| Zusammenfassung: | The compositions comprise a base oil and an additive selected from a multifunctional olefinic copolymer viscosity index improver with dispersant properties, Mg sulfonate and mixtures thereof and optionally and preferably a polymethacrylate demulsifier and high molecular weight dispersant. The lubricant compositions have particular utility in engines fueled by alcohol or gasoline/alcohol blends. Emulsion stabilising additives comprising the above components are also claimed. |
