Show IlLES Pffl 1ST EClfffil SPEED i For the edification of the speed monomaniacs mono-maniacs of Salt Lake and other towns, cities and rural communities, it is perhaps per-haps well to tell them that the conservation conser-vation of gas, that the United States mav more quickly win the war, demands that they keep their speedometer needle : hovering around tlte twenty-mile an , hour mark. Back in the good old days, when Olds was young and Ford but a youth, it was a standard no pun intended joke of how the auto m obi list arrested for fast driving maybe ten miles an hour ottered as nu excuse for his unseemly unseem-ly speed the necessity for it because his . iuiiiuiii;e was almost all i:one and he was anxious to reach a supply station before j it was completely exhausted. Xow I comes a believer in this theory, and writes to a daily newspaper setting; forth the claim that more miles to the; gallon (less quantity to the mile) can ! be obtained by driving a car at forty-: five miles per hour than by doing the same tiling at twenty-five miles per hour. No one will deny that extremes in speed, either high or low, are productive produc-tive of high fuel bills. Practice has demonstrated that around twentv miles per hour is the most economical rate of speed. The need of keeping the cylinder interiors hot enough to insure full e.:s expansion tends to make materially lower speeds uneconomical, while at higher speeds the swaying and jars of tiie banl-driven car all rapidly increase the work required of the engine; and more power means ; more fuei, with a scalier mileage iu the! end. Furthermore, it will be found that, an average speed of around twenty j mill's per hour, without, any regard i wliat-ocvrr as to ihe co-'t ojf maintain-' ing il, means saving m.'i.iy tliinti-' be- sides gasoline, jyuur nerved among them. |
