Explanation of Scheduled
Maintenance 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

Always use SH or SG Energy
Conserving I1 oils of proper
viscosity. The engine requires a
special oil meeting GM Standard

this GM Standard. You should
look for and use only an oil that
meets GM Standard GM4718M.
To determine the preferred
viscosity for your vehicle’s
engine (e.g.,
SAE 5W-30 or SAE
10W-30), see “Engine Oil” in
the Index.
Your vehicle has an Engine Oil
Life Monitor. This monitor will
show you when to change the oil
- usually between 3,000 miles
(5 000 km) and 7,500 miles
( 12 500 km) since your last oil
change. Under severe conditions
the indicator may come on before
3,000 miles
(5 000 km). Never
drive your vehicle more than
7,500 miles (12
500 km) or 12
months without an oil change.
The system won’t detect dust in
the oil..
So if you drive in a dusty
area be sure
to change your oil
every 3,000 miles
(5 000 km) or
sooner if the “Change Oil” light
comes on.

Chevrolet regularly sends its dealers
useful service bulletins about Chevrolet
products. Chevrolet monitors product performance
in the field. We then prepare
bulletins for servicing our products better.
Now, you can get these bulletins too.
Bulletins cover various subjects. Some
pertain to the proper use and care of your
vehicle. Some describe costly repairs.
Others describe inexpensive repairs
which, if done on time with the latest
parts, may avoid future costly repairs.
Some bulletins tell a technician how to
repair a new or unexpected condition. Others describe a quicker
way to fix your
vehicle. They can help a technician
service your vehicle better.
Most bulletins apply to conditions
affecting a small number of cars or trucks.
Your Chevrolet dealer or a qualified
technician may have to determine
if a
specific bulletin applies to your vehicle.
