    摘要: A dilurea grease composition contains a lubricant base oil and a thickener. The thickener essentially consists of a mixture of at least two diurea compounds each being represented by the following general formula (I) of: ##STR1## wherein R.sub.1 is a difunctional aromatic hydrocarbon residue, and A and B each stands for an amino group represented by the general formula (II) of R.sub.2 --NH--(where R.sub.2 stands for a cyclohexyl group, a group derived from cyclohexyl or an alkyl group) or an amino group represented by the general formula (III) of ##STR2## (where R.sub.3 R.sub.4 each stands for cyclohexyl group or a group derived from cyclohexyl). The ratio in percentage of the numbers of the amino groups (III) to the total numbers of the amino groups (III) plus the amino groups (II) ranges from 1 to 50%. The ratio of the numbers of the amino groups (II) wherein R.sub.2 is a cyclohexyl group or a group derived from the cyclohexyl to the numbers of the amino groups (II) wherein R.sub.2 is an alkyl group ranges from 174 to 4/1.
