Abstract: A process for preparing alkylhydroxybenzoate detergent-dispersant additives having low sulfur content and high TBN is described. The alkali metal alkylhydroxylbenzoate, alkaline earth metal alkylhydroxybenzoate and overbased alkaline earth metal alkylhydroxybenzoate reaction products described have a sulfur content in the range of from about 0.1 to 1.2 wt % are effective anti-corrosive detergent-dispersant additives in lubricating oil compositions.

Abstract: A distillate fuel composition having low foaming characteristics and process for making the composition is described. The composition and process uses Fischer Tropsch distillates to reduce the foaming in distillate fuels. The use of Fischer Tropsch distillates to control foaming in distillate fuels reduces or eliminates the need to use silicon anti-foam agents. A preferred composition comprises at least 20 vol. % of a petroleum derived distillate having a foam vanishing time greater than 20 seconds; and at least 5 vol. % of a Fischer-Tropsch derived distillate having a foam vanishing time of less than 15 seconds; where the resulting distillate fuel blend has a foam vanishing time of 15 seconds or less in the absence of an antifoam additive.
