CONSERVE GASOLINE
 BY ELIMINATION IF
 UNNECESSARY WASTE

The present situation in the motor fuel field is such that all of us must bend every effort to conserve gasoline in every possible way, not only by obviating actual waste but by getting the utmost out of the gas that we do use. There is no shortage in most sections of the county, but there may easily be one if we are not all careful in our use of this now precious fluid.
 Economy, like charity, begins at home. If we can impress on the indi- vidual car owner the fact that every fuel waste must be multiplied by S,000,- 900 to arrive at the grand total, he may see why the spoonful or so of gas he wastes. per day is really important. If each of the S00O,0O0 car owners in the country wastes half pint of gaso- line per week the total amounts to 500.- 900 gallons each week, or 21,000, 900 gallons per annum. That is why each of us must do his individual best if we are to avoid a shortage of motor fuel in the near future.
 The first point of attack in the cam paign to cut down fuel consumption is the carbureter. It has been said that the average car owner runs his engine on a fuel mixture nearly twice as rich in gaosline as it needs to be; in fact the engine will give it's best work on a mixture as lean as possible. Practically all modern carbueters have a wide range of adjustment, so that all the air needed may be got by adjusting the instrument itself It is a very simple matter to set the carbueter for more and more air until the mixture is too thin for proper operation and then turn back until the engine is running smoothly again with maximum air in take. This question of fuel mixture
 is a very important one. since. if American motorists habitually ran on a mixture that was twice as rich as need be, the consumption of gasoline would be just twice as great as the actual needs. In the interest of patri- otism then, let every car owner make sure that he is using a mixture just as lean as is consistent with proper opera ton. Moreover, the engine may actually run better on the leaner mixture, to say nothing of the reduction of carbon deposits that will ensue.
 Having adjusted the carbueter to supply the proper fuel mixture the en tire fuel system ought to be gone over
 Dirt in the pipes, rust in the strainers | or foreign matter in the gasoline tank help cut down the efficiency of the whole engine. Leaks in the system | should be carefully hunted down and | eliminated. This means not only ac-
 tual leaks but power leaks, for wasted l power means additional consumption
 of fuel to make good the deficiency. In this category will be found muf- | fer clogged with soot, resulting in back pressure, which cuts down the eff
 ciency of the engine Carbon deposits | in the cylinders cause waste of power
 and excessive consumption of fuel Il will be noted that this problem of fue waste is cumulative in effect. If ths | fuel mixture is too rich, it not only
 wastes fuel directly, but produces car | bon deposits in the cylinders and 500 | in the muffler, which causes further
 useless dissipation of the fuel energy | In connection with carbon deposits, f
 might be desirable to install one of the vaporizing devices, which inject water vapor into the combustion chamber
