The reason lies in the fact that gasoline conditions as they now ex ist were foreseen by the engineers of the 01-ds company, and special provis ion made to meet them. Successfully using low grade fuels is simply a problem in sustained vap orization. The fuel must first be burned into gas, and then kept in that condition until it reaches the cylin ders. In the Oldsmobile, a unique ar rangement of gas passages is employ ed at this end, an especially note worthy application of this principle being found in the Oldsmobile eight cylinder. In the first place, the carburetor on this car is situated between the cylin- j der blocks, where it is bathed in a constant stream of warm air from the radiator and from the motor. Xext the carburetor manifolds, which lead to the intake manifolds proper, are exceptionally short and surrounded by large water jackets. I which prevent any condensation of j gas at these points. Finally, the intake manifolds of the ! motor are cast integrally with the ex-1 haust. so that the exhaust heat is uti-1 lized to keep the gas in suspension and I Insure its delivery to the cylinders in I proper conditions. The result is not only to insure the j ready consumption of low grade gaso line, but a fuel company that is note worthy. The gasoline average of the; Oldsmobile Eight is thus from 12 to i 14 miles a gallon, which is exception-1 al for multi-cylinder motors. The Oldsmobile Four has always To arrive at the "life expectancy" of Quaker Tires, a lot of letters from Quaker lire users, selected at random was turned over to an accountant to examine and average the mileage reported. The results follow: £ ,x c Fifte , en ma I kes of cars - equipped with practically all sizes of Quaker Tires, in use in 14 otites, showed an average mileage of 10,629 miles. The mileage delivered by Quaker Tires, in characteristic cases, where two or more tires were used on the same car, follows: Res P ecti ye mileage 3 tires, 1 4,000, 1 2,085, 1 3,000; 4 tires, 10,183, 10,281, 10,213. 11,000 ; 4 tires, 11 000 each (still m use) ; 4 tires, 9000 each (still in use) ; 2 tires 12,500 (still m use), 12 500; 2 tires, 8200, 7387 (still in use) ; 2 tires, 7000 each (still in use) ; 2 tires, 1 1,227 each (still in use) ; 2 tires, 14,000 each (still in use). Of course, there are reasons for such service as Quaker Tires render; one reason is the sturdy construction, with fu 1 measure of materials ; another reason is the the rub ber is treated—our secret and exclusive process of tempering. Tempering tones some of the natural properties of high-grade crude rubber and de velops certain latent properties, with the result that there is secured a perfect balance of hardness, toughness elasticity, resiliency and tensile strength, affording maximum shock absorption and greatly increased durability. QUAKER MULTI-TUBE is a marvel of elasticity and tensile strength, due to the tempering of the rubber.

Sun Sedan a Model For Summer as Well "The automobile is no longer a lux- j ! ury to be used only a few months in 1 the year," declares H. A. Minturn, : Engineer. Sun Motor Car Co. "The automobilist now demands a car that he can use in any kind of weather,! in fact the more disagreeable the j i weather the more he needs his car. "The millionaire, of course, has his limousine for winter use and his touring car for summer. The wealthy man has his touring car with two itops, a winter top and a summer top, j but the average man wants an all, season car. "The Sun Sedan has been designed to meet the requirements of the buy er who desires a car of general util- I ity at a reasonable price. "All doors, windows and panels may \ be easily removed giving maximum j ventilation for summer, in fact the j Sun Sedan top is really cooler in sum-' mer than an ordinary old style top as the double thickness structure gives! perfect insulation against heat. On j the other hand when the winter comes the doors may be instantly replaced giving a coziness that has heretofore been found only in the most expen sive enclosed cars. SUN LIGHT SIX EFFICIENT TYPE ♦ Exclusive Features Include Dual Ejector Exhaust Mani- j fold and Special Design The Sun Light Six which is built by ! the Sun Motor Car Company, Elkhart, j Ind., is a high-powered light weight ■ six-cylinder oar selling at $1095. It! is an exclusive Sun design and much attention has been paid to mechanical j refinement. The wheelbase is 116; inches, long enough to give easy rid- j ing and ample room in the body and | yet short enough to be handled easily j in city streets through congested traf- j flc. The motor is of the high speed, hi:gh | efficiency type, guaranteed to develop 50 horsepower on the block test. It is an L-head design with the valves located on the right side. The crank case is cast integral with the cylinder casting and the cylinder head is re movable. The motor is exceedingly simple and compact yet readily acces sible. The manufacturers state that it has been their aim to design a car that would operate economically even when the lowest grade of gasoline is used. Both the intake manifold and the hot air connection are cast in tegral with the cylinder casting In or der that the full benefit may be de rived from the heat of the motor. A 20-gallon gasoline tank is located at I the rear of the chassis and gasoline is | fed to the carburetor by the Stewart I vacuum system. The Rayfield car i buretor, so well known for its econ- I oray and dependability is standard equipment. i «. Th e. Y alves are large in diameter, the pistons are very light, • and the three bearing crankshaft is balanced by curving the webs in such a man ner as to scientifically distribute the weight. These features permit the motor to operate at exceedingiv high speed without vibration. An exclusive Sun design "dual ejector" exhaust manifold is used. It is divided into two divisions which al though connected give the effect of two independent manifolds as the ex haust gates from the three front cylinders are handled independently or the three rear cylinders. These gases are separated by a web that is cast within the manifold outlet. A slight web is also cast at £ach cylin der division In the manifold, which guides the gas in the right direction, thereby preventing it from causing a back pressure on the other cylinders Purthermore. the act of the g'as rush ins by the openings at high speed in the direction of the outlet causes a slight vacuum or suction. In short, the manifold construction is such as to not only overcome back pressure but really aid in perfectly scavenging the cylinders. The valve operating mechanism is located within the c-rankcase where it Is constantly subjected to a spray of oil. which prevents wear, and makes the working parts exceedingly quiet. A yery effective combination, conl sta.nt level splash and force feed lu brication system is employed. The oil pump is of the plunger type and Is operated from the camshaft. The main bearings and lower connecting rod bearings are die cast. Natural circulation cooling svstem. Water circulates entirely around the cylinder barrel and the valve seats. o£ « ' n ' e * an
