[Properties of synthetic oils] Thanks to the oil’s high viscosity index, the viscosity is affected less by temperature changes than with normal mineral oils. [Resulting benefits] 
The oil does not become too thick when cold, or too thin when hot. This reduces engine wear at temperature extremes. Less viscosity modifier is needed, which leads to lower levels of deposits.
