Pontiac 2007 Torrent Owner's Manual page 441

When the change engine oil light and/or CHANGE
ENGINE OIL SOON message appears, certain
services, checks, and inspections are required.
Required services are described in the following
for "Maintenance I" and "Maintenance II."
Generally, it is recommended that your first service
be Maintenance I, your second service be
Maintenance II, and that you alternate
Maintenance I and Maintenance II thereafter.
However, in some cases, Maintenance II may be
required more often.
Maintenance I — Use Maintenance I if the
light/message comes on within 10 months since
the vehicle was purchased or Maintenance II
was performed.
Maintenance II — Use Maintenance II if the
previous service performed was Maintenance I.
Always use Maintenance II whenever the
light/message comes on 10 months or more since
the last service or if the light/message has not
come on at all for one year.
