Abstract: An additive combination for improving the cold flow properties of distillate fuels comprises a combination of:(A) a distillate flow improver which is an ethylene containing polymer, preferably a copolymer of ethylene with unsaturated esters, e.g. vinyl acetate;(B) a hydrocarbon polymer of C.sub.2 to C.sub.30 olefin of number average molecular weight of 10.sup.3 to 10.sup.6 or derivatized version thereof, for example copolymers of ethylene and propylene, or polyisobutylene, which are used as lubricating oil V.I. improvers; and(C) a polar oil soluble compound which includes amides, salts, carboxylates, sulfonates, sulfates, phosphates, phenates and borates, having hydrocarbon solubilizing groups, for example salts and amides of polycarboxylic acid such as phthalic anhydride reacted with hydrogenated secondary tallow amine.

Abstract: Three component additive combinations for improving the flow of distillate fuel oils comprise(A) a conventional distillate fuel flow improver(B) a lube oil pour depressant and(C) a polar compound other than certain specified nitrogen compounds which acts as an anti-agglomerant for wax particles in the fuel oil.

Abstract: Metal phenates especially overbased phenates are prepared by reacting a basic metallic compound with a mixture of an alkyl phenol and an alkyldihydroxybenzene. The products are useful as lubricant additives with improved antirust properties, and when overbased, with higher basicity and lower viscosity.
