gas mileage CHEVROLET OPTRA 5 2007 1.G Owners Manual

Part A: Scheduled Maintenance
Services
In this part are scheduled maintenance services
which are to be performed at the mileage intervals
specified.
Using the Maintenance Schedule
We at General Motors want to keep your vehicle
in good working condition. But we do not know
exactly how you will drive it. You may drive short
distances only a few times a week. Or you
may drive long distances all the time in very hot,
dusty weather. You may use your vehicle in
making deliveries. Or you may drive it to work, to
do errands, or in many other ways.
Because of the different ways people use their
vehicles, maintenance needs may vary. You may
need more frequent checks and replacements.
So please read the following and note how
you drive. If you have questions on how to keep
your vehicle in good condition, see your dealer.This part tells you the maintenance services you
should have done and when to schedule them.
When you go to your dealer for your service
needs, you will know that GM-trained and
supported service people will perform the work
using genuine GM parts.
The proper fluids and lubricants to use are listed
in Part 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.
These schedules are for vehicles that:
•carry passengers and cargo within
recommended limits. You will find these on
the Tire and Loading Information label.
SeeLoading Your Vehicle on page 236.
•are driven on reasonable road surfaces within
legal driving limits.
•use the recommended fuel. SeeGasoline
Octane on page 251.
