SERVICE AND MAINTENANCE
Oil viscosity
Incorrect viscosity oil can shorten engine life under
normal use. SAE 0W-20 will provide good fuel
economy and engine protection.
Turbocharger Operating Tips
In order to maximize the efficiency and operation
of your vehicle, the following points should be
observed:
1. Oil change and filter replacement every
10,000 miles/16,000 km, or at a time interval
based on the type of driving and conditions as
detailed in your Owner’s Manual. You should
maintain a record of these services (repair
order receipts).
2. Do not use engine oil additives as they may
adversely affect the engine.
CAUTION
Never race the engine immediately after
starting. Oil flow may not reach some
lubricating points fast enough to prevent
turbocharger damage.
Before switching off the engine, let it operate
at idle for a short time to allow the spinning of
the turbocharger compressor’s turbine vanes to
slow. After hard driving, this idle time should last
a couple of minutes, during which the vanes will
slow and the compressor will cool down while
still receiving oil lubrication. If the turbine vanes
are spinning at high speeds when the engine is
switched off, there is a great risk of heat damage
and/or turbine seizure due to lack of lubrication. Do not race the engine just prior to switching
off!
