The copyrighted program created by the Rio Grande the Oil Company. Please call on all cars, essential all cars, broadcast 150. Invest, get a fire at 2124 Brandon Street. That's all frozen. Blooded listeners everywhere, thrilled to these true exploits of crime detection.

We are knackered for you on Rio Grande's radio program calling all cars. You are able to feel that you are a part of this relentless war on crime. Every time you hear a siren shriek, every time you hear a police smoke a roar, your heart beats a little faster.

And while you cannot actually take part in police activities, you can experience every day at least a part of their thrills. You can use in your car exactly the same Rio Grande crack gasoline that starts police cars so quickly.

The same even burning gasoline that speeds them so swiftly through dense city traffic. The same powerful gasoline that lifts them so easily up steep hills without motor pings or shifting of gears. In other words, you can have police car performance.

Just drive into any re-aggrandi-independent service station tomorrow and save filler up with cracked gasoline. Before night, you'll know why so many city and county police cars, fire engines, ambulances, and other emergency equipment specify re-ogrammed the cracked gasoline in preference to any other brand.

We guarantee you'll get a greater thrill out of using Rio Grande Crac's gasoline as you get out of listening to Pauling Hall cars. Use 10 gallons of police car performance and you will never again be satisfied with ordinary sluggish gasoline.

Remember, only Rio Grande gives you gasoline refined for the patented Sinclair cracking process. Try a thankful tomorrow at any independent service station displaying the big Rio Grande design. Tonight, in commemoration of the National Fire Prevention period, we have a guest in our studio Chief Ralph J. Scott of the Los Angeles Fire Department, who will speak to you.
