Abstract: Computerized method, system and computer-readable medium are provided for ordering and billing goods and services in connection with the goods. Each embodiment is customized to meet the individualized needs of users in respective market segments by enabling ordering of packages of the goods. The method allows providing a user-interface to each user configured to enable the user to define at least one package identifier associated with a respective set of goods and/or services of interest to each respective user. The method further allows populating a database with at least one parameter comprising respective model identifier and service code for each good and/or service associated with each respective package identifier. The database is accessed in view of each defined package identifier to retrieve the at least one parameter for each respective package identifier.

Abstract: Mannich reaction products are disclosed as additives for hydrocarbon fuels. The Mannich reaction products are added to a low sulfur content, middle-distillate, compression ignition fuels in an amount effective to improve the lubricity of the fuel, typically within the range of from about 10 to about 1000 parts of additive per million parts fuel (ppm w/w), and thereby reduce the wear occasioned upon the fuel pump. Compositions comprising a hydrocarbon fuel and the reaction product are also disclosed.

Abstract: This invention relates to low sulfur fuel compositions which exhibit improved lubricity compared to the low sulfur fuels alone. The low sulfur fuel compositions contain a middle distillate fuel having a sulfur content of 0.2% by weight or less, a carboxylic acid amide and at least one member selected from the group consisting of cold flow improvers, ashless dispersants, and mixtures thereof.

Abstract: Low sulfur content fuel compositions containing additive compounds are described which exhibit improved lubricity. The additive compounds include a carboxylic acid substituted by at least one hydroxyl group, derivatives of the carboxylic acid substituted by at least one hydroxyl group, and an ester which is the reaction product of a carboxylic acid which does not contain any hydroxy-substitution in the acid backbone and an alkanolamine.
