Show INFERIOR FUEL IS HARMFUL TO MOTOR a According to J. w. Cox, manager of the truck department of the Randall-Dodd Randall-Dodd Auto company, local O. M. C. distributers, dis-tributers, G. ML C. interest does not cease when an order has been received or the truck placed In the customer's hands, but the G. M. C. makers and the dealers always bear in mind the many suggestions to aid in helping the owner to receive tho highest point efficiency, and to prolong tha life of his motor truck. In following out this statement Mr. Cox submits the following service bulletin from the G. M. C. Truck company, which Is not only of Interest to the users of G M. C. trucks, but Is an important lesson to the man using any other make of truck as well. 'Experience has taught us." runs the bulletin, "that there is todav confronting the commercial vehicle a problem which bears directly on the maintenance and cost of operation this is the inferior fuel and its harmful effects upon the motor The present low gravity gasoline Is practically prac-tically a high-grade kerosene and very difficult to vaporize. We have learned from recent tests which were made from motors of different makes that a certain percentage of the gasoline which is drawn Into the combustion chamber Is not consumed con-sumed by the explosion, but passes down the cylinder wall Into the crank case, causing the engine oil to lose its luhrloat- inff efficiency, which results in the following follow-ing trouble: "Hard starting. "Loss of power. "Excessive wear on pistons, piston rinps, cylinders and aU crankshaft bear- . ings. "Crankshaft out of round. "The kerosene has a tendency to loosen the carbon in the cylinder head, which mixes with oil and makes a carbon lapping lap-ping compound, increasing the wear already al-ready caused by the parte running without with-out proper lubrication. The only remedy to overcome this difficulty is to frequently frequent-ly change the engine oil." |
