Oil additive compositions exhibiting reduced haze containing polymeric viscosity index improver. |
摘要 |
Oil compositions comprising a lubricating oil and oil-soluble hydrocarbon polymeric viscosity index improvers such as ethylene-propylene copolymers are substantially haze-free when said compositions contain an anti-hazing effective amount of a hydrocarbyl substituted succinic acid. The invention also relates to the process for preparing said compositions.
