Homo- or co-polymers derived from one or more alpha-olefins having a number average molecular weight of up to 15,000 and an isotacticity of 75% or greater, and their use as Cold Flow Improvers in crude, fuel or lubricating oil.

Polymers and additive compositions

The invention is directed to a method of enhancing the low temperature flow properties of fuels comprising adding to the fuel a heated additive concentrate comprising: (A) at least one nitrogen-containing derivative of carboxylic acid, (B) an organic acid, and (C) at least one other flow improver, wherein the concentrate is heated to at least about 35.degree. C.

Low temperature enhanced distillate fuels

Friction modifier additives useful in power transmission compositions, particularly automatic transmission fluids, is disclosed. The additive comprises Component-1 alone formed by condensing a polyamine, such as tetraethylene pentamine, with an aliphatic mono acid, such as isostearic acid, or a mixture, and/or salt, of Component-1 and a Component-2 wherein Component-2 is an acid ester formed by reacting a heterodialkanol such as thiobisethanol and a hydrocarbyl substituted dicarboxylic acid or anhydride, such as octadecenyl succinic anhydride.
