ADVANTAGES OF LEAD IN GASOLINES FOR EUROPEAN CARS--THE LEAD ROAD BONUS

In recent years, several programs have been conducted at the Ethyl Research Laboraories in Detroit, some in cooperation with a major oil company, to measure the value of lead antikoncks in fuels for European cars. These heretofore unpublished studies show: 1. A positive lead road bonus. 2. Tetramethyllead (TML) is more effective than tetreathyllead (TEL). 3. The lead road bonus increases with engine operating severity. The lead road bonus is defined in broad terms as a combination of three effects - lead-in- fuel, fuel sensitivity, and engine deposits. The engine- deposit effect is not of major significance in European cars.
