RECOMMENDED LUBRICANTS AND CAPACITIES

To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.

*

3

If the API SM engine oil is not available, you can use API SN or above.

*

4

If the ILSAC GF-4 engine oil is not available, you can use ILSAC GF-5 or above.

Recommended SAE viscosity
number

Engine oil viscosity (thickness) has an
effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosity
engine oils can provide better fuel
economy and cold weather perform-
ance;

however, higher viscosity

engine oils are required for satisfacto-
ry lubrication in hot weather. Using
oils of any viscosity other than those
recommended could result in engine
damage. When choosing an oil, con-
sider the range of temperature your
vehicle will be operated in before the
next oil change. Proceed to select the
recommended oil viscosity from the
chart.

VEHICLE IDENTIFICATION NUMBER (VIN)

The vehicle identification number
(VIN) is the number used in register-
ing your vehicle and in all legal mat-
ters pertaining to its ownership, etc.
The number is punched on the front
side wall of the engine room.

The VIN is also on a plate attached
to the top of the dashboard. The
number on the plate can easily be
seen through the windshield from
outside.

The vehicle certification label
attached on the driver’s side center
pillar gives the vehicle identification
number (VIN).

The tire label located on the driver's
side center pillar gives the tire pres-
sures recommended for your vehicle.

The engine number is stamped on the
engine block as shown in the drawing.

The refrigerant label is located on
the underside of the hood.
