Abstract: The presently claimed invention is directed to novel polyesters which are obtainable by reacting a mixture comprising at least one C8-C20 Guerbet alcohol, at least one aliphatic or cycloaliphatic dicarboxylic acid and at least one polyol with a hydroxyl functionality in the range of ?2 to ?6 and the use of these polyesters as a component of lubricating oil compositions.

Abstract: Lubricant composition comprising a dicarboxylic acid ester component which is formed from a dicarboxylic acid selected from the list consisting of adipic acid, phthalic acid, pimilic acid, suberic acid, azelaic acid and sebacic acid, and mixtures thereof and a branched aliphatic alcohol R—OH which is defined according to the following formula (I) whereas q, r and s are defined as follows, q+r=4 to 9, s=0 to 5, q=1 to 8, and r=1 to 6, and an ethylene-propylene copolymer.

Abstract: Suggested is a method for enhancing energy efficiency of engines by applying to said engines a lubricant composition containing (A) carboxylic esters derived from the reaction of mono-, di- and/or poly alcohols with mono- and/or dicarboxylic acids, together with an additive blend (B) comprising at least two different additives (a) and (b) together, whereby compound (a) is selected from dithiophosphates, and compound (b) is selected from alkylated phosphorothionates, on condition that the total amount of the additive blend (B) is below 0.1 wt %, calculated on the weight of the whole composition.
