Energy Conserving II
Oils with these words on the container will help you save fuel.
The doughnut-shaped logo (symbol) is used on most oil containers
to
help you select the correct oil.
You should look for this on the oil container, and use
only those oils
that display the logo.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
Engine Oil Additives: Don't add anything to your oil. Your General
Motors dealer is ready to advise
if you think something should be added.
When to Change Engine Oil:
See if any one of these is
true for you:
Most trips are less than
4 miles (6 km).
It's below freezing outside and most trips are less than 10 miles
(16 km).
The engine is at low speed most of the time (as
in door-to-door delivery,
or in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
If any one of these
is true for your vehicle, then you need to change
your oil and filter every
3,000
miles (5000 km) or 3 months-whichever
comes first.
If none of them is true, change the
oil every 7,500 miles (12 500 km) or
12 months-whichever comes
first. Change the filter at the first
oil
change and at every other oil change after that.
Engine Block Heater: An engine block heater can be a big help
if
you have
to park outside in very cold weather,
0°F (-18°C) or colder. If your vehicle
has this option, see "Engine Block Heater"
in the Index.
