Oil Pressure Gage
The oil pressure gage
shows the engine oil
pressure in psi (pounds
per square inch) when
the engine is running.
Canadian vehicles indicate pressure in kPa
(kilopascals). Oil pressure may vary with engine speed,
outside temperature and oil viscosity, but readings
above the low pressure zone indicate the normal
operating range.
A reading in the low pressure zone may be caused by
a dangerously low oil level or other problems causing
low oil pressure.{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would not
be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle. However, if it is going to
be 0°F (–18°C) or above and SAE 5W-30 is not
available, you may use SAE 10W-30.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 20W-50.
Oils meeting these
requirements should also
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certi ed by the American
Petroleum Institute (API).
