Haze free oil additive compositions containing polymeric viscosity index improver and process for producing said compositions |
摘要 |
Oil compositions comprising a lubricating oil and an oil-soluble hydrocarbon polymeric viscosity index improver such as ethylene-propylene copolymers are substantially haze-free when said composition contains an anti-hazing amount of an oil-soluble strong acid containing a hydrogen dissociating moiety which has a pK of less than about 2.5, e.g. a C25 to C70 hydrocarbyl substituted sulfonic acid. The invention also relates to the process for preparing said compositions.
