A TRULY WONDERFUL DISCOVERY

New Zealand has good reason to feel justly proud in the latest discovery of Mr. Andrew Doig, chemist, of Wangauui. This enterprising analyst has concentrated for some considerable time o u the problem of a petrol economiser, and has succeeded in giving to the world a preparation wiliich, in the hands of an influential company, has now been registered and protected the world over-

gallon of benzine. When the petrol tank of the car is 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 tilings 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 briefly, were simply that an engine—like human beings—must lireathe air, or oxygen, and whereas 1!,,040 volumes of air are required for the complete combustion of one volume of ordinary petrol vapor. "Xovoko" 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 "Xovoko" enabled the engine to "breathe" double the amount of air, and thus double the mileage covered from a given quantity of petrol. The fact that "Novoko" in guaranteed as positively harmless in the verv 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— which has now been sc.iled for the best part of a year—wera_all sorts of coins, copper-plate and wire, steel and iron part?, etc.. and the slightest trace of corrosion or harmful effects was not noticeable en nnv one of them. Mr. Doig was particularly anxi ons that this should he made known to the public. His company guarantees the preparation to be Absolutely harmless to all metals, and only lasting gocjd can result frorn its use. "Xovoko"! even now, he said, was in great demand, and this was entirelv the result of tWe fart that motorists had discovered for themselves flrow much (heir petrol bills could be reduced, and with what greatet ease their engines run, resulting, naturally, in more pleasure and pride in the running of one's car- I To Xew Zealand motorists the j-erdiet of Mr. 'Henrv .T. Tianecr. of Ohrist4hnrch, of Chevrolet fn'»n. 5s of tlio utmost significance. Mr. Ranger, in his testis w ; *' "Xovoko.'' cot up -to 41 miles to the gallon of petrol. Tt should be borne in mind that Mr. Tl.inwr, up to the ores ent. has jniarnnteo'i <\ fivc-°eatpr' Chev ••olet to do 2!) miles to the gallon "' benzine before a. pnrel'nspr need pay for >ms car. TTis record with "Xovoko" mixture shows a great improvement in the milenso. Mr Thornton, the enthusiastic partner of the. Canterbury Motor Oompanv. Ltd.. Christehureh, tells of his experience with an old enr which hid been running 'or vears. and was hadlr in need of « good overhaul and priminsr up. This ear. with "NovoVo." showed ki\ increase of ten miles to the gallon. This experience has naturally made Mr. Thornton "tt enthusiastic salesman for "Xovoko." •'We recommend it pvprv time!" said ' h n . when interviewed the pressman, who subsequently visited him in Christchurch.

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, because it means cheaper fuel cost, and consequently tends to encourage the habit of motoring. The experience of both Mr. Ranger 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 Paterson, Ltd., Wagnanui and Patea, had the same experience, his car having increased its mileage from 20 S-lOth miles to 30 C-lOths to the gallon, Plume benzine being used. Mr. T. H. Battle, architect, Wanganui, improved his mileage from Hi to 21—one-third increase. Mr. W- Draffin, the well-known "liuick" agent, of Wellington and Wanganui, testifies to getting from 30 to 40 per cent, more out of his Buiclc with "Novoko." Mr. C H. Chavannes, the popular Ford enthusiast, of Wanganui, got 1(1 miles more out of his Ford car. Mr. Stanley Morgan, one of the buyers for the New Zealand Farmere' Meat Packing and Bacon Co., Ltd., Wellington, actually proved his tests to me:in a saving of from £2 10s to £3 a week by using "Novoko"—this is "some" saving, surely, and should spoak loudly to those who are constantly using a motor-car. Mr- T, E, .lefcoate, the Wanganui buyer for the New Zealand Refrigerating Co., Ltd., increased his mileage from 17 to 24 miles, also found his engine pulled better and ran sweeter Mr. Arthur TT. Lees, buyer for Dalgety's. Ltd., got an extra, six miles to the gallon out of his car—and some rough, hillv work is accomplished by him every day. Of more than ordinary interest are the result* proved bv Mr. C. Savnffe, motor mechanic, of Wanganui. Tests carried out with private cars resulted in increases as follows:—Buiek, owned by Mr. .T. Craig. Wangaehu. increased from 201 to 3]J m,iles with "Novoko": Buiek owned liv Mr. .T. 11. McLean. Marton. increased from 241 to 3C.S miles: Ford car owned bv himself showed an improvement of 10 miles—from 23'/- miles wfchoiit "Novoko" fo 35J miles with it; Stildebnker. owned bv Mr- W. Glasgow. Tnrak-inn. increased from M to 2?<5 miles; find a Buiek belonging to Mr. G. Glen, of Makirikiri, increased its eflTtcionev bv 1H miles to the gallon, rising from 22i miles without "Novoko" to 34 miles with it. Mr. -T. Murray, the nopulnr "Glaxo" general manager of Palmerston North, states he save Mr. Dois's "Novoko" exhaustive tests, and proved that from flO per pent, to *"• per cent, increased running was given stationary ensines, and !?!i per cent, to 40 per cent, greater power on r<otor-cnrs. Tn everv instance lie found the carburettor had to be readjusted to obtain the. desired results, the netrol feed being reduced and the air increased. Mr. F. .T. 'Nathan, #f Joseph Nathan nnd Co., Ltd . Wellington, increased his mileage from 13.(1 without "Novoko" to *u average of IS to 10 with "Novoko." FTis car was a 40 h.n. (1-cylinder Hudson. Phis test was carried out. in motoring nn all sorts of rough roads, in all conditions of weather. His firm now use

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 now and improved principles, all with the idea of making a gallon of petrol yield more mileage.

■Mr. Doig has proved to the motoring public that to a great extent we have all looked altogether at the wrong end of tilings. At least he lias demonstrated that what was wanted was not so much a different system of carburettion, 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 .1 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 be 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 on 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, and the practical elimination of carbon deposit, would be cxpectpd to bring about. The resurt Is two-fold—motor spirit goes further, and the engine also runs more "sweetly." It was during the holiday season that a member of the stafl" of a' leading NewZealand newspaper called upon Xr Doig in Wanganui, and learned of many of the tests and triumphs of this reno'vned petrol economiser called "Novoko." There, lying on the table before Mr. Doig was a bundle of original letters from all parts of Xew Zealand, each te|. iing of tests that had been carried out on motor vehicles from 3% h.p. cycles to the larger motor buses and lorries. Kvery 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 spoke of the difference in pnllin? power of tieli' engines on hills. The simile of "getting tihero" with the speed of a thoroughbred was the natural reflection as one listened to the unanimoit* reports of the comparative condition of tilings with and without "Xovoko." The improved" way the engine "picks up" in starling was a point mentioned by many corres~ pondents. The actual method of "administering" Xovoko is simplicity itself. In proverbial chemists' language, the "dose" is two tablespoonfuls (one ounce) to each

GOOD NEWS TO MOTORISTS WANGANUI CHEMIST'S SOLUTION OF THE EXPENSIVE PETROL PROBLEM INTERVIEW WITH MR. ANDREW DOIG

"Novoko" regularly in their large motor waggons iu 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 use in stationary engines are attested to by Mr. W. Mason Bayly (of Bett and Bayly's Motor Garage, Palmerston North), one of the prominent and popular nlo* M torists of the Wellington province. Associated wijh Mr. Bayly was his motor mechanic, Mr. Krnest A. The test was carried out in Scptem&er 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. Bayly's own words. The plant used was a 3 h.p. stationary benzine engine, coupled to a 25 to II) 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 half' pint of "Novoko"-treated motor spirit was then used, and the engine once mor* set a-going, with the feed and uir adjusted. Kvery condition w;is similar exactly in the two runs, and the ''Novoko" proved iisclf triumphant to the tune of an increase of just over .78 per cent, in running time, with exactly the same amount of fuel. On above figures one gallon of plain benzine would run for four hours 3-2 seconds, while one gallon of 'Novoko"-trented benzine would run for seven hours 31 minutes 12 seconds. It would therefore require one gallon seven pints of plain benin/e to run as long as one gallon of "N'ovolro '-treated benzine. The cost of one ounce of "Novoko" sufficient to treat a gallon of hen/yiie is One gallon seven pints of benzine at 3s (Id per gallon costs (is fi.j/,il. Deduct from this the cost of one gallon of benzine at .'ls fid. and one ounoic of "Novoko" at a total of ' 3s S'/td. and we thus find the farmer can save 2s lO.kl per gallon on a milking machine engine This test hag brought; about such a. condition of things that t.o-dav throughout, the dairying dis. tricts of the North Island there Is a phenomenal demand for "Novoko." It is used extensively on «tntin"irv 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, rind arrangements are now being made to carry big quantities in stock loeallv to supply the ever-increasing demand. Mr. Doig explained that this had realljr been rather a problem to his company. Thev were anxious to make up as much stock ns 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 rclv upon heing able to regularly procure "Novoko" at any country gnrnffe—as it could now he procured at. all the leading city garages—to pint, half-gallon, and gallon tins. *
