1997 Oldsmobile Achieva oil viscosity

What Kind of Oil to Us
3100 Engine
The 2.4L engine oil fill cap is located on the passenger’s
side
of the engine. The 3100 engine oil fill cap is located
in front
of the engine, behind the fan.
Just fill it enough to put the level somewhere
in the
proper operating range. Push
the dipstick all the way
back in when you’re through. Oils recommended
for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
If you change your own oil,
be sure you use
oil that has
the Starburst symbol on the
front of the oil container. If
you have your oil changed
for
you, be sure the oil put
into your engine
is
American Petroleum
Institute certified for
gasoline enrzines.

You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

DO NOT USE SAE 2OW-50 OR ANY OTHER
GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1OW-30 if it’s going
to be
0°F (- 18 “C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 20W-50.
I 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.
