SAE 1OW-30
As shown in the viscosity chart, SAE 1OW-30 is best
for
your vehicle. However, you can use SAE 5W-30
' if it's going to be colder than 60 OF (16 C) before
your next oil change. When it's very cold, below
O*F (-18*C), you should use SAE 5W-30.
These numbers on an oil container show its viscosity, or
thickness.
Do not use other viscosity oils such as SAE
1OW-40 or SAE 20W-50.

Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Buick
will:
Give freezing protection down to -34’F (-37 ’ C) .
0 Give boiling protection up to 262 ’ F ( 128 ’ C) .
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets “GM Specification 1825-M,” which won’t damage aluminum
parts. Use GM Engine Coolant Supplement (sealer) with
any complete coolant change. You can also use a
recycled coolant conforming to “GM Specifications
1825-M” with a complete coolant flush and-refill.
If you
use these, you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warnin!
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine coul
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
50150 mix of
clean water and
a proper antifreeze.
