Passenger car motor oil is made from a combination of base oils which consist of additives like detergents, dispersants and viscosity index improvers. These substances are obtained from petroleum-based hydrocarbons which are vital for the lubrication of the internal combustion engines (ICE).
"These are known as viscosity modifiers or viscosity index improvers."
This can be caused by insufficient addition of viscosity index improvers (or viscosity index modifiers) [21].
In its initial phase, the facility will produce down-sheared and functionalized polymers for use as viscosity index improvers.
