Summary:Extra heavy lube base stocks are separated from heavy lube oils with a polar solvent in an amount sufficient to form a first light phase and a second heavy phase. The phases are then separated and the solvent is removed from the second heavy phase to yield an extra heavy lube. L'invention concerne des huiles de base extra-lourdes qui sont séparées des huiles lubrifiantes lourdes au moyen d'une quantité de solvant polaire suffisante pour former une première phase légère et une seconde phase lourde. Les phases sont alors séparées et le solvant est retiré de la seconde phase lourde pour créer un lubrifiant extra-lourd.
