BMW F 800 GS Rider's Manual page 65

Fuel attacks plastics, which
become dull or unsightly.
Wipe off plastic parts immediately
if they come into contact with
fuel.
Leaded fuel will destroy the
catalytic converter.
Use only unleaded fuel.
Make sure the ground is level
and firm and place the motor-
cycle on its side stand.
The volume of the tank can
be utilised to the full only
when the motorcycle is propped
on its side stand.
Open the protective cap.
Use the ignition key to unlock
the fuel filler cap and pop the
cap open.
Refuel with fuel of the grade
stated below; do not fill the
tank past the bottom edge of
the filler neck.
When refuelling after run-
ning on reserve, make sure
that you top up the tank to a
level above reserve, as other-
wise the sensor will not be able
to register the new level. If the
sensor cannot register the new
level neither the fuel-level read-
ing nor the range readout can be
updated.
