Abstract
The present invention relates to methods of fueling an internal combustion engine, and composition, that provide improved nitrogen-free detergency in the engine, particularly in the area of injector deposit control. The present invention also provides methods of providing both improved detergency and improved corrosion inhibition, while avoiding compatibility problems with fuels and/or while limiting the amount of nitrogen delivered to the fuel from the deposit control additive.
