Single Grade Oils
WARNING: This page does not describe the selected car, but rather 250 other vehicles, including the 2006 BMW Z4, 2006 BMW X5, 2006 BMW X3, 2006 BMW M6, and 2006 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
A single grade viscosity oil has a limited temperature/viscosity range compared with multigrade oils. Due to the limited temperature/viscosity range of these oils they are no longer used in BMW engines and thus no longer listed in the BMW Engine Oil Temperature/Viscosity Table.
