A series of stable colloid lubricant additives have been evaluated for their influence on vehicle fuel economy through modification of engine friction. The SAE J-1082 procedure was used to determine fuel consumption in tests conducted in a seven vehicle fleet exercise which showed encouraging improvements in fuel economy, especially in the SAE Urban cycle. In addition, an extended dynamometer test was conducted on the most promising colloid additive system. After 100 hours of test at 55 mph (road-load), fuel consumption was reduced by approximately 2% and engine friction was inferred to have been reduced by more than 10%.
Engine oils treated with these stable colloid additives hold the promise of effecting important fuel savings over the total existing vehicle population within a minimum time frame.
