What Kind Of Engine Oil To Use - Chevrolet 1998 Cavalier Owner's Manual

What Kind of Engine Oil to Use
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.
This is where you add oil if you have a 2.4L engine.
Be sure to 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.
If you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:
