Services
Following are explanations of the services listed in
Schedule I and Schedule 11.
The proper fluids and lubricants to use are listed in
Section D. Make sure whoever services your vehicle
uses these. All parts should be replaced and all
necessary repairs done before you or anyone else drives
the vehicle.
NOTE: To determine your engine's displacement and
code, see "Engine Identification" in the Index.
1. Engine Oil and Filter Change* -- Always use SH
or SG Energy Conserving I1 oils of proper viscosity.
The "SH" or "SG" designation may be shown alone
or in combination with others, such as "SH/CD" or
"SH, SG, CD," "SG/CD," etc. To determine the
preferred viscosity for your vehicle's engine (e.g.,
SAE 5W-30 or SAE low-30), see "Engine Oil" in
the Index.
If your vehicle has an Engine Oil Life Monitor, the
monitor will show you when to change the oil. See
"Engine Oil Life Monitor" in the Index.
