Superior thermal stability
WARNING: This page does not describe the selected car, but rather 180 other vehicles, including the 2014 BMW i8, 2014 BMW i3, 2014 BMW Z4, 2014 BMW X6 M, and 2014 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.
The synthetic based oil resists thickening at very low ambient temperatures providing improved flow, lubrication and less internal engine resistance during cold starts.
Under high heat conditions, the oil resists thermal breakdown/shearing which causes a loss of lubrication quality compared with conventional oils.
