John Smith is a character whom every motorist should welcome. He it not selfish; rather he is a motoring martyr, a chap willing and glad to have exploited, in an interesting way, his experiences for the benefit of the other 10,000,000 or more members of the motor clan. nor too lean it is necessary to use a radlator front covering in cold weather, to use yeheated air for the uretor in codl and cold weather have a thermostat to control culation of the water in the system. haps the next thing is to select There is a wide difference in gasoline, even in the straight variety, without adulterants. It varies so widely that I can buy one kind of gas for my engine for a few weeks and get a carbon knock far sooner than with another brand. Then when you consider the antl-knock fuels, you really have a choice of everything from the knocking type of 8as to the knockless type. “The extremes are likely to be dan- gerous. Of course, there I3 nothing to be gained by buying low-grade fuel that will foul up the cylinders, but, on the other hand, you should not use a concoction so doctored as to cause en- zine troubles. For efficlent operation of the engine there should be some- thing of an oil film on the cylinder walls even if the rings seem to wipe the walls clean. With some of the doctored gas, the operating temper- atures are so high as to Increase the possibility of scoring the cylinders, and of course much damage frequently is done to the valves. If You carry the anti-knock idea too far you may find yourself with a set of warped valves WVhen it comes to using anti-knock compounds, either as an addition to the regular gas that you buy or as a spedial fuel, there are several good rules to follow. In the first place, consult the charts issued by the manu- facturer of your car and see whether they recommend using the concoction you are planning to buy regularly. The second point is to start using the anti-knock fuel, if advised by the factory, after the engine is clean. Do not try to use it to clean out the en- gine. 'If you do that, you will stir up carbon particles in the cylinders, fre- quently causing them to lodge under the valve heads. The carbon that does blow out of the engine tends to clog up in the muffier, which results in loss of power. “Regarding the part that dust- laden air plays in forming what passes for carbon, it is true that clean air, filtered by any one of the many devices for this purpose, will help. The air cleaner alone, however, will not prevent the formation of carbon. Carbon accumulations vary with the attention and care given the motor."” Smith wasn't quite sure about these points, so T explained that letting the engine idle tends to form carbon. Then I pointed out the importance of having clean oil in the engine and the right grade so that an excess of it will not pass into the combustion chambers. Finally, T mentioned the importance of having good spark plugs, clean breaker points and a fully charged battery. “Carbon, you see, is more than a matter of dirt and residue,” I said. ““The amount accumulated depends to a large extent on who drives the car.” Next Week—Getting Home in Sec- ond. PLUGS MAY BE FAULTY. Point May Extend Too Far, Caus- ’ ing Preignition. Many car owners are discovering that any old spark plug will not do for their engines. The plugs must be not only good, but of the right size. This latter point is more than a mat- ter of outward appearance and thread size. If the points of the plugs extend too far into the combustion chambers of the cylinders they will become over- heated “and will cause preignition (knocking) and spark faflure. OF BUILDING wfL — The New Gardner Sport Sedan on the famous Eight-in-line chassis This will introduce the new Gardner Eight-in-line Sport ning. . . the Eight that whisks from a standing start to Sedan —such a brilliant per- former that you'll never be- lieve half the good things you’ve been hearing about it —until you actually take the wheel and try it out! This is the Eight you can drive from sunup to sundown without tiring—and without taxing the car. The Eight whose motor purrs so quietly you scarcely know it's run- you all the law allows in the flash of an eye...that sweeps over the road in such comfort you think you are actually coasting on air.

SPEED TESTS AT LAUREL TO POINT CAR OF FUTURE (Continued from Seventh Page.) road. Highways will be built to ac- commodate with safety those who will take curves at stralghtaway speeds, cars unable to operate fast enough to stay up on the curves being disquali- fled. The motorist hag seen the large, bulky automobile give way to the fléet car of short wheelbase, light welght and small dimensions. All this has been predicted by the events of the speedways, and the end is by no means in sight. Racing cars have become one-man cars, and there are many students of motor trends in America who predict that the modern cars of the speedway are a picture of the products of the motor car fac- tories of tomorrow. No one can stand spellbound at the forthcoming race without appre- clating the role played by the driver of each tiny car and without forming an entirely new conception of the growing importance of gray matter in the performance of cars. In the hands of less skilled drivers few of these cars could delives the goods that are stored up in them. This ties up with the idea that the next big step in motor development i8 in the better use of the latent power and ability of the modern cars. Get More Out of Car. It s not unusual for any of the star drivers to start with a certain machine early in the season and gradually get better results from it. As a better understandmg of the car comes its driver forces it forward to new high levels of speed and endur- ance. This is not always brought to the attention of the race devotee by reason of the fact that after break- ing records a driver will often run his next race over a slower or more troublesome track. He will not seem to be making any headway in the use of his vehible, yet the cold facts show that he is combining brain with steel to overtop his former records. It is expected that when De Paolo, Bob McDonough, Tommy Milton and others of the speed kings already an- nounced for the Laurel race October 24 break their most recent records thousands of automobilists will go back to their cars fully convinced that it is up to them to get more out of what the car manufacturers have provided. Motordom follows speedom. The iime is not far distant when, without the slightest change in ca# construc- tion, the average driver will be able to drive faster, stop quicker, climb hills to better advantage and avoid danger. The speedway predicts it. And the speedway is seldom wrong.
