Date Feb. 23, 1989.Used oils, especially used lube oils, after rough filtering are mixed with an aqueous solution of water glass and an aqueous solution of polyalkylene glycol while stirring at elevated temperature, the obtained mixture is allowed to settle, the settlings are separated, and water and light ends are removed from the oil phase by distillation. The thus obtained dry oil phase may be subjected to adsorptive filtering either direct or through a per se known treatment with dispersed sodium and may finally be fractionated by distillation.
