BMW Z4 M Roadster 2008 - Manual (Page 8)

Confirmation Stamp For 1200 Mile
Service
The engine in your Z4 M Coupe and Roadster is
a race-bred engine design which includes
increased power output and maximum engine
speeds compared to conventional BMW Z4
engines. The increased power output also
affects other major drivetrain components such
as the transmission and the rear axle differential.
The 1200 Mile Service requires changing the oil
in the engine and in both the transmission and
the differential.
Quality Certification I
For a detailed list of items inspected, refer to the
Quality Certification I form provided to the
Owner at time of delivery. A copy of the form is
on file at the selling BMW center.
Unscheduled Maintenance
Only use fuels advertised to have adequate
detergency and low alcohol content. Use of
fuels with insufficient detergent and/or excess
alcohol can cause driveability problems that
necessitate cleaning intake valves and fuel
injection valves, and, when applicable, adjusting
the engine idle. We suggest having this work
performed by your authorized BMW center, per-
haps while regular maintenance is performed.
Your BMW center can also recommend a gaso-
line additive that will provide sufficient deter-
gency. While this recommended unscheduled
maintenance is not required in order to maintain
the emission warranty, cleaning of intake valves
or, when applicable, fuel injection valves, or
adjustment of engine idle, necessitated by use
of inappropriate fuel, is not covered by warranty
because no defect in material or workmanship
or component failure is involved.
