Fliers of the Land and Air Depend on AT BRAINARD FIELD—Hartford A few weeks ago seven huge Martin Bombing Planes landed at Brainard Field en route to Mitchel Field, New York. These planes must have the best gas obtainable and your atten- tion is called to the DIXIE TRUCK in the act of filling the fuel tank of one of the planes. Up in the clouds, fighting head winds blowing twenty- five miles an hour and more these planes must be sure of DEPEND- ABLE POWER. The gas must be of the kind that literally LEAPS half- way to meet the Spark. The answer is DIXIE GAS. —— P E At Charter Oak Park With The Speed Demons . Summary of Charter Oak Auto Races Time Trial, One Mile, Won by Ralph De Palma 51 2/5 Seconds, Used DIXIE GAS. T!lree-Milc—Won by Ralph De Palma, 1 'Minute, 43 2/5 Seconds; Used DIXIE GAS.

It would seem that the fuel used by De Palma, Ira Vail and “Red” Shafer to speed their racing cars on, to send them hurtling towards that checkered flag with victory in their grasp through the bullet-like travel developed, would be the kind of gasoline the ordinary motorist could use to the best advaptage since all he wishes is a fair rate of speed *but with the power there when he needs it. And you must have the fuel that does its part, the gasoline that “MEETS THE SPARK HA LFWAY.” to “bring home the bacon” — and | DD(E; GAS has never failed to To prove to the public that DIXIE MOTOR OIL is far superior to ordinary brands of oil, we will give absolutely FREE a coupon book good for FOUR QUARTS of DIXIE MOTOR OIL with every purchase of 5 g \ allons or more of DIXIE GASOLINE Saturday, Sept. 15,23, One Day Only 33 MAIN STREET, NEW BRITAIN DIXIE GAS is on sale at scores of filling stations through- out New England.
