Abstract
A hybrid grease is provided having low coefficients of friction and high wear protection which is employable over a wide temperature range. The hybrid grease includes a combination of a grease based on a silicone oil in conjunction with a grease based on synthetic hydrocarbon oils, mineral oils or polyglycols. The hybrid grease may especially be used to lubricate joints in vehicle parts based on plastic-steel pairings.
