When this condition develops a quan- tity of the fuel forces it's way down past the rings into the reservoir, and is. of course, wasted. The owner who has reason to suspect this condition should try fitting some of the leakproof piston rings of patent construction, de- signed to correct just this fault Thls same condition is sometimes produced by the use of lubricating oil or 100 light body The oil is thinned by the heat present under running condi- tions and lacks the viscositp to make perfectly gas tight seal at the piston As a result the fuel forces it's way past the rings and into the reservoir. Then there is the possibility of utiliz- ing heavier and cheaper grades of fuel Most modern cars will run on the cheapest grade of gasoline and even to a mixture of gasoline and kerosene, in the proportion of one gallon or the latter to three of the former. ObYiou1y certain adjustments in the carburetor will have to be made. perhaps by the service station. but the saving in cost between gasoline at 25 to 35 cents and kerosene at 13 cents per gallon justi- fies the trouble If the owner desires to try out one of the kerosene car buretors or other devices for using this heavier fuel we would suggest his get ting one that is sold on approval or with money back guarantee. 10 that he may find out if the apparatus works satisfactorily on his vehicle before he makes the final purchase.
 We spoke before of power losses in the engine, and this form of fuel waste is not confined to the power plant. For instance much power may be wasted at the clutch, if this part is not func- tioning properly. If the clutch slips excessively potential power is being lost and the fuel which produces it is being wasted. The cone clutch, with 
 with F'ullers earth or neatsfoot oil. or perhaps the spring tension requires adjustment In the dry disc clutch there may be gum on the plates or the springs may need attention. An oil disc clutch may have burned out one one of its plates, the spring pressure may be wrong or the lubricant may not be correctly diluted with kerosene.
 We touched cn the subject of lubri- cation before and we would again em- phasize the fact that wherever there IS a moving surface not thoroughly lubri- cated there is wasted power. Lubrica- tion must be copious, complete and correct if the full power producing value of the fuel consumed is to be obtained
 Then there is the question of tires. It is an unquestioned fact that power is wasted when the tires are operated underinflated, so that an excessive
 
 with the ground. Incidentally, while this practice. all too common among American motorists, wastes fuel, it also injures the tires, which is a verp ex- pensive form of waste. It is better to run the tires at a few pounds over the prescribed imitation point than @ few pounds under it. In addition every owner ought to have the alignment of his front wheels checked up once in four months. When the tires are run ming out of alignment. scraping movement is set up. which not only wastes power but wears out the tires very quickly The owner who cares anything for his pocketbook probably needs no hint as to the desirability of plugging all cuts in the rubber tread as soon as they appear.
 If the suggestions made above are conscientiously needed the result will be an appreciable saving for the indi- viduaI owners of motor vehicles and an enormous saving in our national re- sources Of motoring necessities, which were part of our equipment for wag- ing the recent war. The man who operates his car with real economy is not only benefitting himself, but Is performing a patriotic duty at a crisis in his country's history.
