorcyclists in 'both solo and side-car work. The merits of "Novoko" for uss in stationary engines are attested to by Mr. W. Mason Bayly (of Bett and Bayly's Motor Garage, Pahnerston North), one of the prominent and popular motorists of the Wellington province. Associated with Mr. Bayly was his foreman motor mechanic, Mr. Ernest A. UUrbom. The test was carried out in September last "in a fair and impartial manner, absolutely under the control of ourselves, without any interference or advice from anyone connected or interested in "Novoko"—these are Mr. Bavjy's own words. The plant used was a 3* lip. stationary benzine engine, coupled to a 25 to 40 dynamo connected up to a lighting set. The engine was allowed to run till stopping point on a half-pint of Kaliff motor spirit. A further halfpint of "Novoko"-treated motor spirit was then used, and the engine once more set a-going, with the feed and air adjusted. Every condition was similar exactly in the two runs, and the "Novoko" proved itself triumphant to the tune of "Novoko" treated benzine would run in running time, with exactly the same amount of fuel. On a'bove figures one gallon of plain 'benzine would run for four hours 32 seconds, while one gallon of 'Novoko"-treated benzine would run for seven houns 31 minutes 12 seconds. It would therefore require one gallon seven pints of plain beninze to run as long as one gallon of "XovoW-treated benzine. The cost of one ounce of "Novoko" sufficient t 0 treat a gallon of benzine is 2y 4 d. One gallon seven pints of benzine at 3s 6d per gallon costs 6s fl%d. Deduct from this the cost of one gallon of benzine at 3s (id, and one ounce of "Novoko" at 2543. a total of 3s S'4d, and we thus find the farmer can save 2s lOjd per gallon on a milking machine engine. This test has brought about such a condition of things that to-day throughout the dairying districts of the North Island there is ft phenomenal demand for "Novoko." It is used extensively on stationary engines for the driving of milking machines.

What Mr. Doig's preparation will mean to the motorists of New Zealand it would be difficult indeed to compute. Already the line is having a brisk sale and arrangements are now being made to carry big quantities in stock locallv to supply the ever-increasing demand. Mr. Doig explained that this bad really been rather a problem to his company They were anxious to make up as niuch stock aa possible, but their factory had really never been able to keep pace with the orders received—they were always .behind in their deliveries. This, however, would soon be solved, and the motoring public could rely upon being able to regularly procure "Novoko" at any country garage—as it could now be procured at all the leading city garages—in pint, half-gallon, and gallon tins. 6
