A TRULY WONDERFUL DISCOVERY

New Zealand has good reason to feel justly proud in the latest discovery of Mr. Andrew Doig, chemist, of Wanganui. This enterprising analyst has concentrated for some considerable time on the problem of a petrol economiser, and has succeeded in giving to the world a preparation which, 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 public that to a great extent we have •ill looked altogether at the wrong end of tilings. At least he has demonstrated that what was wanted was not so much a different system of earburettion, but a system whereby every drop of spirit used would yield its full capacity of power with-tiie 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 be eliminated and the combustion made so perfect as to use up every atom of spirit and, as far as possible, leave, not even (he 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, aad the practical elimination of carbon deposit, would be -expected to bring about. The rcsitft is cwo-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 Yin Doig in Wanganui, and learned of ma!ny of the tests and triumphs of this renowned ' petrol economiser called "Novoko." There, lying on the table before Mr. Doig was a bundle of original letters , from all parts of New 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. , Every style and power of motor-car had , apparently been tested, and all alil; 0 told ] of one result—greater petrol mileage i and sweeter running engines. It was re- J markable to note how many spoke of the difference in pullin? power of tlelv engines on hills. The simile of "getting flhere" with the speed of a thorough- ' hred was the natural reflection as one listened to the unanimou'* 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 corres" ' pondents. ' ' ( The actual method of "administering" • Novoko is simplicity itself. In prover- i bial chemists' language, the "dose'i is i two tablespoonfuls (one ounce) to each (

gallon of benzine. When the petrol ta.nk 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 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 briefly, were'simply that an engine—like human beings—must breathe air, or oxygen, and whereas 11,010 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 eases "Novoko" enabled the engine to "breathe" double Hie 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 "No. voko" mixed in proper proportions. In this bottle—which has now been sealed for the best part of n year—werp 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 rn nnv one of them. Mr. Doig was particularly anx> ous that this should be made known to the public. His company guarantees the preparation to bo :»bsolutoly harmless to all metals, and only lasting good can result from its u=e. "Novoko" even now, he said, was in great demand, and this was entirelv 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 ruining of one's car. To New Zealand motorists the verdict of Mr. Honrr -T. Ranger of Obristchnren, of Chevrolet fa""-, is of ihn utmost significance. Mr. Banger, in his tests w-v "Novoko.'' rot up to 41 miles to the irnllon of petrol, Tt should be borne in mind that Mr. Hanwr, up to the present, has ruamntoo'i i five-=eatcr Chev •olet to do 2!) miles to the gallon nf benzine before a p"rcl«n«cr need pav for !>is car. TTis record with "Novoko" mixhiro shows a great improvement in the mileage. Mr Thornton, the enthusiastic partner the Canterbury Motor Company. Ltd., Christchurcb, tells of his experience vith an old or which bid been running or vears. and was badlv in need o f •> jood overhaul and primin<r up. This ■ar. with "Novoko," showed an increase >f ten miles to the gallon This exneri>nco has naturally made Mr. Thornton ■n enthusiastic salesman for "Novoko." 'We Tecommend it every time!" said i». when interviewed hv the nressman, vho subsequently visited him in Christ■hurch.

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 enaourage 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 "Xovoko." Mr. John M. Gibson, of Gibson and Paterson, Ltd., Wagnanui and Patea, had the same experience, his car having increased its mileage from 20 8-lOth miles to 30 C-lOths to the gallon, Plume benzine being used. Mr. T. H. Battle, architect, Wangamii, improved his mileage from Hi to 21—one-third increase. Mr. \V- Draflin, the well-known "Buick" agent, of Wellington and Wangamii, testifies to getting from 30 to 40 per cent, more out of his Buick with "Xovoko." Mr. C H. Chavannes, the popular Ford enthusiast, of Wanganui, got 10 miles more out of bis Ford car. Mr. Stanley Morgan; one of the buyers for the New Zealand Farmers' Meat Packing and Bacon Co., Ltd., Wellington, actually proved bis tests to mean a saving of from £2 10s to .-£3 a week by using "Xovoko"—this is "some" saving, surely, and should speak loudly to those who are constantly using a motor-ear. Mr. T. K. .Tefeoate, the Wangamii buyer for the Xew Zealand Refrigerating Co., Ltd., increased his mileage from 17 to 24 miles, also found his engine pulled better and ran sweeter. Mr. Arthur H. Leos. buyer for Daliety's. Ltd.. got on extra, six miles to the gallon out of his ear—and some rough, billv work is accomplished by him every day. Of more than ordinary interest are the results proved by Mr. O. Savage, motor mechanic, of Wangamii. Jests carried out with privatp cars resulted in increases as follows:—Buick, owned by Mr. .T. Craig. Wangachu. increased from 20J to 3U miles with "Xovoko": Birchowned by Mr. .T. TT- McLean, Marton. increased from 24A to 30.S miles: Ford ear owned hv himself showed an improvement of 10 miles—from 23>/> miles without "Xovoko" to SiiJ miles with it; Studebnker. owned by Mr W. Glasgow. Tnrakina. increased from I<> to 2? ft miles; nnd a Buick belonging to Mr.-1. Glen, of Ma-kirikiri, increased its efficiency Try 1U miles to the gallon, rising from 221 miles without "Xovoko" to 34 miles with it. ■Mr- .T. Murray, the Popular "Glaxo" general manager of Pabnerston Xorth, states be save Mr. Poirr's "Xovoko" exhaustive tests, nnd proved that from 00 per cent, t" 7o per cent, increased running was given stationary engines, and 25 per cent, to 40 per cent, greater power on motor-cars. Tn every instance he found the carburettor had to be readjusted to obtain the desired results, the netrol feed being reduced and the air increased. Mr. Y. J. Xathan, of Joseph Xathnn end Co., Ltd . WellinPton. increased his mileasre from 13.fi without. "Xovoko" to en average of IS to 10 with "Xovoko * His car was a 40 h.n. fi-cylinder Hudson.

GOOD NEWS TO MOTORISTS WANGANUI CHEMISTS SOLUTION OF THE EXPENSIVE PETROL PROBLEM v INTERVIEW WITH MR. ANDREW DOIG

"Xovoko" regularly in their large moto* waggons in country districts-Well-known doctors and professional men generally corroborate the statements aud tests of leading commercial men as to the merits of "Xovoko," and many instances can be cited of truly marvellous results obtained by motorcyclists in both solo and side-car work, The merits of "Xovoko" for use in stationary engines are attested to by Mr. W. Mason Bayly (of Bett aid Bayly's Motor Garage, Palmerston North), one of the prominent and popular nw» torists of the Wellington province. soeiated with Mr. Bayly was his forem J|H motor mechanic, Mr. Kmest A. The test was carried out in Septeaßef last "in a fair and impartial manner, absolutely under the control of ourselves, without any interference or lidvice from anyone connected or interested in "Xovoko"—these are Mr. Bayly's own words. The plant used Was a 3 h.p. stationary benzine engine, coupled to * 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 "Xovoko"-treated motor spirit was then used, and the engine once more set a-going, with the feed and air adjusted. Kvery condition was similar exactly, in the two runs, anil the "Xovoko" proved itself triumphant to the tune of an increase of just over 7S 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 32 seconds, while one gallon of 'Xovoko"-!reated benzine would ruii for seven hours 31 minutes 12 seianda. [t would therefore require one gallon sieven- pints of ulain. lienin/c to rim aa long as one gallon of "Xovoko "-treated benzine. The cost of one ounce of voko" sufficient to treat a gallon of benzine is One gallon seven piiltg of benzine at 3s 0:1 per gallon co«ta lis fi-y,d. Deduct from this the cost of one gallon of benzine at 3s (id, nnd one mince of "Xovoko" at 2%<1, a total of 3s B'/,d. and we thus find the farmer :an save 2s IOJd per gallon on a milking machine engine This test hai brought about such a condition of things 'hat to-day throughout the dairying did. rricts of the Xorfn Island there is a phenomenal demand for "Xovoko." It is used extensively on stationary enlines for the driving of milking marines. What Mr. Doig's preparation will mean to the motorists of Xew Zealand t would be difficult indeed to compute. \lready the line is having a brisk sale, Mid arrangements ere row being made o carry big quantities in stock local I v o supply the ever-increasing demandVfr. Doig explained that this bad really icen rather a problem to his company, rhev were anxious to make up as much stock as possible, hut their factory had •eally never been able to keep pace with :he orders received—they were always >ehind in their deliveries. This, how'ver. would soon be solved, and the mooring public could relv upon toeing able ;o regularly procure "Xovoko" at any 'ountry garasc—as it, could now be proured at- all the leading city gar«ges»-in )int, half-gallon, and gallon tins. *
