For information on the correct engine oil quality and viscosity, refer to the
following:
Gasoline Engine Oil Quality
Oils of the proper quality for the vehicle can be identified by looking for
the Saturators symbol. The STARBURST symbol indicates that the oil has been certified
by the American Petroleum Institute (API), and is preferred for use in gasoline engines.
Diesel Engine Oil Quality
Oils designated as API CH-4 or CG-4 are best. The CH-4 or CG-4 designations
may appear either alone, together or in combination with other API designations, such
as API CH-4/SJ, CG-4/SH or CH-4/CG-4/SJ.
These letters show American Petroleum Institute (API) levels of quality.
Important: Oils that don't have one of these designations (CH-4 or CG-4) can cause engine
damage which is not covered by the warranty.
Gasoline Engine Oil Viscosity
Engine oil viscosity (thickness) has an effect on fuel economy and the cold-weather
operation (engine starting and oil flow). Lower viscosity engine oils can provide
better fuel economy and cold-weather performance. However, higher temperature weather
conditions require higher viscosity engine oils for satisfactory lubrication.
SAE 5W-30 is best for your vehicle. However, use 10W-30 if the outside temperature
is higher than 18° C (0° F). Do not use other viscosity oils,
such as SAE 20W-50.
Notice: Using oils of any viscosity other than those recommended
could result in engine damage. When choosing an oil, consider the range of
temperatures the vehicle will be operated in before the next oil change.
Then, select the recommended oil viscosity.
Important: If your vehicle is operated in an area where the temperature falls below -29°C
(-20°F), consider using a SAE 5W-30 synthetic oil or a SAE 0W-30. Both will
provide easier cold starting and better protection for the engine at extremely low
temperatures.
Diesel Engine Oil Viscosity
Important: As shown in the viscosity chart, SAE 15W-40 is best for your vehicle. However,
you can use SAE 10W-30 if it's going to be colder than 0° C (32° F)
before your next oil change. When it's very cold, below -18° C (0° F),
you should use SAE 10W-30 to improve cold starting. SAE 30 may be used at temperatures
above freezing, 0° C (32° F).
These numbers on the oil container show its viscosity, or thickness. Do not
use other viscosity oils such as SAE 10W-40 or SAE 20W-50.
Chassis Lubrication
Notice: Do not lubricate the parking brake cables. Lubrication destroys the
plastic coating on the cable.
