a drive gear where the engine runs
slower).

warning, you can drive. Just

You should look for this on the oil
container, and use
only those oils that
display the logo.

oil (in Canada, GM
Engine Oil) meets all
the requirements for
your vehicle.
Engine Oil Additives:
Don’t add anything to your oil. Your
Chevrolet 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:
0 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).
0 You tow a trailer often.
0 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 (5 000 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 OF (- 1 8 O C) or colder. If your
vehicle has this option, see “Engine Block
Heater’’
in the Index.
ProCarManuals.com

What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant
conforming to
GM Specification 1825M
with a complete coolant flush and refill.
If you use this mixture, you don’t need to
add anything else.
Adding only plain water to
- b your coding system can be
dangerous. Plain water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system is set for the proper coolant I
mix. With plain water or the wrong
mix, your engine could get too hot
but you wouldn’t get the overheat
warning. Your
engine could catch
fire and YOU or others could be
burned. Use a 50/50 mix of clean
water and a proper antifreeze.
--
I If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn’t be covered by your
warranty.
Too much water in 1-
mix can freeze and crack the engine,
radiator, heater core and other parts.
