Gegenstand der Erfindung sind Schmiermittel auf Polyolbasis für Zweitakt-, Viertakt- und Rotationskolbenmotoren bei Betrieb derselben mit Kraftstoffen, die Alkohol(e) und/oder Nitroalkan(e) und/oder Propylenoxid enthalten, wobei das Schmiermittel den Kraftstoffen zugesetzt ist und/oder sich in einem getrennten Schmiermittelkreislauf befindet und wobei die Polyole zu mindestens 40 Mol.-% aus Propylenoxideinheiten bestehen. The polyol-based lubricants for two-stroke, four-stroke and rotary-piston engines operated with fuels containing alcohol(s) and/or nitroalkane(s) and/or propylene oxide, are added to the fuels and/or are in a separate lubricant circulation, the polyols consisting to the extent of at least 40 mol % of propylene oxide units.
