| EVERY CAR OWNER NEEDS THIS NEW DEVICE Gallons of wasted gasoline (petrol)! Leaky and sticky valves! Undue friction and wear! All of these things drain enormous sums from the pockets of motorists each year. But now, thanks to the new Radiant FUEL SAVER, these expenses can be kept to a minimum. Every motorist, whether his automobile be brand new, or an old one, owes it to himself to put a FUEL SAVER on his car! SAVES EXPENSIVE REPAIR JOBS BY KEEPING MOTORS RIGHT! MIXES 96% AIR WITH GASOLINE FOR (Petrol) REAL ECONOMY & PERFORMANCE Automotive engineers unanimously agree that improper or inadequate lubrication is the cause of most motor repairs. These engineers heartily endorse top oiling. In fact, leading motor companies recommend that a top oiler be installed on new cars. In the Radiant FUEL SAVER you not only enjoy the benefits of a highly efficient top oiler, but you can obtain greatly increased gasoline (petrol) mileage as well. How does the FUEL SAVER work? Simply this. A control near the motor fan closes whenever the motor speed reaches the point at which you want the FUEL SAVER to start working. Around 20 to 25 miles per hour is the most logical speed. The instant this control closes, air is drawn into an oil container, where a very fine mist of air and oil is created. This mist then passes through to the manifold—the air leaning the fuel mixture and increasing mileage—the oil spraying valves, cylinder walls, etc., forming a protective film thereon. FREES STICKY VALVES! REDUCES CARBON! REDUCES FRICTION REDUCES WEAR! SAVES GAS The gas-saving principle of the Radiant FUEL SAVER is based on the procedure of adding a larger quantity of air to the gasoline (petrol) thus making the mixture leaner. Understand that this extra air is not added when your motor is started, or while idling. The FUEL SAVER does not begin to function until your motor is operating at a speed of from 20 to 25 miles per hour, or at whatever point you wish to set it. Therefore, the performance of your car or truck is not affected in any way when starting, going up hill at low speed, etc. On the other hand, you will be surprised to see the extra “zip” of your car when the FUEL SAVER does cut in—and how much longer each tankfull of fuel will last! A nice feature of the FUEL SAVER is that it can very easily be attached to any car or truck without disturbing a single part thereon. Any average motor owner can install it in a short time. For those who do not care to install this device themselves, any garage mechanic can do so in just a few minutes. INCREASES COMPRESSION SAVES MOTORS! ADDS SPEED! ADDS POWER! SAVES OIL | ||
