The present invention provides a rheology control agent of oil, which can impart a remarkably high elastic modulus with being sufficiently flowable as liquid by adding the same to the oil and it provides an oil composition having the greatly improved rheology characteristics. That is, the present invention provides a rheology control agent of oil, which is made from a polyether having monomeric units having the formula (I) and it provides an oil composition containing the rheology control agent and an oil: wherein R represents a hydrogen atom, a hydrocarbon group having 1 to 42 carbon atoms or a group of -(AO)m-R , R being a hydrocarbon group having 1 to 28 carbon atoms, A being an alkylene group having 2 or 3 carbon atoms, m being a number of from 1 to 100.
