An additive composition of boronated phenolic antioxidant and anti-haze diol capable of complexing with boric acid as well as organic material protected by the additive composition. A hydrolytically stable additive composition comprising a boronated phenolic antioxidant and a diol member capable of reacting with boric acid formed as a hydrolysis product to form a stable ring structure soluble in a substrate. The additive composition prevents or cures a haze caused by hydrolysis.

Haze-free boronated antioxidant

The viscosity index and wear inhibiting properties of lubricating oil are improved by adding an effective amount of a 20,000-300,000 molecular weight olefin copolymer to which are grafted di-C.sub.1-20 alkyl dithiocarbamate groups.

Lubricating oil composition containing a dialkyl

A lubricating oil dispersant is made by grafting an alkyl methacrylate or acrylate and maleic anhydride onto a Bright Stock mineral oil backbone using a free radical generating catalyst and then reacting the product with an amine to form amide or imide groups.

Fuel consumption of an internal combustion engine being operated on a normally liquid hydrocarbon fuel of the gasoline boiling range is reduced by the addition to the fuel of a friction-reducing amount of a sulfurized fatty acid amide, ester or ester-amide of an oxyalkylated amine.

Friction modifier for gasoline

An anti-wear compression ignition fuel for use in diesel engines comprising (1) a monohydroxy alkanol having from 1 to 5 carbon atoms, (2) an ignition accelerator and (3) a wear inhibiting amount of a dimerized unsaturated fatty acid and an ester of a phosphorus acid.

Lubricant corrosion inhibitor

Polyesters suitable for use as lubricant additives are prepared by reacting a di-carboxylic acid or anhydride having a branched chain alkyl or alkenyl substituent containing at least 30 carbon atoms with a compound having the formula: ##STR1## wherein R and R.sup.1 are specified substituents which between them possess from 2 to 6 free hydroxyl groups. Lubricating compositions containing these polyester additives are also described.
