3800
Engine
As
shown in the chart, if you have the
3800
engine,
SAE
1OW-30 is best for your vehicle. However,
you
can
use
SAE
5W-30 if it’s going to be colder than
60°F
(16°C)
before your next oil change. When it’s very cold, 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
20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
GM
Goodwrench@ oil meets all the requirements for
your vehicle.
If
you are in an area where the temperature falls below
-20°F (-29”C),
consider using either an
SAE
5W-30
synthetic oil or an
SAE
OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
